The Arch Way

The design principles behind Arch are aimed at keeping it simple.

'Simple', in this context, shall mean 'without unnecessary additions, modifications, or complications'. In short; an elegant, minimalist approach.

Some thoughts to keep in mind as you consider simplicity:

  • " 'Simple' is defined from a technical standpoint, not a usability standpoint. It is better to be technically elegant with a higher learning curve, than to be easy to use and technically [inferior]." -Aaron Griffin
  • Entia non sunt multiplicanda praeter necessitatem or "Entities should not be multiplied unnecessarily." -Occam's razor. The term razor refers to the act of shaving away unnecessary complications to arrive at the simplest explanation, method or theory.
  • "The extraordinary part of [my method] lies in its simplicity..The height of cultivation always runs to simplicity." - Bruce Lee
About This Guide

The Arch wiki is an excellent resource and should be consulted for issues first. The IRC room (at freenode #archlinux), and the forums are also available if the answer cannot be found elsewhere.

Note: Following this guide closely is essential in order to successfully install a properly configured Arch Linux system, so please read it thoroughly. It is strongly recommended you read each section completely before carrying out the tasks contained.

Since GNU/Linux Distributions are fundamentally 'modular' by design, the guide is logically divided into 4 main components of a desktop UNIX-like operating system:

Part I: Installing the Base system

Part II: Configure & Update the New Arch Linux base system

Part III: Installing X and configuring ALSA

Part IV: Installing a Desktop Environment

Part I: Install the Base System

Step 1: Obtain the latest Installation media

You can obtain Arch's official installation media from here. The latest version is 2010.05

  • Both the Core and the Netinstall images provide only the necessary packages to create an Arch Linux base system. Note that the Base System does not include a GUI. It is mainly comprised of the GNU toolchain (compiler, assembler, linker, libraries, shell, and utilities), the Linux kernel, and a few extra libraries and modules.
  • Core images facilitate both installing from CD and Net.
  • Netinstall images are smaller and provide no packages themselves; the entire system is retrieved via internet.
  • The Arch64 FAQ can help you choose between the 32- and 64-bit versions.

Install from an Existing GNU/Linux Distro

Arch is flexible enough to be installed to another partition from within an existing distro or Live CD. See this wiki article for steps to do this. This can be useful particularly if you plan to install Arch via vnc or ssh remotely.

CD installer

Burn the .iso image file to a CD with your preferred CD burner drive and software, and continue with Step 2: Boot Arch Linux Installer

Note: The quality of optical drives, as well as the CD media itself, vary greatly. Generally, using a slow burn speed is recommended for reliable burns; Some users recommend speeds as low as 4x or 2x. If you are experiencing unexpected behavior from the CD, try burning at the minimum speed supported by your system.

USB stick

Warning: This procedure will irrevocably destroy all data on your USB stick!

UNIX Method:

Insert an empty or expendable USB stick, determine its path, and write the .iso to the USB stick with the /bin/dd program:

dd if=archlinux-2010.05-{core|netinstall}-{i686|x86_64|dual}.iso of=/dev/sdx

where if= is the path to the img file and of= is your USB device. Make sure to use /dev/sdx and not /dev/sdx1. You will need a usb stick large enough to accomodate the image which, at the time of this writing is 381MB.

Check md5sum:

Make a note of the number of records (blocks) read in and written out, then perform the following check:

dd if=/dev/sdx count=number_of_records status=noxfer | md5sum

The md5sum returned should match the md5sum of the downloaded archlinux image file; they both should match the md5sum of the image as listed in the md5sums file in the mirror distribution site. A typical run will look like this:

$ [sudo] dd if=archlinux-2010.05-core-i686.iso of=/dev/sdc
744973+0 records in
744973+0 records out
381426176 bytes (381 MB) copied, 106.611 s, 3.6 MB/s
$ [sudo] dd if=/dev/sdc count=744973 status=noxfer | md5sum
4850d533ddd343b80507543536258229  -
744973+0 records in
744973+0 records out

Microsoft Windows Method:

Download Disk Imager from https://launchpad.net/win32-image-writer/+download. Insert flash media. Start the Disk Imager and select the image file. Select the Drive letter associated with the flash drive. Click "write".

Continue with Step 2: Boot Arch Linux Installer

Step 2: Boot Arch Linux Installer

Insert the CD or USB stick and boot from it. You may have to change the boot order in your computer BIOS or press a key (usually DEL, F1, F2, F11 or F12) during the BIOS POST (Power On Self-Test) phase.

Tip: The memory requirements for a basic install are:
  • Core : 128 MB RAM x86_64/i686 (all packages selected, with swap partition)
  • Netinstall : 128 MB RAM x86_64/i686 (all packages selected, with swap partition)

The main menu should be displayed at this point. Select the preferred choice by using the arrow keys to highlight your choice, and then by pressing Enter.

Usually, the first item, Boot Archlive, is the preferred selection. However, choose Boot Archlive [legacy IDE] if you have trouble with libata/PATA, or have no SATA (Serial ATA) drives.

To change GRUB boot options, press e. Many users may wish to change the resolution of the framebuffer, for more readable console output. Append:

vga=773

to the kernel line, followed by <ENTER>, for a 1024x768 framebuffer. When done, press b to boot into that selection.

The system will now boot and present a login prompt. Login as 'root', without the quotes.

If your system has errors trying to boot from the live CD or there are other hardware errors, refer to the Installation Troubleshooting wiki page.

Changing the keymap

If you have a non-US keyboard layout you can interactively choose your keymap/console font with the command:

# km

or use the loadkeys command:

# loadkeys layout

(replace layout with your keyboard layout such as "fr" or "be-latin1")

Documentation

The official install guide is conveniently available right on the live system! To access it, change to vc/2 (virtual console #2) with <ALT>+F2, and then invoke /usr/bin/less by typing in the following at the # prompt:

# less /arch/docs/official_installation_guide_en

less will allow you to page through the document. Change back to vc/1 with <ALT>+F1 to follow the rest of the install process.

Change back to vc/2 at any time if you need to reference the Official Guide as you progress through the installation process.

Tip: Please note that the official guide only covers installation and configuration of the base system. Once that is installed, it is strongly recommended that you come back here to the wiki to find out more about post-installation considerations and other related issues.

Step 3: Start the Installation

As root, run the installer script from vc/1:

# /arch/setup

A: Select an installation source

After a welcome screen, you will be prompted for an installation source. Choose the appropriate source for the installer you are using.

  • If you chose the CORE installer, continue below with B: Set Clock.
  • Netinstall only: You shall be prompted to load ethernet drivers manually, if desired. Udev is quite effective at loading the required modules, so you may assume it has already done so. You may verify this by invoking ifconfig -a from vc/3. (Select OK to continue.)

Configure Network (Netinstall)

Available Interfaces will be presented. If an interface and HWaddr (HardWare address) is listed, then your module has already been loaded. If your interface is not listed, you may probe it from the installer, or manually do so from another virtual console.

The following screen will prompt you to Select the interface, Probe, or Cancel. Choose the appropriate interface and continue.

The installer will then ask if you wish to use DHCP. Choosing Yes will run dhcpcd to discover an available gateway and request an IP address; Choosing No will prompt you for your static IP, netmask, broadcast, gateway DNS IP, HTTP proxy, and FTP proxy. Lastly, you will be presented with an overview to ensure your entries are correct.

(A)DSL Quickstart for the Live Environment (If you have a pure modem (or router in bridge mode) to connect to your ISP)

Switch to another virtual console (<Alt> + F2), login as root and invoke

# pppoe-setup

If everything is well configured in the end you can connect to your ISP with

# pppoe-start

Return to first virtual console with <ALT>+F1. Continue with B: Set Clock

Wireless Quickstart For the Live Environment (If you need wireless connectivity during the installation process)

The wireless drivers and utilities are now available to you in the live environment of the installation media. A good knowledge of your wireless hardware will be of key importance to successful configuration. Note that the following quickstart procedure executed at this point in the installation will initialize your wireless hardware for use in the live environment. These steps (or some other form of wireless management) must be repeated from the actual installed system after booting into it.

Also note that these steps are optional if wireless connectivity is unnecessary at this point in the installation; wireless functionality may always be established later.

The basic procedure will be:

  • Switch to a free virtual console, e.g.: <ALT>+F3
  • Login as root
  • (Optional) Identify the wireless interface and driver module:
# lsmod | grep -i net
  • Ensure udev has loaded the driver, and that the driver has created a usable wireless kernel interface with /usr/sbin/iwconfig:
# iwconfig

Example output:

lo no wireless extensions.
eth0 no wireless extensions.
wlan0    unassociated  ESSID:""
         Mode:Managed  Channel=0  Access Point: Not-Associated   
         Bit Rate:0 kb/s   Tx-Power=20 dBm   Sensitivity=8/0  
         Retry limit:7   RTS thr:off   Fragment thr:off
         Power Management:off
         Link Quality:0  Signal level:0  Noise level:0
         Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
         Tx excessive retries:0  Invalid misc:0   Missed beacon:0

wlan0 is the available wireless interface in the example.

  • Bring the interface up with /sbin/ifconfig <interface> up.

An example using the wlan0 interface:

# ifconfig wlan0 up

(Remember, your interface may be named something else, depending on your module (driver) and chipset: wlan0, eth1, etc.)

  • If the essid has been forgotten or is unknown, use /sbin/iwlist <interface> scan to scan for nearby networks.
# iwlist wlan0 scan
  • Associate your wireless device with the access point you want to use. Depending on the encryption (none, WEP, or WPA), the procedure may differ. You need to know the name of the chosen wireless network (ESSID), e.g. 'linksys' in the following examples:
  • An example using a non-encrypted network:
# iwconfig wlan0 essid "linksys"
  • An example using WEP and a hexadecimal key:
# iwconfig wlan0 essid "linksys" key 0241baf34c
  • An example using WEP and an ASCII passphrase:
# iwconfig wlan0 essid "linksys" key s:pass1
  • Using WPA, the procedure requires a bit more work. Check WPA supplicant for more information and troubleshooting (or try using netcfg instead):
# wpa_passphrase linksys "secretpassphrase" > /etc/wpa_supplicant.conf
# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
  • Confirm you have successfully associated to the access point before continuing:
# iwconfig wlan0
  • Request an IP address with /sbin/dhcpcd <interface> . e.g.:
# dhcpcd wlan0
  • Ensure you can route using /bin/ping:
# ping -c 3 www.google.com

You should have a working network connection. For troubleshooting, check the detailed Wireless Setup page.

Does the Wireless Chipset require Firmware?

A small percentage of wireless chipsets also require firmware, in addition to a corresponding driver. If unsure, invoke /usr/bin/dmesg to query the kernel log for a firmware request from the wireless chipset:

# dmesg | grep firmware

Example output from an Intel chipset which requires and has requested firmware from the kernel at boot:

firmware: requesting iwlwifi-5000-1.ucode

If there is no output, it may be concluded that the system's wireless chipset does not require firmware.

Note: Wireless chipset firmware packages (for cards which require them) are pre-installed under /lib/firmware in the live environment, (on CD/USB stick) but must be explicitly installed to your actual system to provide wireless functionality after you reboot into it! Package selection and installation is covered below. Ensure installation of both your wireless module and firmware during the package selection step! See Wireless Setup if you are unsure about the requirement of corresponding firmware installation for your particular chipset. This is a very common error.

After the initial Arch installation is complete, you may wish to refer to Wireless Setup to ensure a permanent configuration solution for your installed system.

Return to vc/1 with <ALT>+F1. Continue with B: Set Clock

B: Set Clock

  • UTC - Choose UTC if running only UNIX-like operating system(s).
  • localtime - Choose local if multi-booting with a Microsoft Windows OS.

C: Prepare Hard Drive

Warning: Partitioning hard drives can destroy data. You are strongly cautioned and advised to backup your critical data if applicable.
Note: Partitioning may be performed before initiating the Arch installation if desired, by utilizing GParted or other available tools. If the installation drive has already been partitioned to the required specifications, continue with Set Filesystem Mountpoints

Verify current disk identities and layout by invoking /sbin/fdisk with the -l (lower-case L) switch.

Open another virtual console (<ALT>+F3) and enter:

# fdisk -l

Take note of the disk(s)/partition(s) to utilize for the Arch installation.

Switch back to the installation script with <ALT>+F1

Select the first menu entry "Prepare Hard Drive".

  • Option 1: Auto Prepare

Auto-Prepare divides the disk into the following configuration:

  • ext2 /boot partition, default size 32MB. You will be prompted to modify the size to your requirement.
  • swap partition, default size 256MB. You will be prompted to modify the size to your requirement.
  • A Separate / and /home partition, (sizes can also be specified). Available filesystems include ext2, ext3, ext4, reiserfs, xfs and jfs, but note that both / and /home shall share the same fs type if choosing the Auto Prepare option.

Be warned that Auto-prepare will completely erase the chosen hard drive. Read the warning presented by the installer very carefully, and make sure the correct device is about to be partitioned.

  • Option 2: (Recommended) Partition Hard Drives (with cfdisk)

This option will allow for the most robust and customized partitioning solution for your personal needs.

At this point, more advanced GNU/Linux users who are familiar and comfortable with manually partitioning may wish to skip down to D: Select Packages below.

Note: If you are installing to a USB flash key, see "Installing Arch Linux on a USB key".

Partition Hard Drives

Partition Info

Partitioning a hard disk drive defines specific areas (the partitions) within the disk, that will each appear and behave as a separate disk and upon which a filesystem may be created (formatted).

  • There are 3 types of disk partitions:
  1. Primary
  2. Extended
  3. Logical

Primary partitions can be bootable, and are limited to 4 partitions per disk or raid volume. If a partitioning scheme requires more than 4 partitions, an extended partition which will contain logical partitions will be required.

Extended partitions are not usable by themselves; they are merely a "container" for logical partitions. If required, a hard disk shall contain only one extended partition; which shall then be sub-divided into logical partitions.

When partitioning a disk, one can observe this numbering scheme by creating primary partitions sda1 through sda3 followed by creating an extended partition, sda4, and subsequently creating logical partition(s) within the extended partition; sda5, sda6, and so on.

Swap Partition

A swap partition is a place on the drive where virtual ram resides, allowing the kernel to easily use disk storage for data that does not fit into physical RAM.

Historically, the general rule for swap partition size was 2x the amount of physical RAM. Over time, as computers have gained ever larger memory capacities, this rule has become increasingly deprecated. Generally, on machines with up to 512MB RAM, the 2x rule is usually quite sufficient. If the installation machine provides gratuitous amounts of RAM (more than 1024 MB) it may be possible to completely forget a swap partition altogether, since the option to create a swap file is always available later. A 1 GB swap partition will be used in this example.

Note: If using suspend-to-disk, (hibernate) a swap partition at least equal in size to the amount of physical RAM is required. Some Arch users even recommend oversizing it beyond the amount of physical RAM by 10-15%, to allow for possible bad sectors.
Partition Scheme

A disk partitioning scheme is a very personalized preference. Each user's choices will be unique to their own computing habits and requirements. If you would like to dual boot Arch Linux and a Windows operating system please see Windows and Arch Dual Boot.

Filesystem candidates for separate partitions include:

/ (root) The root filesystem is the primary filesystem from which all other filesystems stem; the top of the hierarchy. All files and directories appear under the root directory "/", even if they are stored on different physical devices. The contents of the root filesystem must be adequate to boot, restore, recover, and/or repair the system. Therefore, certain directories under / are not themselves candidates for separate partitions. (See warning below).

/boot This directory contains the kernel and ramdisk images as well as the bootloader configuration file, and bootloader stages. /boot also stores data that is used before the kernel begins executing userspace programs. This may include saved master boot sectors and sector map files. /boot is essential for booting, but is unique in that it may still be kept on its own separate partition (if required).

/home Provides subdirectories, each named for a system user, for miscellaneous personal data storage as well as user-specific configuration files for applications.

/usr While root is the primary filesystem, /usr is the secondary hierarchy for all system users' data, including the majority of multi-user utilities and applications. /usr is shareable, read-only data. This means that /usr shall be shareable between various hosts and must not be written to, except in the case of system update/upgrade. Any information that is host-specific or varies with time is stored elsewhere.

/tmp directory for programs that require temporary files such as '.lck' files, which can be used to prevent multiple instances of their respective program until a task is completed, at which point the '.lck' file will be removed. Programs must not assume that any files or directories in /tmp are preserved between invocations of the program and files and directories located under /tmp will typically be deleted whenever the system is booted.

/var contains variable data; spool directories and files, administrative and logging data, pacman's cache, the ABS tree, etc. /var exists in order to make it possible to mount /usr as read-only. Everything that historically went into /usr that is written to during system operation (as opposed to installation and software maintenance) must reside under /var.

Warning: Besides /boot, directories essential for booting are: '/bin', '/etc', '/lib', and '/sbin'. Therefore, they must not reside on a separate partition from /.

There are several advantages for using discrete filesystems, rather than combining all into one partition:

  • Security: Each filesystem may be configured in /etc/fstab as 'nosuid', 'nodev', 'noexec', 'readonly', etc.
  • Stability: A user, or malfunctioning program can completely fill a filesystem with garbage if they have write permissions for it. Critical programs, which reside on a different filesystem remain unaffected.
  • Speed: A filesystem which gets written to frequently may become somewhat fragmented. (An effective method of avoiding fragmentation is to ensure that each filesystem is never in danger of filling up completely.) Separate filesystems remain unaffected, and each can be defragmented separately as well.
  • Integrity: If one filesystem becomes corrupted, separate filesystems remain unaffected.
  • Versatility: Sharing data across several systems becomes more expedient when independent filesystems are used. Separate filesystem types may also be chosen based upon the nature of data and usage.

In this example, we shall use separate partitions for /, /var, /home, and a swap partition.

Note: /var contains many small files. This should be taken into consideration when choosing a filesystem type for it, (if creating its own separate partition).
How big should my partitions be?

This question is best answered based upon individual needs. You may wish to simply create one partition for root and one partition for swap or only one root partition without swap or refer to the following examples and consider these guidelines to provide a frame of reference:

  • The root filesystem (/) in the example will contain the /usr directory, which can become moderately large, depending upon how much software is installed. 15-20 GB should be sufficient for most users.
  • The /var filesystem will contain, among other data, the ABS tree and the pacman cache. Keeping cached packages is useful and versatile; it provides the ability to downgrade packages if needed. /var tends to grow in size; the pacman cache can grow large over long periods of time, but can be safely cleared if needed. If you are using an SSD, you may wish to locate your /var on an HDD and keep the / and /home partitions on your SSD to avoid needless read/writes to the SSD. 8-12 Gigs on a desktop system should be sufficient for /var, depending largely upon how much software you intend to install. Servers tend to have relatively larger /var filesystems.
  • The /home filesystem is typically where user data, downloads, and multimedia reside. On a desktop system, /home is typically the largest filesystem on the drive by a large margin. Remember that if you chose to reinstall Arch, all the data on your /home partition will be untouched (so long as you have a separate /home partition).
  • An extra 25% of space added to each filesystem will provide a cushion for unforeseen occurrence, expansion, and serve as a preventive against fragmentation.

From the guidelines above, the example system shall contain a ~15GB root (/) partition, ~10GB /var, 1GB swap, and a /home containing the remaining disk space.

Create Partition:cfdisk

Start by creating the primary partition that will contain the root, (/) filesystem.

Choose New -> Primary and enter the desired size for root (/). Put the partition at the beginning of the disk.

Also choose the Type by designating it as '83 Linux'. The created / partition shall appear as sda1 in our example.

Now create a primary partition for /var, designating it as Type 83 Linux. The created /var partition shall appear as sda2

Next, create a partition for swap. Select an appropriate size and specify the Type as 82 (Linux swap / Solaris). The created swap partition shall appear as sda3.

Lastly, create a partition for your /home directory. Choose another primary partition and set the desired size.

Likewise, select the Type as 83 Linux. The created /home partition shall appear as sda4.

Example:

Name    Flags     Part Type    FS Type           [Label]         Size (MB)
-------------------------------------------------------------------------
sda1               Primary     Linux                             15440 #root
sda2               Primary     Linux                             10256 #/var
sda3               Primary     Linux swap / Solaris              1024  #swap
sda4               Primary     Linux                             140480 #/home

Choose Write and type 'yes'. Beware that this operation may destroy data on your disk. Choose Quit to leave the partitioner. Choose Done to leave this menu and continue with "Set Filesystem Mountpoints".

Note: Since the latest developments of the Linux kernel which include the libata and PATA modules, all IDE, SATA and SCSI drives have adopted the sdx naming scheme. This is perfectly normal and should not be a concern.

Set Filesystem Mountpoints

First you will be asked for your swap partition. Choose the appropriate partition (sda3 in this example). You will be asked if you want to create a swap filesystem; select yes. Next, choose where to mount the / (root) directory (sda1 in the example). At this time, you will be asked to specify the filesystem type.

Filesystem Types

Again, a filesystem type is a very subjective matter which comes down to personal preference. Each has its own advantages, disadvantages, and unique idiosyncrasies. Here is a very brief overview of supported filesystems:

1. ext2 Second Extended Filesystem- Old, reliable GNU/Linux filesystem. Very stable, but without journaling support. May be inconvenient for root (/) and /home, due to very long fsck's. An ext2 filesystem can easily be converted to ext3. Generally regarded as a good choice for /boot/.

2. ext3 Third Extended Filesystem- Essentially the ext2 system, but with journaling support. ext3 is backward compatible with ext2. Extremely stable, mature, and by far the most widely used, supported and developed GNU/Linux FS.

High Performance Filesystems:

3. ext4 Fourth Extended Filesystem- Backward compatible with ext2 and ext3. Introduces support for volumes with sizes up to 1 exabyte and files with sizes up to 16 terabytes. Increases the 32,000 subdirectory limit in ext3 to 64,000. Offers online defragmentation ability.

4. ReiserFS (V3)- Hans Reiser's high-performance journaling FS uses a very interesting method of data throughput based on an unconventional and creative algorithm. ReiserFS is touted as very fast, especially when dealing with many small files. ReiserFS is fast at formatting, yet comparatively slow at mounting. Quite mature and stable. ReiserFS is not actively developed at this time (Reiser4 is the new Reiser filesystem). Generally regarded as a good choice for /var/.

5. JFS - IBM's Journaled FileSystem- The first filesystem to offer journaling. JFS had many years of use in the IBM AIX® OS before being ported to GNU/Linux. JFS currently uses the least CPU resources of any GNU/Linux filesystem. Very fast at formatting, mounting and fsck's, and very good all-around performance, especially in conjunction with the deadline I/O scheduler. (See JFS.) Not as widely supported as ext or ReiserFS, but very mature and stable.

6. XFS - Another early journaling filesystem originally developed by Silicon Graphics for the IRIX OS and ported to GNU/Linux. XFS offers very fast throughput on large files and large filesystems. Very fast at formatting and mounting. Generally benchmarked as slower with many small files, in comparison to other filesystems. XFS is very mature and offers online defragmentation ability.

  • JFS and XFS filesystems cannot be shrunk by disk utilities (such as gparted or parted magic)
A note on Journaling

All above filesystems, except ext2, utilize journaling. Journaling file systems are fault-resilient file systems that use a journal to log changes before they are committed to the file system to avoid metadata corruption in the event of a crash. Note that not all journaling techniques are alike; specifically, only ext3 and ext4 offer data-mode journaling, (though, not by default), which journals both data and meta-data (but with a significant speed penalty). The others only offer ordered-mode journaling, which journals meta-data only. While all will return your filesystem to a valid state after recovering from a crash, data-mode journaling offers the greatest protection against file system corruption and data loss but can suffer from performance degradation, as all data is written twice (first to the journal, then to the disk). Depending upon how important your data is, this may be a consideration in choosing your filesystem type.

Moving on...

Choose and create the filesystem (format the partition) for / by selecting yes. You will now be prompted to add any additional partitions. In our example, sda2 and sda4 remain. For sda2, choose a filesystem type and mount it as /var. Finally, choose the filesystem type for sda4, and mount it as /home.

Note: If you have not created and do not need a separate /boot partition, you may safely ignore the warning that it does not exist.
Return to the main menu.

D: Select Packages

  • Core ISO: Choose CD as source and select the appropriate CD drive if more than one exist on the installation machine.
  • Netinstall: Select an FTP/HTTP mirror. Note that archlinux.org is throttled to 50KB/s.
  • All packages during installation are from the [core] repository. They are further divided into Base, and Base-devel.
  • Package information and brief descriptions are available here.

Package selection is split into two stages. First, select the package category:

Note: For expedience, all packages in base are selected by default. Use the space-bar to select and de-select packages.
  • Base: Packages from the [core] repo to provide the minimal base environment. Always select it and only remove packages that will not be used.
  • Base-devel: Extra tools from [core] such as make, and automake. Most beginners should choose to install it, and will probably need it later.

After category selection, you will be presented with the full lists of packages, allowing you to fine-tune your selections. Use the space bar to select and unselect.

Note: If connection to a wireless network is required, remember to select and install the wireless_tools package. Some wireless interfaces also need ndiswrapper and/or a specific firmware. If you plan to use WPA encryption, you will need wpa_supplicant. The Wireless Setup page will help you choose the correct packages for your wireless device. Also strongly consider installing netcfg, which will help you set up your network connection and profiles.

After selecting the needed packages, leave the selection screen and continue to the next step, Install Packages.

E: Install Packages

Next, choose 'Install Packages'. You will be asked if you wish to keep the packages in the pacman cache. If you choose 'yes', you will have the flexibility to downgrade to previous package versions in the future, so this is recommended (you can always clear the cache in the future). The installer script will now install the selected packages, as well as the default Arch 2.6 kernel, to your system.

  • Netinstall: The Pacman package manager will now download and install your selected packages. (See vc/5 for output, vc/1 to return to the installer)
  • Core image: The packages will be installed from the CD/USB stick.

F: Configure the System

Closely following and understanding these steps is of key importance to ensure a properly configured system.

  • At this stage of the installation, you will configure the primary configuration files of your Arch Linux base system.
  • Previous versions of the installer included hwdetect to gather information for your configuration. This has been deprecated, and udev should handle most module loading automatically at boot.

Now you will be asked which text editor you want to use; choose nano, joe or vi, (nano is generally considered easiest of the 3). You will be presented with a menu including the main configuration files for your system.

Note: It is very important at this point to edit, or at least verify by opening, every configuration file. The installer script relies on your input to create these files on your installation. A common error is to skip over these critical steps of configuration.
Can the installer handle this more automatically?

Hiding the process of system configuration is in direct opposition to The Arch Way. While it is true that recent versions of the kernel and hardware probing tools offer excellent hardware support and auto-configuration, Arch presents the user all pertinent configuration files during installation for the purposes of transparency and system resource control. By the time you have finished modifying these files to your specifications, you will have learned the simple method of manual Arch Linux system configuration and become more familiar with the base structure, leaving you better prepared to use and maintain your new installation productively.

Moving on...

/etc/rc.conf

Arch Linux uses the file /etc/rc.conf as the principal location for system configuration. This one file contains a wide range of configuration information, principally used at system startup. As its name directly implies, it also contains settings for and invokes the /etc/rc* files, and is, of course, sourced by these files.

LOCALIZATION section
  • LOCALE=: This sets your system locale, which will be used by all i18n-aware applications and utilities. You can get a list of the available locales by running locale -a from the command line. This setting's default is fine for US English users.
  • HARDWARECLOCK=: Specifies whether the hardware clock, which is synchronized on boot and on shutdown, stores UTC time, or localtime. UTC makes sense because it greatly simplifies changing timezones and daylight savings time. localtime is necessary if you dual boot with an operating system such as Windows, that only stores localtime to the hardware clock.
  • USEDIRECTISA=: Use direct I/O request instead of /dev/rtc for hwclock
  • TIMEZONE=: Specify your TIMEZONE. (All available zones are under /usr/share/zoneinfo/).
  • KEYMAP=: The available keymaps are in /usr/share/kbd/keymaps. Please note that this setting is only valid for your TTYs, not any graphical window managers or X.
  • CONSOLEFONT=: Available console fonts reside under /usr/share/kbd/consolefonts/ if you must change. The default (blank) is safe.
  • CONSOLEMAP=: Defines the console map to load with the setfont program at boot. Possible maps are found in /usr/share/kbd/consoletrans, if needed. The default (blank) is safe.
  • USECOLOR=: Select "yes" if you have a color monitor and wish to have colors in your consoles.
LOCALE="en_US.utf8"
HARDWARECLOCK="localtime"
USEDIRECTISA="no"
TIMEZONE="US/Eastern"
KEYMAP="us"
CONSOLEFONT=
CONSOLEMAP=
USECOLOR="yes"
HARDWARE Section
  • MOD_AUTOLOAD=: Setting this to "yes" will use udev to automatically probe hardware and load the appropriate modules during boot, (convenient with the default modular kernel). Setting this to "no" will rely on the user's ability to specify this information manually, or compile their own custom kernel and modules, etc.
  • MOD_BLACKLIST=: This has become deprecated in favor of adding blacklisted modules directly to the MODULES= line below.
  • MODULES=: Specify additional MODULES if you know that an important module is missing. If your system has any floppy drives, add "floppy". If you will be using loopback filesystems, add "loop". Also specify any blacklisted modules by prefixing them with a bang (!). Udev will be forced NOT to load blacklisted modules. In the example, the IPv6 module as well as the annoying pcspeaker are blacklisted.
# Scan hardware and load required modules at boot
MOD_AUTOLOAD="yes"
# Module Blacklist - Deprecated
MOD_BLACKLIST=()
#
MODULES=(!net-pf-10 !snd_pcsp !pcspkr loop)
NETWORKING Section
  • HOSTNAME=:Set your HOSTNAME to your liking. This is the name of your computer. Whatever you put here, also put it in /etc/hosts
  • eth0=: 'Ethernet, card 0'. If you are using static IP, adjust the interface IP address, netmask and broadcast address. Set eth0="dhcp" if you want to use DHCP for dynamic/automatic configuration.
  • INTERFACES=: Specify all interfaces here. Multiple interfaces should be separated with a space as in:
(eth0 wlan0)
  • gateway=: If you are using static IP, set the gateway address. If using DHCP, you can usually ignore this variable, though some users have reported the need to define it.
  • ROUTES=: If you are using static IP, remove the ! in front of 'gateway'. If using DHCP, you can usually leave this variable commented out with the bang (!), but again, some users require the gateway and ROUTES defined. If you experience networking issues with pacman, for instance, you may want to return to these variables.
Example, using a dynamically assigned IP address (DHCP)
HOSTNAME="arch"
#eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
eth0="dhcp"
INTERFACES=(eth0)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
Example, using a static IP address
HOSTNAME="arch"
eth0="eth0 192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.255"
INTERFACES=(eth0)
gateway="default gw 192.168.0.1"
ROUTES=(gateway)

Modify /etc/resolv.conf to specify the DNS servers of choice. Example:

search my.isp.net.
nameserver 4.2.2.1
nameserver 4.2.2.2
nameserver 4.2.2.3

Various processes can overwrite the contents of /etc/resolv.conf. For example, by default Arch Linux uses the dhcpcd DHCP client, which will overwrite the file when it starts. Various methods may be used to preserve the nameserver settings in /etc/resolv.conf. For example, dhcpcd's configurations file may be edited to prevent the dhcpcd daemon from overwriting the file. To do this, you will need to append this to the end of /etc/dhcpcd.conf:

nohook resolv.conf
Tip: If using a non-standard MTU size (a.k.a. jumbo frames) is desired AND the installation machine hardware supports them, see the Jumbo Frames wiki article for further configuration.
DAEMONS Section

This array simply lists the names of those scripts contained in /etc/rc.d/ which are to be started during the boot process, and the order in which they start. Asynchronous initialization by backgrounding is also supported and useful for speeding up boot.

DAEMONS=(network @syslog-ng netfs @crond)
  • If a script name is prefixed with a bang (!), it is not executed.
  • If a script is prefixed with an "at" symbol (@), it shall be executed in the background; the startup sequence will not wait for successful completion of each daemon before continuing to the next. (Useful for speeding up system boot). Do not background daemons that are needed by other daemons. For example "mpd" depends on "network", therefore backgrounding network may cause mpd to break.
  • Edit this array whenever new system services are installed, if starting them automatically during boot is desired.
Note: This 'BSD-style' init, is the Arch way of handling what other distributions handle with various symlinks to an /etc/init.d directory.
About DAEMONS

The daemons line need not be changed at this time, but it is useful to explain what daemons are, as they will be addressed later in this guide. A daemon is a program that runs in the background, waiting for events to occur and offering services. A good example is a webserver that waits for a request to deliver a page (e.g.:httpd) or an SSH server waiting for a user login (e.g.:sshd). While these are full-featured applications, there are also daemons whose work is not that visible. Examples are a daemon which writes messages into a log file (e.g. syslog, metalog), a daemon which lowers the CPU frequency if the system has nothing to do (e.g.:cpufreq), and a daemon which provides a graphical login (e.g.: gdm, kdm). All these programs can be added to the daemons line and will be started when the system boots. Useful daemons will be presented during this guide.

Historically, the term daemon was coined by the programmers of MIT's Project MAC. They took the name from Maxwell's demon, an imaginary being from a famous thought experiment that constantly works in the background, sorting molecules. UNIX systems inherited this terminology and created the backronym disk and execution monitor.

Tip: All Arch daemons reside under /etc/rc.d/

/etc/fstab

The fstab (for file systems table) is part of the system configuration listing all available disks and disk partitions, and indicating how they are to be initialized or otherwise integrated into the overall system's filesystem. The /etc/fstab file is most commonly used by the mount command. The mount command takes a filesystem on a device, and adds it to the main system hierarchy that you see when you use your system. mount -a is called from /etc/rc.sysinit, about 3/4 of the way through the boot process, and reads /etc/fstab to determine which options should be used when mounting the specified devices therein. If noauto is appended to a filesystem in /etc/fstab, mount -a will not mount it at boot.

An example /etc/fstab
# <file system>        <dir>        <type>        <options>                 <dump>    <pass>
none                   /dev/pts     devpts        defaults                       0         0
none                   /dev/shm     tmpfs         defaults                       0         0
#/dev/cdrom            /media/cdrom   auto        ro,user,noauto,unhide          0         0
#/dev/dvd              /media/dvd     auto        ro,user,noauto,unhide          0         0
#/dev/fd0              /media/fl      auto        user,noauto                    0         0
/dev/sda1                   /          jfs        defaults,noatime               0         1
/dev/sda2                   /var     reiserfs     defaults,noatime,notail        0         2
/dev/sda3                    swap     swap        defaults                       0         0
/dev/sda4                   /home      jfs        defaults,noatime               0         2
Note: The 'noatime' option disables writing read access times to the metadata of files and may safely be appended to / and /home regardless of your specified filesystem type for increased speed, performance, and power efficiency (see here for more). 'notail' disables the ReiserFS tailpacking feature, for added performance at the cost of slightly less efficient disk usage.
  • <file system>: describes the block device or remote filesystem to be mounted. For regular mounts, this field will contain a link to a block device node (as created by mknod which is called by udev at boot) for the device to be mounted; for instance, '/dev/cdrom' or '/dev/sda1'.
Note: If your system has more than one hard drive, the installer will default to using UUID rather than the sdx naming scheme, for consistent device mapping. Utilizing UUID has several advantages and may also be preferred to avoid issues if hard disks are added to the system in the future. Due to active developments in the kernel and also udev, the ordering in which drivers for storage controllers are loaded may change randomly, yielding an unbootable system/kernel panic. Nearly every motherboard has several controllers (onboard SATA, onboard IDE), and due to the aforementioned development updates, /dev/sda may become /dev/sdb on the next reboot. (See this wiki article for more information on persistent block device naming. )
  • <dir>: describes the mount point for the filesystem. For swap partitions, this field should be specified as 'swap'; (Swap partitions are not actually mounted.)
  • <type>: describes the type of the filesystem. The Linux kernel supports many filesystem types. (For the filesystems currently supported by the running kernel, see /proc/filesystems). An entry 'swap' denotes a file or partition to be used for swapping. An entry 'ignore' causes the line to be ignored. This is useful to show disk partitions which are currently unused.
  • <options>: describes the mount options associated with the filesystem. It is formatted as a comma-separated list of options with no intervening spaces. It contains at least the type of mount plus any additional options appropriate to the filesystem type. For documentation on the available options for non-nfs file systems, see mount(8).
  • <dump>: used by the dump(8) command to determine which filesystems are to be dumped. dump is a backup utility. If the fifth field is not present, a value of zero is returned and dump will assume that the filesystem does not need to be backed up. Note that dump is not installed by default.
  • <pass>: used by the fsck(8) program to determine the order in which filesystem checks are done at boot time. The root filesystem should be specified with a <pass> of 1, and other filesystems should have a <pass> of 2 or 0. Filesystems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked.
  • If you plan on using hal to automount media such as DVDs, you may wish to comment out the cdrom and dvd entries in preparation for hal, which will be installed later in this guide.

Expanded information available in the Fstab wiki entry.

/etc/mkinitcpio.conf

Most users will not need to modify this file at this time, but please read the following explanatory information.

This file allows further fine-tuning of the initial ram filesystem, or initramfs, (also historically referred to as the initial ramdisk or "initrd") for your system. The initramfs is a gzipped image that is read by the kernel during boot. The purpose of the initramfs is to bootstrap the system to the point where it can access the root filesystem. This means it has to load any modules that are required for devices like IDE, SCSI, or SATA drives (or USB/FW, if you are booting from a USB/FW drive). Once the initrramfs loads the proper modules, either manually or through udev, it passes control to the kernel and your boot continues. For this reason, the initramfs only needs to contain the modules necessary to access the root filesystem. It does not need to contain every module you would ever want to use. The majority of common kernel modules will be loaded later on by udev, during the init process.

mkinitcpio is the next generation of initramfs creation. It has many advantages over the old mkinitrd and mkinitramfs scripts.

  • It uses glibc and busybox to provide a small and lightweight base for early userspace.
  • It can use udev for hardware autodetection at runtime, thus prevents you from having tons of unnecessary modules loaded.
  • Its hook-based init script is easily extendable with custom hooks, which can easily be included in pacman packages without having to modifiy mkinitcpio itself.
  • It already supports lvm2, dm-crypt for both legacy and luks volumes, raid, swsusp and suspend2 resuming and booting from usb mass storage devices.
  • Many features can be configured from the kernel command line without having to rebuild the image.
  • The mkinitcpio script makes it possible to include the image in a kernel, thus making a self-contained kernel image is possible.
  • Its flexibility makes recompiling a kernel unnecessary in many cases.

If using RAID or LVM on the root filesystem, the appropriate HOOKS must be configured. See the wiki pages for RAID and /etc/mkinitcpio for more info. If using a non-US keyboard. add the "keymap" hook to load your local keymap during boot. Add the "usbinput" hook if using a USB keyboard, e.g.:

HOOKS="base udev autodetect pata scsi sata filesystems keymap usbinput"

(Otherwise, if boot fails for some reason you will be asked to enter root's password for system maintenance but will be unable to do so.)

If you need support for booting from USB devices, FireWire devices, PCMCIA devices, NFS shares, software RAID arrays, LVM2 volumes, encrypted volumes, or DSDT support, configure your HOOKS accordingly.

If doing a CF or SD card install, you may need to add the usbinput HOOK for your system to boot properly.

If you are using a US keyboard, and have no need for any of the above HOOKS, editing this configuration should be unnecessary at this point.

mkinitcpio is an Arch innovation developed by Aaron Griffin and Tobias Powalowski with some help from the community.

/etc/modprobe.d/modprobe.conf

This file can be used to set special configuration options for the kernel modules. It is unnecessary to configure this file in the example.

/etc/resolv.conf (for Static IP)

The resolver is a set of routines in the C library that provide access to the Internet Domain Name System (DNS). One of the main functions of DNS is to translate domain names into IP addresses, to make the Web a friendlier place. The resolver configuration file, or /etc/resolv.conf, contains information that is read by the resolver routines the first time they are invoked by a process.

  • If you are using DHCP, you may safely ignore this file, as by default, it will be dynamically created and destroyed by the dhcpcd daemon. You may change this default behavior if you wish. (See Network]).

If you use a static IP, set your DNS servers in /etc/resolv.conf (nameserver <ip-address>). You may have as many as you wish. An example, using OpenDNS:

nameserver 208.67.222.222
nameserver 208.67.220.220

If you are using a router, you will probably want to specify your DNS servers in the router itself, and merely point to it from your /etc/resolv.conf, using your router's IP (which is also your gateway from /etc/rc.conf), e.g.:

nameserver 192.168.1.1

If using DHCP, you may also specify your DNS servers in the router, or allow automatic assignment from your ISP, if your ISP is so equipped.

/etc/hosts

This file associates IP addresses with hostnames and aliases, one line per IP address. For each host a single line should be present with the following information:

<IP-address> <hostname> [aliases...]

Add your hostname, coinciding with the one specified in /etc/rc.conf, as an alias, so that it looks like this:

127.0.0.1   localhost.localdomain   localhost yourhostname
Note: This format, including the 'localhost' and your actual host name, is required for program compatibility! So, if you have named your computer "arch", then that line above should look like this:
127.0.0.1   localhost.localdomain   localhost arch
Errors in this entry may cause poor network performance and/or certain programs to open very slowly, or not work at all. This is a very common error for beginners.

If you use a static IP, add another line using the syntax: <static-IP> <hostname.domainname.org> <hostname> e.g.:

192.168.1.100 yourhostname.domain.org  yourhostname
Tip: For convenience, you may also use /etc/hosts aliases for hosts on your network, and/or on the Web, e.g.:
64.233.169.103   www.google.com   g
192.168.1.90   media
192.168.1.88   data
The above example would allow you to access google simply by typing 'g' into your browser, and access to a media and data server on your network by name and without the need for typing out their respective IP addresses.

/etc/hosts.deny and /etc/hosts.allow

Modify these configurations according to your needs if you plan on using the ssh daemon. The default configuration will reject all incoming connections, not only ssh connections. Edit your /etc/hosts.allow file and add the appropriate parameters:

  • let everyone connect to you
sshd: ALL
  • restrict it to a certain ip
sshd: 192.168.0.1
  • restrict it to your local LAN network (range 192.168.0.0 to 192.168.0.255)
sshd: 192.168.0.
  • OR restrict for an IP range
sshd: 10.0.0.0/255.255.255.0

If you do not plan on using the ssh daemon, leave this file at the default, (empty), for added security.

/etc/locale.gen

The /usr/sbin/locale-gen command reads from /etc/locale.gen to generate specific locales. They can then be used by glibc and any other locale-aware program or library for rendering text, correctly displaying regional monetary values, time and date formats, alphabetic idiosyncrasies, and other locale-specific standards.

By default /etc/locale.gen is an empty file with commented documentation. Once edited, the file remains untouched. locale-gen runs on every glibc upgrade, generating all the locales specified in /etc/locale.gen.

Choose the locale(s) you need (remove the # in front of the lines you want), e.g.:

en_US ISO-8859-1
en_US.UTF-8	

The installer will now run the locale-gen script, which will generate the locales you specified. You may change your locale in the future by editing /etc/locale.gen and subsequently running 'locale-gen' as root.

Note: If you fail to choose your locale, this will lead to a "The current locale is invalid..." error. This is perhaps the most common mistake by new Arch users, and also leads to the most commonly asked questions on the forum.

Pacman-Mirror

Choose a mirror repository for pacman.

  • archlinux.org is throttled, limiting downloads to 50KB/s

Root password

Finally, set a root password and make sure that you remember it later. Return to the main menu and continue with installing bootloader.

G: Install Bootloader

Because we have no secondary operating system in our example, we will need a bootloader. GNU GRUB is the recommended bootloader. Alternatively, you may choose LILO.

GRUB

The provided GRUB configuration (/boot/grub/menu.lst) should be sufficient, but verify its contents to ensure accuracy (specifically, ensure that the root (/) partition is specified by UUID on line 3). You may want to alter the resolution of the console by adding a vga=<number> kernel argument corresponding to your desired virtual console resolution. (A table of resolutions and the corresponding numbers is printed in the menu.lst.)

Example:

title  Arch Linux (Main)
root   (hd0,0) 
kernel /boot/vmlinuz26 root=/dev/sda1 ro vga=773
initrd /boot/kernel26.img
Note: The linux kernel, 'vmlinuz', is so named because it incorporated virtual memory capability early in its development. The z denotes a zipped (compressed) image.

Example for /boot on the separate partition:

title  Arch Linux (Main)
root   (hd0,0) 
kernel /vmlinuz26 root=/dev/sda3 ro vga=773
initrd /kernel26.img

Explanation:

Line 1: title: A printed menu selection. "Arch Linux (Main)" will be printed on the screen as a menu selection.

Line 2: root: GRUB's root; the drive and partition where the kernel (/boot) resides, according to system BIOS. (More accurately, where GRUB's stage2 file resides). NOT necessarily the root (/) file system, as they can reside on separate partitions. GRUB's numbering scheme starts at 0, and uses an hdx,x format regardless of IDE or SATA, and enclosed within parentheses.

The example indicates that /boot is on the first partition of the first drive, according to BIOS, or, (hd0,0).

Line 3: kernel: This line specifies:

  • The path and filename of the kernel relative to GRUB's root.

In the example, /boot is merely a directory residing on the same partition as / and vmlinuz26 is the kernel filename; /boot/vmlinuz26. If /boot were on a separate partition, the path and filename would be simply /vmlinuz26, being relative to GRUB's root.

  • The root= argument to the kernel statement specifies the partition containing the root (/) directory in the booted system, (more accurately, the partition containing /sbin/init).
  • An easy way to distinguish the 2 appearances of 'root' in /boot/grub/menu.lst is to remember that the first root statement informs GRUB where the kernel resides, whereas the second root= kernel argument tells the kernel where the root filesystem (/) resides.
  • Kernel options.

In our example, ro mounts the filesystem as read only during startup, (usually a safe default; you may wish to change this in case it causes problems booting) and the "vga=773" argument will give a 1024x768 framebuffer with 256 color depth.

Line 4: initrd: (For Initial RAM disk) The path and filename of the initial RAM filesystem relative to GRUB's root. Again, in the example, /boot is merely a directory residing on the same partition as / and kernel26.img is the initrd filename; /boot/kernel26.img. If /boot were on a separate partition, the path and filename would be simply /kernel26.img, being relative to GRUB's root.

Install the GRUB bootloader (to the master boot record, sda in our example).

Tip: For more details, see the GRUB wiki page.

H: Reboot

That's it; You have configured and installed your Arch Linux base system. Exit the install, and reboot:

# reboot

(Be sure to remove the installer CD)

Part II: Configure & Update the New Arch Linux base system

Your new Arch Linux system will boot up and finish with a login prompt (you may want to change the boot order in your BIOS back to booting from hard disk).

Congratulations, and welcome to your new Arch Linux base system!

Your new Arch Linux base system is now a functional GNU/Linux environment ready for customization. From here, you may build this elegant set of tools into whatever you wish or require for your purposes.

Login with the root account. We will configure pacman and update the system as root, then add a normal user.

Note: Virtual consoles 1-6 are available. You may switch between them with ALT+F1...F6

Step 1: Configuring the network (if necessary)

  • This section will assist you in configuring most types of networks, if your network configuration is not working for you.

If you properly configured your system, you should have a working network. Try to ping www.google.com to verify this.

# ping -c 3 www.google.com

If you have successfully established a network connection, continue with Update, Sync, and Upgrade the system with pacman.

If, after trying to ping www.google.com, an "unknown host" error is received, you may conclude that your network is not properly configured. You may choose to double-check the following files for integrity and proper settings:

/etc/rc.conf # Specifically, check your HOSTNAME= and NETWORKING section for typos and errors.

/etc/hosts # Double-check your format. (See above.)

/etc/resolv.conf # If you are using a static IP. If you are using DHCP, this file will be dynamically created and destroyed by default, but can be changed to your preference. (See Network.)

Tip: Advanced instructions for configuring the network can be found in the Network article.

Wired LAN

Check your Ethernet with

# ifconfig -a

All interfaces will be listed. You should see an entry for eth0, or perhaps eth1.

  • Static IP

If required, you can set a new static IP with:

# ifconfig eth0 <ip address> netmask <netmask> up 

and the default gateway with

# route add default gw <ip address of the gateway>

Verify that /etc/resolv.conf contains your DNS server and add it if it is missing. Check your network again with ping www.google.com. If everything is working now, adjust /etc/rc.conf as described above for static IP.

  • DHCP

If you have a DHCP server/router in your network try:

# dhcpcd eth0

If this is working, adjust /etc/rc.conf as described above, for dynamic IP.

Wireless LAN

  • Ensure the driver has created a usable interface:
# iwconfig
  • Bring the interface up with ifconfig <interface> up. e.g.:
# ifconfig wlan0 up
Note: If you get this error message: SIOCSIFFLAGS: No such file or directory it most certainly means your wireless chipset requires a firmware to function, which you forgot to install during package selection. See Does the Wireless Chipset require Firmware? and Select Packages.
  • Associate your wireless device with the access point you want to use. Depending on the encryption (none, WEP, or WPA), the procedure may differ. You need to know the name of the chosen wireless network (ESSID), e.g. 'linksys' in the following examples:
  • An example using a non-encrypted network:
# iwconfig wlan0 essid "linksys"
  • An example using WEP and a hexadecimal key:
# iwconfig wlan0 essid "linksys" key 0241baf34c
  • An example using WEP and an ASCII passphrase:
# iwconfig wlan0 essid "linksys" key s:pass1
  • Using WPA, the procedure requires a bit more work. Check WPA supplicant for more information and troubleshooting:
# wpa_passphrase linksys "secretpassphrase" > /etc/wpa_supplicant.conf
# wpa_supplicant -B -Dwext -i wlan0 -c /etc/wpa_supplicant.conf
  • Check you have successfully associated to the access point before continuing:
# iwconfig wlan0
  • Request an IP address with /sbin/dhcpcd <interface> . e.g.:
# dhcpcd wlan0
  • Ensure you can route using /bin/ping:
# ping -c 3 www.google.com

You should have a working network connection. For troubleshooting, check the detailed Wireless Setup page.

Analog Modem

To be able to use a Hayes-compatible, external, analog modem, you need to at least have the ppp package installed. Modify the file /etc/ppp/options to suit your needs and according to man pppd. You will need to define a chat script to supply your username and password to the ISP after the initial connection has been established. The manpages for pppd and chat have examples in them that should suffice to get a connection up and running if you're either experienced or stubborn enough. With udev, your serial ports usually are /dev/tts/0 and /dev/tts/1. Tip: Read Dialup without a dialer HOWTO.

Instead of fighting a glorious battle with the plain pppd, you may opt to install wvdial or a similar tool to ease the setup process considerably. In case you're using a so-called WinModem, which is basically a PCI plugin card working as an internal analog modem, you should indulge in the vast information found on the LinModem homepage.

ISDN

Setting up ISDN is done in three steps:

  1. Install and configure hardware
  2. Install and configure the ISDN utilities
  3. Add settings for your ISP

The current Arch stock kernels include the necessary ISDN modules, meaning that you will not need to recompile your kernel unless you're about to use rather odd ISDN hardware. After physically installing your ISDN card in your machine or plugging in your USB ISDN-Box, you can try loading the modules with modprobe. Nearly all passive ISDN PCI cards are handled by the hisax module, which needs two parameters: type and protocol. You must set protocol to '1' if your country uses the 1TR6 standard, '2' if it uses EuroISDN (EDSS1), '3' if you're hooked to a so-called leased-line without D-channel, and '4' for US NI1.

Details on all those settings and how to set them is included in the kernel documentation, more specifically in the isdn subdirectory, and available online. The type parameter depends on your card; a list of all possible types can be found in the README.HiSax kernel documentation. Choose your card and load the module with the appropriate options like this:

# modprobe hisax type=18 protocol=2

This will load the hisax module for my ELSA Quickstep 1000PCI, being used in Germany with the EDSS1 protocol. You should find helpful debugging output in your /var/log/everything.log file, in which you should see your card being prepared for action. Please note that you will probably need to load some USB modules before you can work with an external USB ISDN Adapter.

Once you have confirmed that your card works with certain settings, you can add the module options to your /etc/modprobe.conf:

alias ippp0 hisax
options hisax type=18 protocol=2

Alternatively, you can add only the options line here, and add hisax to your MODULES array in the rc.conf. It's your choice, really, but this example has the advantage that the module will not be loaded until it's really needed.

That being done, you should have working, supported hardware. Now you need the basic utilities to actually use it!

Install the isdn4k-utils package, and read the manpage to isdnctrl; it'll get you started. Further down in the manpage you will find explanations on how to create a configuration file that can be parsed by isdnctrl, as well as some helpful setup examples. Please note that you have to add your SPID to your MSN setting separated by a colon if you use US NI1.

After you have configured your ISDN card with the isdnctrl utility, you should be able to dial into the machine you specified with the PHONE_OUT parameter, but fail the username and password authentication. To make this work add your username and password to /etc/ppp/pap-secrets or /etc/ppp/chap-secrets as if you were configuring a normal analogous PPP link, depending on which protocol your ISP uses for authentication. If in doubt, put your data into both files.

If you set up everything correctly, you should now be able to establish a dial-up connection with

# isdnctrl dial ippp0

as root. If you have any problems, remember to check the logfiles!

DSL (PPPoE)

These instructions are relevant to you only if your PC itself is supposed to manage the connection to your ISP. You do not need to do anything but define a correct default gateway if you are using a separate router of some sort to do the grunt work.

Before you can use your DSL online connection, you will have to physically install the network card that is supposed to be connected to the DSL-Modem into your computer. After adding your newly installed network card to the modules.conf/modprobe.conf or the MODULES array, you should install the rp-pppoe package and run the pppoe-setup script to configure your connection. After you have entered all the data, you can connect and disconnect your line with

# /etc/rc.d/adsl start

and

# /etc/rc.d/adsl stop

respectively. The setup usually is rather easy and straightforward, but feel free to read the manpages for hints. If you want to automatically 'dial in' at boot, add adsl to your DAEMONS array, and put a ! before the network entry, since the network is handled by adsl now.

Step 2: Update, Sync, and Upgrade the system with pacman

Now we will update the system using pacman.

What is pacman ?

Pacman is the package manager of Arch Linux. Pacman is written in C and is designed from the ground up to be lightweight, to occupy a very modest memory footprint, and to be fast, simple, and versatile. It manages your entire package system and handles installation, removal, package downgrade (through cache), custom compiled package handling, automatic dependency resolution, remote and local searches and much more. Pacman's output is streamlined, very readable and provides ETA for each package download. Arch uses pkg.tar.gz tarballs and is in the process of moving to the pkg.tar.xz format.

Pacman will now be used to download software packages from remote repositories and install them onto your system.

Package Repositories and /etc/pacman.conf

Arch currently offers the following 4 repositories readily accessible through pacman:

[core]

The simple principle behind [core] is to provide only one of each necessary tool for a base Arch Linux system; The GNU toolchain, the Linux kernel, one editor, one command line browser, etc. (There are a few exceptions to this. For instance, both vi and nano are provided, allowing the user to choose one or both.) It contains all the packages that MUST be in perfect working order to ensure the system remains in a usable state. These are the absolute system-critical packages.

  • Developer maintained
  • All binary packages
  • pacman accessible
  • The Core installation media simply contains an installer script, and a snapshot of the core repository at the time of release.

[extra]

The [extra] repository contains all Arch packages that are not themselves necessary for a base Arch system, but contribute to a more full-featured environment. X, KDE, and Apache, for instance, can be found here.

  • Developer maintained
  • All binary packages
  • pacman accessible

[testing]

The [testing] repository contains packages that are candidates for the [core] or [extra] repositories. New packages go into [testing] if:

* they are expected to break something on update and need to be tested first.

* they require other packages to be rebuilt. In this case, all packages that need to be rebuilt are put into [testing] first and when all rebuilds are done, they are moved back to the other repositories.

  • Developer maintained
  • All binary packages
  • pacman accessible
Note: [testing] is the only repository that can have name collisions with any of the other official repositories. Therefore, if enabled, [testing] must be the first repo listed in pacman.conf.
Warning: Only experienced users should use [testing].

[community]

The [community] repository is maintained by the Trusted Users (TUs) and is simply the binary branch of the Arch User Repository (AUR). It contains binary packages which originated as PKGBUILDs from AUR [unsupported] that have acquired enough votes and were adopted by a TU. Like all repos listed above, [community] may be readily accessed by pacman.

  • TU maintained
  • All binary packages
  • pacman accessible

AUR (unsupported)

The AUR also contains the unsupported branch, which cannot be accessed directly by pacman*. AUR [unsupported] does not contain binary packages. Rather, it provides more than sixteen thousand PKGBUILD scripts for building packages from source, that may be unavailable through the other repos. When an AUR unsupported package acquires enough popular votes, it may be moved to the AUR [community] binary repo, if a TU is willing to adopt and maintain it there.

  • TU maintained
  • All PKGBUILD bash build scripts
  • Not pacman accessible by default

* pacman wrappers (AUR Helpers) can help you seamlessly access AUR.

/etc/pacman.conf

pacman will attempt to read /etc/pacman.conf each time it is invoked. This configuration file is divided into sections, or repositories. Each section defines a package repository that pacman can use when searching for packages. The exception to this is the options section, which defines global options.

Note that the defaults should work, so modifying at this point may be unnecessary, but verification is always recommended. Further info available in the Mirrors article.

# nano /etc/pacman.conf

Example:

#
# /etc/pacman.conf
#
# See the pacman.conf(5) manpage for option and repository directives

#
# GENERAL OPTIONS
#
[options]
# The following paths are commented out with their default values listed.
# If you wish to use different paths, uncomment and update the paths.
#RootDir     = /
#DBPath      = /var/lib/pacman/
#CacheDir    = /var/cache/pacman/pkg/
#LogFile     = /var/log/pacman.log
HoldPkg     = pacman glibc
# If upgrades are available for these packages they will be asked for first
SyncFirst   = pacman
#XferCommand = /usr/bin/wget --passive-ftp -c -O %o %u
#XferCommand = /usr/bin/curl %u > %o

# Pacman won't upgrade packages listed in IgnorePkg and members of IgnoreGroup
#IgnorePkg   =
#IgnoreGroup =

#NoUpgrade   =
#NoExtract   =

# Misc options (all disabled by default)
#NoPassiveFtp
#UseSyslog
#ShowSize
#UseDelta
#TotalDownload
#
# REPOSITORIES
#   - can be defined here or included from another file
#   - pacman will search repositories in the order defined here
#   - local/custom mirrors can be added here or in separate files
#   - repositories listed first will take precedence when packages
#     have identical names, regardless of version number
#   - URLs will have $repo replaced by the name of the current repo
#
# Repository entries are of the format:
#       [repo-name]
#       Server = ServerName
#       Include = IncludePath
#
# The header [repo-name] is crucial - it must be present and
# uncommented to enable the repo.
# 

# Testing is disabled by default.  To enable, uncomment the following
# two lines.  You can add preferred servers immediately after the header,
# and they will be used before the default mirrors.
#[testing]
#Include = /etc/pacman.d/mirrorlist

[core]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/mirrorlist

[extra]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/mirrorlist 

[community]
# Add your preferred servers here, they will be used first
Include = /etc/pacman.d/mirrorlist

# An example of a custom package repository.  See the pacman manpage for
# tips on creating your own repositories.
#[custom]
#Server = file:///home/custompkgs

Enable all desired repositories (remove the # in front of the 'Include =' and '[repository]' lines).


  • When choosing repos, be sure to uncomment both the repository header lines in [brackets] as well as the 'Include =' lines. Failure to do so will result in the selected repository being omitted! This is a very common error.

/etc/pacman.d/mirrorlist

Defines pacman repository mirrors and priorities.

Build a mirrorlist using the rankmirrors script (Optional)

/usr/bin/rankmirrors is a python script which will attempt to detect uncommented mirrors specified in /etc/pacman.d/mirrorlist which are closest to the installation machine based on latency. Faster mirrors will dramatically improve pacman performance, and the overall Arch Linux experience. This script may be run periodically, especially if the chosen mirrors provide inconsistent throughput and/or updates. Note that rankmirrors does not test for throughput. Tools such as wget or rsync may be used to effectively test for mirror throughput after a new /etc/pacman.d/mirrorlist has been generated.

Initially force pacman to refresh the package lists

Issue the following command:

# pacman -Syy

Passing two --refresh or -y flags forces pacman to refresh all package lists even if they are considered to be up to date. Issuing pacman -Syy whenever a mirror is changed, is good practice and will avoid possible headaches.

Use pacman to install curl:

# pacman -S curl
  • If you get an error at this step, use the command "nano /etc/pacman.d/mirrorlist" and uncomment a server that suits you.

cd to the /etc/pacman.d/ directory:

# cd /etc/pacman.d

Backup the existing /etc/pacman.d/mirrorlist:

# cp mirrorlist mirrorlist.backup

Edit mirrorlist.backup and uncomment all mirrors on the same continent or within geographical proximity to test with rankmirrors.

# nano mirrorlist.backup

Run the script against the mirrorlist.backup with the -n switch and redirect output to a new /etc/pacman.d/mirrorlist file:

# rankmirrors -n 6 mirrorlist.backup > mirrorlist

-n 6: rank the 6 closest mirrors

Force pacman to refresh all package lists with the new mirrorlist in place:

# pacman -Syy

Mirrorcheck for up-to-date packages

Some of the official mirrors may contain packages that are out-of-date. ArchLinux Mirrorcheck reports various aspects about the mirrors such as, those experiencing network problems, data collection problems, reports the last time they have been synced, etc.

One may wish to manually inspect the mirrors in the /etc/pacman.d/mirrorlist insuring that it only contains up-to-date mirrors if having the latest package versions is a priority.

Ignoring packages

After executing the command "pacman -Syu", the entire system will be updated. It is possible to prevent a package from being upgraded. A typical scenario would be a package for which an upgrade may prove problematic for the system. In this case, there are two options; indicate the package(s) to skip in the pacman command line using the --ignore switch (do pacman -S --help for details) or permanently indicate the package(s) to skip in the /etc/pacman.conf file in the IgnorePkg array. List each package, with one intervening space :

IgnorePkg = wine  

The typical way to use Arch is to use pacman to install all packages unless there is no package available, in which case ABS may be used. Many user-contributed package build scripts are also available in the AUR.

The power user is expected to keep the system up to date with pacman -Syu, rather than selectively upgrading packages. You may diverge from this typical usage as you wish; just be warned that there is a greater chance that things will not work as intended and that it could break your system. The majority of complaints happen when selective upgrading, unusual compilation or improper software installation is performed. Use of IgnorePkg in /etc/pacman.conf is therefore discouraged, and should only be used sparingly, if you know what you are doing.

Ignoring Configuration Files

In the same vein, you can also "protect" your configuration/system files from being overwritten during "pacman -Su" using the following option in your /etc/pacman.conf

NoUpgrade = etc/lilo.conf boot/grub/menu.lst

Get familiar with pacman

pacman is the Arch user's best friend. It is highly recommended to study and learn how to use the pacman(8) tool. Try:

$ man pacman

For more information,please look up the pacman wiki entries at your leisure.

Step 3: Update System

You are now ready to upgrade your entire system. Before you do, read through the news (and optionally the announce mailing list). Often the developers will provide important information about required configurations and modifications for known issues. Consulting these pages before any upgrade is good practice.

Sync, refresh, and upgrade your entire new system with:

# pacman -Syu

or:

# pacman --sync --refresh --sysupgrade

pacman will now download a fresh copy of the master package list from the server(s) defined in pacman.conf(5) and perform all available upgrades. (You may be prompted to upgrade pacman itself at this point. If so, say yes, and then reissue the pacman -Syu command when finished.)

Reboot if a kernel upgrade has occurred.

Note: Occasionally, configuration changes may take place requiring user action during an update; read pacman's output for any pertinent information.

Pacman output is saved in /var/log/pacman.log.

See Package Management FAQs for answers to frequently asked questions regarding updating and managing your packages.

The Arch rolling release model

Keep in mind that Arch is a rolling release distribution. This means there is never a reason to reinstall or perform elaborate system rebuilds to upgrade to the newest version. Simply issuing pacman -Syu periodically keeps your entire system up-to-date and on the bleeding edge. At the end of this upgrade, your system is completely current. Reboot if a kernel upgrade has occurred.

Network Time Protocol

You may wish to set the system time now using NTP protocol to sync the local clock to remote NTP servers. There are two options available:

  • NTPD functions very well, though initial configuration may be more complex.
  • OpenNTPD is an alternative OpenBSD NTP project which is more simple to configure. Development may not be active for GNU/Linux at this time, as the last released version was on 14 May 2006.

For more information see the Network Time Protocol article.

Step 4: Add a user and setup groups

UNIX is a multi-user environment. You should not do your everyday work using the root account. It is more than poor practice; it is dangerous. Root is for administrative tasks. Instead, add a normal, non-root user account using the /usr/sbin/adduser program, an interactive user adding program which will prompt you for the relevant data (see details below) (recommended for beginners):

# adduser

Alternative method, using /usr/sbin/useradd:

Alternatively, you may use useradd

# useradd -m -G [groups] -s [login_shell] [username] 
  • -m Creates user home directory as /home/username. Within their home directory, a user can write files, delete them, install programs, etc. Users' home directories shall contain their data and personal configuration files, the so-called 'dot files' (their name is preceded by a dot), which are 'hidden'. (To view dotfiles, enable the appropriate option in your file manager or run ls with the -a switch.) If there is a conflict between user (under /home/username) and global configuration files, (usually under /etc/) the settings in the user file will prevail. Dotfiles likely to be altered by the end user include .xinitrc and .bashrc files. The configuration files for xinit and Bash respectively. They allow the user the ability to change the window manager to be started upon login and also aliases, user-specified commands and environment variables respectively. When a user is created, their dotfiles shall be taken from the /etc/skel directory where system sample files reside.
  • -G A list of supplementary groups which the user is also a member of. Each group is separated from the next by a comma, with no intervening spaces. The default is for the user to belong only to the initial group (users).
  • -s The path and filename of the user´s default login shell. Arch Linux init scripts use Bash. After the boot process is complete, the default login shell is user-specified. (Ensure the chosen shell package is installed if choosing something other than Bash).

Useful groups for your non-root user include:

  • audio - for tasks involving sound card and related software
  • floppy - for access to a floppy if applicable
  • lp - for managing printing tasks
  • optical - for managing tasks pertaining to the optical drive(s)
  • storage - for managing storage devices
  • video - for video tasks and hardware acceleration
  • wheel - for using sudo
  • power - used w/ power options (e.g.: shutdown with power button)

A typical desktop system example, adding a user named "archie" specifying bash as the login shell:

# useradd -m -G users,audio,lp,optical,storage,video,wheel,power -s /bin/bash archie

Next, add a password for your new user using /usr/bin/passwd.

An example for our user, 'archie':

# passwd archie

(You will be prompted to provide the new UNIX password.)

Your new non-root user has now been created, complete with a home directory and a login password.

Deleting the user account:

In the event of error, or if you wish to delete this user account in favor of a different name or for any other reason, use /usr/sbin/userdel:

# userdel -r [username]
  • -r Files in the user´s home directory will be removed along with the home directory itself and the user´s mail spool.

If you want to change the name of your user or any existing user, see the Change username page of the Arch wiki and/or the Groups and User Management articles for further information. You may also check the man pages for usermod(8) and gpasswd(8).

Step 5: Install and setup Sudo (Optional)

Install Sudo:

# pacman -S sudo

To add a user as a sudo user (a "sudoer"), the visudo command must be run as root.

By default, the visudo command uses the editor vi. If you do not know how to use vi, you may set the EDITOR environment variable to the editor of your choice, such as in this example with the editor "nano":

# EDITOR=nano visudo
Note: Please note that you are setting the variable and starting visudo on the same line at the same time. This will not work properly as two separated commands.

If you are comfortable using vi, issue the visudo command without the EDITOR=nano variable:

# visudo

This will open the file /etc/sudoers in a special session of vi. visudo copies the file to be edited to a temporary file, edits it with an editor, (vi by default), and subsequently runs a sanity check. If it passes, the temporary file overwrites the original with the correct permissions.

Warning: Do not edit /etc/sudoers directly with an editor; Errors in syntax can cause annoyances (like rendering the root account unusable). You must use the visudo command to edit /etc/sudoers.

To give the user full root privileges when he/she precedes a command with "sudo", add the following line:

USER_NAME   ALL=(ALL) ALL

where USER_NAME is the username of the individual.

For more information, such as sudoer <TAB> completion, see Sudo

Part III: Install X and configure ALSA

Step 1: Configure sound with alsamixer

The Advanced Linux Sound Architecture (known by the acronym ALSA) is a Linux kernel component intended to replace the original Open Sound System (OSS) for providing device drivers for sound cards. Besides the sound device drivers, ALSA also bundles a user space library for application developers who want to use driver features with a higher level API than direct interaction with the kernel drivers.

Note: Alsa is included in the Arch mainline kernel and udev will automatically probe your hardware at boot, loading the corresponding kernel module for your audio card. Therefore, your sound should already be working, but upstream sources mute all channels by default.
Note: OSS4.1 has been released under a free license and is generally considered a significant improvement over older OSS versions. If you have issues with ALSA, or simply wish to explore another option, you may choose OSS4.1 instead. Instructions can be found in OSS

The alsa-utils package contains the alsamixer userspace tool, which allows configuration of the sound device from the console or terminal.

By default the upstream kernel sources ship with snd_pcsp, the alsa pc speaker module. snd_pcsp is usually loaded before your "actual" sound card module. In most cases, it will be more convenient if this module is loaded last, as it will allow alsamixer to correctly control the desired sound card.

To have snd_pcsp load last, add the following to /etc/modprobe.d/modprobe.conf:

options snd-pcsp index=2

Alternatively, if you do not want snd_pcsp to load at all, blacklist it by adding the following to /etc/rc.conf:

MODULES=(... !snd_pcsp)
Note: You will need to unload all your sound modules and reload them for the changes to take effect. It might be easier to reboot. Your choice.

Install the alsa-utils package:

 # pacman -S alsa-utils

Also, you may want to install the alsa-oss package, which wraps applications written for OSS in a compatibility library, allowing them to work with ALSA. To install the alsa-oss package:

# pacman -S alsa-oss   

Did you add your normal user to the audio group? If not, use /usr/bin/gpasswd. As root do:

# gpasswd -a yourusername audio

As normal, non-root user, invoke /usr/bin/alsamixer:

# su - yourusername 
$ alsamixer

Unmute the Master and PCM channels by scrolling to them with cursor left/right and pressing M. Increase the volume levels with the cursor-up key. (70-90 Should be a safe range.) Some machines, (like the Thinkpad T61), have a Speaker channel which must be unmuted and adjusted as well. Leave alsamixer by pressing ESC.

Sound test

Ensure your speakers are properly connected, and test your sound configuration as normal user using /usr/bin/aplay:

$ aplay /usr/share/sounds/alsa/Front_Center.wav

You should hear a woman's voice saying, "Front, center."

Saving the Sound Settings

Switch back to root user and store these settings using /usr/sbin/alsactl :

# alsactl store

This will create the file '/etc/asound.state', saving the alsamixer settings.

Also, add the alsa daemon to your DAEMONS section in /etc/rc.conf to automatically restore the mixer settings at boot.

# nano /etc/rc.conf
DAEMONS=(syslog-ng network crond alsa)
Note: The alsa daemon merely restores your volume mixer levels on boot up by reading /etc/asound.state. It is separate from the alsa audio library (and kernel level API).

Expanded information available in the ALSA wiki entry.

Step 2: Install X

The X Window System version 11 (commonly X11, or just simply X) is a networking and display protocol which provides windowing on bitmap displays. It provides the standard toolkit and protocol to build graphical user interfaces (GUIs) on UNIX-like operating systems.

X provides the basic framework, or primitives, for building GUI environments: drawing and moving windows on the screen and interacting with a mouse and/or keyboard. X does not mandate the user interface — individual client programs handle this.

X is so named because it was preceded by the W Window System, originally developed at Stanford University.

A: The X-Files

Now we will install the base Xorg packages using pacman. This is the first step in building a GUI. If you plan on using an open-source video driver, and need 3d acceleration, install the libgl library before installing Xorg:

# pacman -S libgl

(Proprietary video drivers provide their own gl library implementations.)

Install the base packages:

# pacman -S xorg

The 3d utilities glxgears and glxinfo are included in the mesa package:

# pacman -S mesa

B: Install Video Driver Package

Now we have the base packages we need for running the X Server. You should add the driver for your graphics card now (e.g. xf86-video-<name>). The easiest way to configure X.org is by installing the correct driver packages first, and then generating /etc/X11/xorg.conf using an autoconfiguration script, like Xorg -configure.

You will need knowledge of which video chipset your machine has. If you do not know, use the /usr/sbin/lspci program:

# lspci | grep VGA

If you need a list of all open-source video drivers, do:

# pacman -Ss xf86-video | less

Here is a list of open source drivers, and the corresponding video chipsets.

  • xf86-video-apm — Alliance ProMotion video driver
  • xf86-video-ark — ark video driver
  • xf86-video-ati — ATI(AMD) radeon video driver
    • xf86-video-r128 — ATI(AMD) video driver for X.org ati Rage128 video
    • xf86-video-mach64 — ATI(AMD) video driver for X.org mach64 video
    • xf86-video-radeonhd — ATI(AMD) radeonhd video driver
  • xf86-video-chips — Chips and Technologies video driver
  • xf86-video-cirrus — Cirrus Logic video driver
  • xf86-video-dummy — dummy video driver
  • xf86-video-fbdev — framebuffer video driver
  • xf86-video-glint — GLINT/Permedia video driver
  • xf86-video-i128 — Number 0 i128 video driver
  • xf86-video-i740 — Intel i740 video driver
  • xf86-video-i810 — Intel i810/i830/i9xx video drivers (deprecated - use -intel)
  • xf86-video-intel — Newer Version of Intel i810/i830/i9xx video drivers
  • xf86-video-intel-legacy — Legacy-driver for older intel cards as 82865G (xf86-video-intel currently crashes with older cards)
  • xf86-video-imstt — Integrated Micro Solutions Twin Turbo video driver
  • xf86-video-mga — mga video driver (Matrox Graphics Adapter)
  • xf86-video-neomagic — neomagic video driver
  • xf86-video-nv — Nvidia nv video driver
  • xf86-video-nouveau — Open Source 3D acceleration driver for nVidia cards (experimental), check: [1] for Current Status
  • xf86-video-openchrome — VIA/S3G UniChrome, UniChrome Pro and Chrome9 video driver
  • xf86-video-rendition — Rendition video driver
  • xf86-video-s3 — S3 video driver
  • xf86-video-s3virge — S3 Virge video driver
  • xf86-video-savage — savage video driver
  • xf86-video-siliconmotion — siliconmotion video driver
  • xf86-video-sis — SiS video driver
  • xf86-video-sisusb — SiS USB video driver
  • xf86-video-tdfx — tdfx video driver
  • xf86-video-trident — Trident video driver
  • xf86-video-tseng — tseng video driver
  • xf86-video-unichrome — VIA S3 Unichrome video drivers
  • xf86-video-v4l — v4l video driver
  • xf86-video-vesa — vesa video driver
  • xf86-video-vga — VGA 16 color video driver
  • xf86-video-vmware — vmware video driver
  • xf86-video-voodoo — voodoo video driver

Note: The vesa driver is the most generic, and should work with almost any modern video chipset. If you cannot find a suitable driver for your video chipset, vesa should work.

Use pacman to install the appropriate video driver for your video card/onboard video. e.g.:

# pacman -S xf86-video-savage

(for the Savage driver.)

  • If you have an NVIDIA or ATI graphics card you may wish to install the proprietary NVIDIA or ATI drivers. Installing proprietary video drivers is covered below..
  • If you do not want to install the proprietary drivers or do not have an NVIDIA or ATI graphics card, you should skip down to C: Install Input Driver Packages.


NVIDIA Graphics Cards

The NVIDIA proprietary drivers are generally considered to be of good quality, and offer good 3D performance, whereas the open source nv driver offers only 2d support at this time and the new nouveau driver offers only experimental 3D acceleration.

Before you configure your Graphics Card you will need to know which driver fits. Arch currently has several different driver packages that each match a certain subset of Cards:

1. nvidia-96xx slightly newer cards up to the GF 4.

2. nvidia-173xx Geforce FX series cards

3. nvidia newest GPUs after the GF FX

Note: Nvidia-71xx series proprietary drivers, which are required by extremely old cards like TNT and TNT2, have been removed because they do not work with the new Xorg that Arch makes use of and nvidia has discontinued support for such. You should use the xf86-video-nv or xf86-video-vesa drivers instead.
Note: Currently Nvidia-173xx and -96xx drivers do not support Xorg release 1.8. Please see the news post here: [2].

Consult the NVIDIA website to see which one is for you. The difference is only for the installation; Configuration works the same with every driver.

Select and install the appropriate NVIDIA driver for your card, e.g.:

# pacman -S nvidia-96xx

Continue with C: Install Input Driver Packages.

ATI Graphics Cards

ATI owners have multiple options for drivers.

  • The open source radeon driver provided by the xf86-video-ati package.
    • This is the original, reverse-engineered open source driver which fully supports Radeon chipsets up to X1950 (latest R500 chipsets). Cards up to the 9200 series are fully supported, stable, and provide full 2D and 3D acceleration. Cards from 9500 to X1950 feature full 2D acceleration, and stable 3D acceleration, but lack certain features provided by the proprietary driver, (for example, powersaving is still in a testing phase). Cards from HD2xxx (R6xx) to the newest are supported by xf86-video-ati, but only offer 2d support at this time.
  • The open source radeonhd driver provided by the xf86-video-radeonhd package.
    • This driver supports ATI R500 chipsets (Radeon X1000 series) and newer. It is written by Novell with specifications provided to the public by AMD. It supports RandR 1.2 and development is currently very active. Therefore, functionality may be inconsistent across the spectrum of cards supported. (Some users report excellent performance and reliability while others experience trouble.) It also supports HDMI, with sound.
  • The proprietary fglrx driver provided by the Catalyst package located in the AUR. The proprietary driver is covered below.

The open-source drivers will usually suit most needs and are generally less problematic.

Install the radeon ATI Driver with

# pacman -S xf86-video-ati libgl ati-dri

Install the radeonhd ATi Driver with

# pacman -S xf86-video-radeonhd libgl ati-dri

The proprietary ATI driver Catalyst was once a precompiled package offered by Arch in the extra repository, but as of March 2009, official support has been dropped because of dissatisfaction with the quality and speed of development of the proprietary driver.The catalyst driver is now available in AUR. Installation information for Catalyst driver is available here

Warning: The proprietary ATI driver supports only R600 and newer devices (that means, HD2xxx and newer). Older series cards (X1xxx and older) are not supported.
Tip: Advanced instructions for ATI configuration can be found in the ATI wiki article.

C: Install Input Driver Packages

The latest X requires you to install drivers for your input devices, keyboard and mouse included. For a complete list of available input drivers, invoke a pacman search:

# pacman -Ss xf86-input | less

For most users, xf86-input-keyboard and xf86-input-mouse should be sufficient for a basic setup. Use pacman to install your desired drivers for your input devices. e.g.:

# pacman -S xf86-input-keyboard xf86-input-mouse
Warning: Some users had some problems with xf86-input-keyboard and xf86-input mouse. If your mouse and keyboard doesn't work and X seems freezed try uninstalling. For more information read the following forum post [[3]]

Step 3: Configure X (Optional)

Note: Since X11R7.2 the X.Org X Server features autoconfiguration. Therefore, it can function without an xorg.conf file in many cases. If the autoconfiguration works satisfactorily and you do not need to specify special features such as aiglx, compositing and so forth, you may forgo creating an xorg.conf file and continue below with Input hotplugging.

A: Introduction to the config file :xorg.conf

/etc/X11/xorg.conf is the main configuration file for your X Window System, the foundation of your Graphical User Interface. It is a plain text file ordered into sections and subsections. Important sections are Files, InputDevice, Module, Monitor, Modes, Screen, Device, and ServerLayout. Sections can appear in any order and there may be more than one section of each kind, for example, if you have more than one monitor, or if your laptop has a trackpoint as well as a mouse.

Standard xorg.conf generation

Advanced users may wish to manually create their own xorg.conf file. You may also use the /usr/bin/Xorg program with the -configure option to generate a basic config file; As root, do:

# Xorg -configure

This will create a config file at /root/xorg.conf.new

Copy the file to /etc/X11/:

# cp /root/xorg.conf.new /etc/X11/xorg.conf
Alternative xorg.conf generation

Newer versions of the Xorg Server(>1.6) do not include the /usr/bin/xorgconfig or /usr/bin/xorgcfg scripts. If you run into problems generating/using an xorg.conf file, you might want to consider using this guide.

See the article on X.Org, section "Without xorg.conf".

  • Note that if you are in possession of a properly configured xorg.conf under another distribution and with the same Xorg version, you may easily copy it over to your current Arch system's /etc/X11/ directory.
Tip: For Intel graphics card, specific configuration may be necessary to get proper 2D or 3D performance, as stated in the Intel wiki article.

If you have a nvidia graphics card and chose to install the proprietary nvidia driver, you should configure it now. Otherwise jump to B: Input hotplugging

The NVIDIA package has a utility for creating (or updating an existing) /etc/X11/xorg.conf for use with the NVIDIA driver:

# nvidia-xconfig
Note: The script output will inform you of a method of testing the created file.

It also has several options which will further specify the contents and options of the xorg.conf file. For example,

# nvidia-xconfig --composite --add-argb-glx-visuals

For more detailed information, see nvidia-xconfig(1).

Some useful tweaking options in the Device section are (beware that these may not work on your system):

       Option          "RenderAccel" "true"
       Option          "NoLogo" "true"
       Option          "AGPFastWrite" "true"
       Option          "EnablePageFlip" "true"

If there are instances of DRI, ensure they are commented out:

#    Load        "dri"

Double check your /etc/X11/xorg.conf to make sure your default depth, horizontal sync, vertical refresh, and resolutions are acceptable.

Update kernel module dependencies using /sbin/depmod:

# depmod -a

(A reboot may be necessary.)

Tip: Advanced instructions for NVIDIA configuration can be found in the NVIDIA article.

B: Input hotplugging

Input hotplugging is supported since the 1.4 version of the X.Org X Server and enabled by default. When enabled, X will now utilize udev to allow for the hotplugging and removal of human interface devices without having to restart X.

Note: As of X.Org X Server 1.8, the hal daemon is no longer utilized for input hotplugging. Rather, udev is used. (Installed by default)

You must decide whether you will use input hotplugging (enabled by default), or disable it. Input hotplugging is convenient for many users, especially those with mobile machines like laptops and netbooks. Other users may wish to disable it in favor of manual or more static device configuration within /etc/xorg.conf.

Tip: See the article on Xorg input hotplugging for full details.
Using input hotplugging

Install the evdev input driver:

# pacman -S xf86-input-evdev

If you do not use a standard US keyboard you need to set the keyboard layout in the file /etc/X11/xorg.conf.d/10-evdev.conf like this:

Section "InputClass"
	Identifier "evdev keyboard catchall"
	MatchIsKeyboard "on"
	MatchDevicePath "/dev/input/event*"
	Driver "evdev"
	Option "XkbLayout" "be"
EndSection
Note: The XkbLayout key may differ from the keymap code you used with the km or loadkeys command. For instance, the uk layout corresponds to the key: gb.

Laptop users will also need the synaptics package to allow X to configure the touchpad:

# pacman -S xf86-input-synaptics
Tip: For instructions on fine tuning or troubleshooting touchpad settings, see the Touchpad Synaptics article.
Disable input hotplugging

Disabling input hotplugging will skip devices detected by udev and will use the keyboard/mouse configuration from /etc/X11/xorg.conf:

# nano /etc/X11/xorg.conf

add the following:

Section "ServerFlags"
    Option "AutoAddDevices" "False"
EndSection
Set the keyboard layout if not using a standard US keyboard

Add option lines in the "InputDevice" section of the /etc/X11/xorg.conf file specifying the keyboard layout and variant.

Example:

Option "XkbLayout" "be"
Option "XkbVariant" ""

Alternative method using the setxkbmap command:

# setxkbmap pl 

(with the proper keyboard layout instead of pl of course) should switch your keyboard layout in x. To make this permanent, add this command to /home/<youruser>/.xinitrc before starting the window manager (before command like exec startxfce4).

C: Test X

First, read the warning about input hotplugging in the previous section. At this point, you should have xorg installed, with a suitable video driver and an /etc/X11/xorg.conf configuration file, (unless you chose to attempt to use X without it which is perfectly acceptable). If you want to test your configuration quickly, to ensure your ability to successfully start X from the command line, before installing a complete desktop environment, you can do so by configuring ~/.xinitrc to invoke Xterm. Xterm is a simple terminal emulator which runs in the X Server environment; it is installed as part of the base xorg packages.

Prepare for the test by configuring ~/.xinitrc

One of the main functions of this file is to dictate what X Window client is invoked with the /usr/bin/startx and/or /usr/bin/xinit program on a per-user basis. (The startx script is merely a front end to the more versatile xinit command.) There are vast amounts of additional configurable specifications and commands that may also be added to ~/.xinitrc as you further customize your system.

Note: .xinitrc is a so-called 'dot' (.) file. Files in a UNIX filesystem which are preceded with a dot (.) are 'hidden', and will not show up with a regular 'ls' command, usually for the sake of keeping directories tidy. Dot files may be seen by issuing ls -a. The 'rc' denotes Run Commands and simply indicates that it is a configuration file. Since it controls how a program runs, it is (although historically incorrect) also said to stand for "Run Control".

startx/xinit will start the X server and clients. To determine the client to run, startx/xinit will first look to parse a .xinitrc file in the user's home directory. In the absence of file ~/.xinitrc, it defaults to the global xinitrc in the xinit library directory; /etc/X11/xinit/xinitrc, which defaults to using the TWM window manager. (Hence, if you invoke startx without a ~/.xinitrc file, a TWM session will start.) Further details in the .xinitrc wiki entry.

Switch to your normal, non-root user:

# su - yourusername
  • /etc/skel/ contains files and directories to provide sane defaults for newly created user accounts. The name skel is derived from the word skeleton, because the files it contains form the basic structure for users' home directories.
Note: This template file .xinitrc is available in the /etc/skel directory when the package xorg-xinit is installed.
  • Sample .xinitrc provided here

Copy the sample xinitrc file from /etc/skel/ to your home directory:

$ cp /etc/skel/.xinitrc ~/

Edit the file:

$ nano ~/.xinitrc

and add "exec xterm" so that it looks like this:

#!/bin/sh
#
# ~/.xinitrc
#
# Executed by startx (run your window manager from here)
#
# exec wmaker
# exec startkde
# exec icewm
# exec blackbox
# exec fluxbox
# exec openbox-session
#
exec xterm
Note: Be sure to have only one uncommented exec line in ~/.xinitrc for now.

Below, we shall edit this file again to specify the appropriate desktop environment/window manager of your choice.

Perform the test

Test your configurations by starting X as normal, non-root user, with:

$ startx

or

$ xinit

You should have an xterm session open up. You can test your keyboard and its layout in it. You may have to move your mouse around until it enters the xterm area before you see the mouse cursor or xterm responds to your keyboard.

If you prove a properly configured /etc/X11/xorg.conf by successfully running the test, you can be assured that your DE/WM of choice will work smoothly.

Exit Xterm with:

$ exit
Tip: Advanced instructions for Xorg configuration can be found in the Xorg article.


Note: As of Xorg 1.6, CTRL-Alt-Backspace has been deprecated and will not work to exit out of this test. A possible workaround is to switch to a different virtual console (CTRL-Alt-F2, for example) and then switch back to the console the test is running in (probably CTRL-Alt-F1). You will then be able to use CTRL-C to kill the X test. You can enable CTRL-Alt-Backspace by editing xorg.conf, as described here.

If the screen goes black, you may still attempt to switch to a different virtual console (CTRL-Alt-F2, for example), and login blindly as root, followed by <Enter>, followed by root's password followed by <Enter>.

You can attempt to kill the X server with /usr/bin/pkill:

# pkill X

If pkill does not work, reboot blindly with:

# reboot

or

# init 6
In case of errors

If you have problems starting X, you can look for errors in the /var/log/Xorg.0.log file, as well as in the console output of the virtual console from which X was started.

Also, if using /etc/X11/xorg.conf, inspect the config file:

# nano /etc/X11/xorg.conf

for the following issues:

  • The video driver may need to be specified. e.g.:
Section "Device"

       ...
       Driver  "savage"
       ...

EndSection
  • Horizontal sync and vertical refresh specs under section "Monitor" may need to be added:
Section "Monitor"
       Identifier   "Monitor0"
       VendorName   "Monitor Vendor"
       ModelName    "Monitor Model"
       HorizSync     30.0 - 130.0 # Safe for LCD's
       VertRefresh   50.0 - 100.0 # Safe for LCD's and most CRT's.
EndSection

(If these specs are unknown, consult the documentation of the computer monitor.)

  • Color depth can be specified under section "Screen":
Section "Screen"
       Identifier "Screen0"
       Device     "Card0"
       Monitor    "Monitor0"
       DefaultDepth 24

(Typically, this will be set to 24 for true color.)

  • Also add desired Modes to the "Display" subsection, at least under the Depth 24 header, e.g.:
 SubSection "Display"
               Viewport   0 0
               Depth     24
               Modes "1024x768" "800x600" "640x480"
  • Add the following section, if eye candy which requires the composite extension is desired:
Section "Extensions"
 	Option "Composite" "Enable"
EndSection

Try the config again, after modifying, by running:

# startx

or

# xinit

Part IV: Installing and configuring a Desktop Environment

While The X Window System provides the basic framework for building a graphical user interface (GUI), a Desktop Environment (DE), works atop and in conjunction with X, to provide a completely functional and dynamic GUI. A DE typically provides a window manager, icons, applets, windows, toolbars, folders, wallpapers, a suite of applications and abilities like drag and drop. The particular functionalities and designs of each DE will uniquely affect your overall environment and experience. Therefore, choosing a DE is a very subjective and personal decision. Choose the best environment for your needs.

If you desire a lighter, less demanding GUI to configure manually, you may choose to simply install a Window Manager, or WM. A WM controls the placement and appearance of application windows in conjunction with the X Window System but does NOT include such features as panels, applets, icons, applications, etc., by default.

Step 1: Install Fonts

At this point, you may wish to save time by installing visually pleasing, true type fonts, before installing a desktop environment/window manager. Dejavu and bitstream-vera are good, general-purpose font sets. You may also want to install the Microsoft font sets, which are especially popular on websites, and may be required for the proper function of Flash animations which feature text.

Install with:

# pacman -S ttf-ms-fonts ttf-dejavu ttf-bitstream-vera

Refer to Xorg Font Configuration for how to configure fonts.

Step 2: ~/.xinitrc (again)

As non-root user, edit your /home/username/.xinitrc to specify the DE you wish to use. This will allow you to use startx/xinit from the shell, in the future, to open your DE/WM of choice:

$ nano ~/.xinitrc

Uncomment or add the 'exec ..' line of the appropriate desktop environment/window manager. Some examples are below:

For the Xfce4 desktop environment:

 exec startxfce4 

For the KDE desktop environment:

 exec startkde

A startkde or startxfce4 command starts the KDE or Xfce4 desktop environment. This is exactly the same as entering:

$ xinit /usr/bin/startxfce4

or

$ xinit /usr/bin/startkde

from the shell prompt. Note that such a command does not finish until you logout of the DE. Normally the shell would wait for KDE to finish, then run the next command. The "exec" prefix to this command within the ~/.xinitrc file tells the shell that this is the last command, so the shell does not need to wait to run a subsequent command.

In the future, after the DE of choice is installed and if trouble with automounting is experienced, try using the following command in ~/.xinitrc instead. (Replace "startxfce4" with the command that is appropriate for your window manager/DE.)

exec ck-launch-session startxfce4

This will ensure the various environment variables are set correctly by starting a clean consolekit session. ConsoleKit is a framework for keeping track of the various users, sessions, and seats present on a system. It provides a mechanism for software to react to changes of any of these items or of any of the metadata associated with them. It works in conjunction with dbus, and other tools.

Remember to have only one uncommented exec line in your ~/.xinitrc for now.

Step 3: Install a Desktop Environment

Continue below, installing the DE/WM of your choice.

GNOME

About GNOME

The GNU Network Object Model Environment. The GNOME project provides two things: The GNOME desktop environment, an intuitive and attractive desktop for end-users, and the GNOME development platform, an extensive framework for building applications that integrate into the rest of the desktop.

Installation

Install the base GNOME environment with:

# pacman -S gnome

Additionally, you can install the extras:

# pacman -S gnome-extra

It's safe to choose all packages shown in the extra package.

Useful DAEMONS for GNOME

Recall from above that a daemon is a program that runs in the background, waiting for events to occur and offering services.

Some users prefer to use the hal daemon. The hal daemon, among other things, will assist in automating the mounting of disks, optical drives, and USB drives/thumbdrives for use in the GUI. The hal package is installed as a dependency along with GNOME, but must be invoked to become useful.

Warning: The FAM (File Alteration Monitor) daemon is obsolete; use Gamin instead, if possible. Gamin is a re-implementation of the FAM specification. It is newer, more actively maintained, and simpler to utilize:
# pacman -S gamin

You may want to install a graphical login manager. For GNOME, the gdm daemon is a good choice.

Note: gdm is in the gnome-extra group; if you have installed that already, this step is not necessary.

As root:

# pacman -S gdm

Start hal:

# /etc/rc.d/hal start

Add the desired daemons to your /etc/rc.conf DAEMONS section, so they will be invoked at boot (Note that gamin is not to be added to the DAEMONS array):

# nano /etc/rc.conf
DAEMONS=(syslog-ng network crond alsa dbus hal gdm)
Tip: If you prefer to log into the console and manually start X, exclude the gdm daemon.
Note: HAL relies on and will automatically start dbus. However, some users have reported a failure with networkmanager unless dbus is implicitly specified in the DAEMONS array. When adding dbus to the array, ensure it directly precedes HAL.

Next, edit your /etc/gdm/custom.conf and in the [servers] section add:

0=Standard vt7

As normal user, start X:

$ startx

or

$ xinit

If ~/.xinitrc is not configured for GNOME, you may always start it with xinit, followed by the path to GNOME:

$ xinit /usr/bin/gnome-session
Tip: Advanced instructions for installing and configuring GNOME can be found in the Gnome article.

Congratulations! Welcome to your GNOME desktop environment on your new Arch Linux system. You may wish to continue by viewing General Recommendations, or the rest of the information below.

Eye Candy

By default, GNOME does not come with many themes and icons. You may wish to install some more attractive artwork for GNOME:

A nice gtk (gui widget) theme engine (includes themes) is the murrine engine. Install with:

# pacman -S gtk-engine-murrine

Optional for more themes:

# pacman -S murrine-themes-collection 

Once it has been installed, select it with System -> Preferences -> Appearance -> Theme tab.

The Arch Linux repositories also have a few more nice themes and engines. Install the following to see for yourself:

# pacman -S gtk-engines gtk-aurora-engine gtk-candido-engine gtk-rezlooks-engine

You can find many more themes, icons, and wallpapers at GNOME-Look.

Further Customization

See the Gnome ArchWiki page for useful details like adding passwordless login features for selected users and other useful information.

KDE

About KDE

The K Desktop Environment. KDE is a powerful Free Software graphical desktop environment for GNU/Linux and UNIX workstations. It combines ease of use, contemporary functionality, and outstanding graphical design with the technological superiority of UNIX-like operating systems.

Installation

Choose one of the following, then continue below with Useful KDE DAEMONS:

1. The package kde is the official and complete vanilla KDE 4.x residing under the Arch [extra] repo.

Install base kde:

# pacman -S kdebase-workspace

Install the whole Desktop Environment:

# pacman -S kde

or

# pacman -S kde-meta
Note: Learn about the difference between kde and kde-meta packages in the KDE Packages article.

2. Alternatively, another KDE project exists called KDEmod, part of the Chakra distribution. It is an Arch Linux (and spinoff) exclusive, community-driven package set designed for modularity and offers a choice between KDE 3.5.10 or 4.x.x. KDEmod can be installed with pacman, after adding the proper repositories to /etc/pacman.conf. The project website, including complete installation instructions, can be found at http://www.chakra-project.org/.

Gamin, an extension of the file alteration monitor (fam) project, is more actively developed than fam, and will be useful for reflecting real-time changes in the filesystem.

Install with:

# pacman -S gamin
Useful KDE DAEMONS

Recall from above that a daemon is a program that runs in the background, waiting for events to occur and offering services.

KDE will require the hal (Hardware Abstraction Layer) daemon for optimal functionality. The hal daemon, among other things, will facilitate the automatic mounting of disks, optical drives, and USB drives/thumbdrives for use in the GUI. The hal package is installed as a dependency along with KDE, but must be invoked to become useful.

The kdm daemon is the K Display Manager, which provides a graphical login, if desired.


Start hal:

# /etc/rc.d/hal start
Note: HAL relies on and will automatically start dbus. However, some users have reported a failure with NetworkManager unless dbus is implicitly specified in the DAEMONS array. When adding dbus to the array, ensure it directly precedes HAL.

Edit your DAEMONS array in /etc/rc.conf:

# nano /etc/rc.conf

Add dbus and hal to your DAEMONS array, to invoke it on boot. If you prefer a graphical login, add kdm as well:

DAEMONS=(syslog-ng dbus hal networkmanager alsa crond kdm)
  • This method will start the system at runlevel 3, (/etc/inittab default, multiuser mode), and then start KDM as a daemon.
  • Some users prefer an alternative method of starting a display manager like KDM on boot by utilizing the /etc/inittab method and starting the system at runlevel 5. See Display Manager for more.
  • If you prefer to log into the console at runlevel 3, and manually start X, leave out kdm, or comment it out with a bang, ( ! ).

Now try starting your X Server as normal user:

$ startx

or

$ xinit
Tip: Advanced instructions for installing and configuring KDE can be found in the KDE article.

Congratulations! Welcome to your KDE desktop environment on your new Arch Linux system! You may wish to continue by viewing General Recommendations, or the rest of the information below.

Eye candy

Arch KDE themes can be installed:

# pacman -S archlinux-themes-kde

Xfce

About Xfce

Xfce is another free software desktop environment for Linux. It aims to be fast and lightweight, while still being visually appealing and easy to use. Xfce is modular and reusable. It consists of separately packaged components that together provide the full functionality of the desktop environment, but which can be selected in subsets to create the user's preferred personal working environment. Xfce is mainly used for its ability to run a modern desktop environment on relatively modest hardware. It is based on the GTK+ 2 toolkit (the same as GNOME). It uses the Xfwm window manager, described below. Its configuration is entirely mouse-driven, and the configuration files are hidden from the casual user.

Installation

Install Xfce:

# pacman -S xfce4 

You may also wish to install themes and extras:

# pacman -S xfce4-goodies gtk2-themes-collection

Note: xfce4-xfapplet-plugin (a plugin that allows the use of GNOME applets in the Xfce4 panel) is part of the xfce4-goodies group and depends on gnome-panel, which in turn depends on gnome-desktop. You may wish to take this into consideration before installing, since it represents a significant number of extra dependencies.

To install the standard menu icons:

# pacman -S gnome-icon-theme

If you get errors about dbus-launch then you need to install dbus aswell:

# pacman -S dbus

If you wish to admire 'Tips and Tricks' on login, install the fortune-mod package:

# pacman -S fortune-mod
Useful DAEMONS

Recall from above that a daemon is a program that runs in the background, waiting for events to occur and offering services. Some Xfce users prefer to use the hal daemon. The hal daemon, among other things, will automate the mounting of disks, optical drives, and USB drives/thumbdrives for use in the GUI. The hal package is installed when you install Xfce, but must be invoked to become useful.

Note: fam (the file alteration monitor) is now obsolete. Install the gamin package but do not add gamin to rc.conf. gamin is automatically configured to run in the background by default.
# pacman -S gamin

Ensure hal is installed:

# pacman -Q hal

Start the hal daemon:

# /etc/rc.d/hal start
Note: HAL relies on and will automatically start dbus. However, some users have reported a failure with NetworkManager unless dbus is implicitly specified in the DAEMONS array. When adding dbus to the array, ensure it directly precedes HAL.

Edit your DAEMONS array in /etc/rc.conf:

# nano /etc/rc.conf

Add hal to your DAEMONS array, to invoke at boot.

Tip: Advanced instructions for installing and configuring Xfce can be found in the Xfce article.

If you wish to install one, see Display Manager. Otherwise you can login in via the console and run:

 $ startxfce4

Congratulations! Welcome to your Xfce desktop environment on your new Arch Linux system! You may wish to continue by viewing General Recommendations, or the rest of the information below.

LXDE

About LXDE

LXDE, (for Lightweight X11 Desktop Environment), is a new project focused on providing a modern desktop environment which aims to be lightweight, fast, intuitive and functional while keeping system resource usage low. LXDE is quite different from other desktop environments, since each component of LXDE is a discrete and independent application, and each can be easily substituted by other programs. This modular design eliminates all unnecessary dependencies and provides more flexibility. Details and screenshots available at: http://lxde.org/

LXDE provides:

  1. The OpenBox windowmanager
  2. PCManFM File manager
  3. LXpanel system panel
  4. LXSession session manager
  5. LXAppearance GTK+ theme switcher
  6. GPicView image viewer
  7. Leafpad simple text editor
  8. XArchiver: Lightweight, fast, and desktop-independent gtk+-based file archiver
  9. LXNM (still under development): Lightweight network manager for LXDE supporting wireless connections

These lightweight and versatile tools combine for quick setup, modularity and simplicity.

Installation

Install LXDE with:

# pacman -S lxde gamin

Gamin is a file and directory monitoring tool designed to be a subset of the FAM. It runs on demand for programs that have support for it so does not require a daemon like fam does.

Add:

exec startlxde

to your ~/.xinitrc and start with startx or xinit

  • If you experience problems with Policykit or plan on running nm-applet, the following command should be used instead
exec ck-launch-session startlxde
Tip: Further information available at the LXDE wiki article.

Congratulations! Welcome to your LXDE desktop environment on your new Arch Linux system! You may wish to continue by viewing General Recommendations, or the rest of the information below.

*box

Fluxbox

Fluxbox is yet another windowmanager for X. It's based on the Blackbox 0.61.1 code. Fluxbox looks like blackbox and handles styles, colors, window placement and similar things exactly like blackbox (100% theme/style compability).

Install Fluxbox using

# pacman -S fluxbox fluxconf

If you use gdm/kdm a new fluxbox session will be automatically added. Otherwise, you should modify your user's .xinitrc and add this to it:

exec startfluxbox

Openbox

Openbox is a standards compliant, fast, light-weight, extensible window manager.

Openbox works with your applications, and makes your desktop easier to manage. This is because the approach to its development was the opposite of what seems to be the general case for window managers. Openbox was written first to comply with standards and to work properly. Only when that was in place did the team turn to the visual interface.

Openbox is fully functional as a stand-alone working environment, or can be used as a drop-in replacement for the default window manager in the GNOME or KDE desktop environments.

Install openbox using

# pacman -S openbox

Additional configuration tools are also available, if desired:

# pacman -S obconf obmenu

Once openbox is installed you will get a message to move menu.xml & rc.xml to ~/.config/openbox/ in your home directory:

# su - yourusername
$ mkdir -p ~/.config/openbox/
$ cp /etc/xdg/openbox/rc.xml ~/.config/openbox/
$ cp /etc/xdg/openbox/menu.xml ~/.config/openbox/

rc.xml is the main configuration file for OpenBox. It may be manually edited, (or you can use OBconf). menu.xml configures the right-click menu.

You may log into OpenBox via graphical login using KDM/GDM, or from the shell using startx, in which case you will need to edit your ~/.xinitrc (as non-root user) and add the following:

exec openbox-session

NOTE: If you plan on running dbus (which is required by hal) then make sure your ~/.xinitrc reads:

exec dbus-launch --exit-with-session openbox-session

You may also start OpenBox from the shell using xinit:

$ xinit /usr/bin/openbox-session
  • Openbox may also be used as the window manager for GNOME, KDE, and Xfce.

For KDM there is nothing left to do; openbox is listed in the sessions menu in KDM.

Some useful, lightweight programs for OpenBox are:

  • PyPanel, Tint2, or LXpanel if you want a panel
  • feh if you want to set the background
  • ROX if you want a simple file manager (also provides simple icons)
  • PcmanFM a lightweight but versatile file manager (also provides desktop icon functionality)
  • iDesk (available in AUR) for providing desktop icons
  • Graveman for burning CD's or DVD's
Tip: More information is available in the Openbox article.

FVWM2

FVWM (F Virtual Window Manager) is an extremely powerful ICCCM-compliant multiple virtual desktop window manager for the X Window system. Development is active, and support is excellent.

Install fvwm2 with

# pacman -S fvwm 

It will install the official version of the WM. However, if you want/need to use some more features than it provides, you can install the patched version from the AUR (see package fvwm-patched) or from archlinuxfr (see Unofficial user repositories) using pacman:

# pacman -S fvwm-patched

fvwm will automatically be listed in kdm/gdm in the sessions menu. Otherwise, add

exec fvwm2 

to your user's .xinitrc.

When you start FVWM2, you will get into the blank configuration. However, when you left-click on the desktop, you will be able to select to configure FVWM. chose wanted modules and you are ready to go. Check out the configs in the http://www.box-look.org. One should also consider checking FVWM forums at http://fvwm.lair.be

SLiM is a very good login manager, that does not have many dependencies and acts well with FVWM. Common Applications are similar to those suggested for Openbox or Fluxbox.

Tiling WMs

In addition to floating window managers, there are also several tiling window managers available. This type of window manager may be described as making more extensive usage of the keyboard, less (or no) reliance on the mouse, and window control via predefined layouts. Windows are usually resized and positioned so that they would not overlap, potentially maximizing space.

Here are some of the more popular tiling WMs, in alphabetical order:

More information can be found in the Comparison of Tiling Window Managers article.

Multimedia

Codecs, plugins and Java

Multimedia codecs, plugins and Java can be installed with the following:

pacman -S mplayer gecko-mediaplayer xine-lib xine-ui libdvdread libdvdcss alsa-oss jre

Ensure the legality of using libdvdcss in your region before installing.
