[edit] Frame Buffer

The rage128 frame buffer doesn't seem to work - it just looked like it was melting the monitor. vesa-tng works well though, as long as you don't pass it any boot options. Compile it in, and do not pass it any video=soandso options in grub.conf, and you'll have a nice high resolution view of green [OK]'s going by at boot.

Update by Yamakuzure (March, 20th, 2007)
With kernel 2.6.19-gentoo-r5 it works great with "ATI Rage128 Display support" compiled into the kernel (aty128fb <-- the "y" is correct!) and the following option in grub.conf:

[edit] Setting up DRI

Believe it or not, this little laptop can churn out almost 800fps in glxgears, at 1024 x 768 x 16bits. No trial and error xorg.conf guessing either, because this other fella posted a flawless xorg.conf. I just followed his advice for the graphics setup and copied his xorg.conf to /etc/X11/xorg.conf and whammo, 3d acceleration.

Thu Jul 26th 18:32 CST The above link to "xorg.conf" seems to be broken.

Update, April 08th, 2007 by Yamakuzure
If you want to use Suspend-to-Ram or Suspend-to-Disk, you have to disable the DRI Module, or your notebook won't wake up properly. The r128 driver can not be reactivated properly while DRI is enabled.
Maybe the driver/DRI get's updated in the future so it'll work, but for now it won't, at least with modular xorg 7.

[edit] Using the External VGA Connection

Plug a monitor into the VGA connector on the side of the laptop, and add the following line to your xorg.conf in the Device section:

Option "Display" "CRT"

You can also use "BIOS", see http://www.xfree86.org/current/r128.4.html for more detail on the Display option. You will also need to add configuration information for the external display to your xorg.conf.

[edit] APM

APM is working fairly well. Here is how it was done:

[edit] Update your BIOS.

This laptop had BIOS A03 on it when I got it. Dell has had 20 BIOS releases since then, and you will need them so that APM works properly. Before I updated the bios, the suspend button just crashed the system - monitor would freeze, and pressing the power button made the laptop reboot. Now it works just fine.

The latest bios version is A23. get it straight from Dell here.

If you're like me, there is no Windows system on your machine and you wonder how you are going to run that .exe file. I used this .iso file. According to diff the executable is the same as the one on the Dell FTP site. I burned it to CD on my desktop with cdrecord, using the options explained here. The command will look something like:

cdrecord -v dev=ATA:1,0,0 C600_A23.iso

now pop that CD in and reboot.

[edit] Set up your kernel

Here are my power options in the kernel configuration:

Linux Kernel Configuration: 2.6.15-gentoo-r1
Power management options (ACPI, APM) --->  
 [*] Power Management support                                           
 [*]   Legacy Power Management API     
 [ ] ACPI (Advanced Configuration and Power Interface) Support  --->
     APM (Advanced Power Management) BIOS Support  --->                                        
        <M> APM (Advanced Power Management) BIOS support            
        [*]   Enable PM at boot time                                  
        [*]   Make CPU Idle calls when idle                           
        [*]   Use real mode APM BIOS call to power off              

Add the APM module to your auto load list:

echo "apm" >> /etc/modules.autoload.d/kernel-2.6

[edit] apmd

Next, apmd is needed:

emerge apmd

As of writing , there is a bug with the apmd ebuild described here. if you have this trouble,

emerge libtool

and then try again:

emerge apmd

and add it too your environment.

rc-update add apmd default
/etc/init.d/apmd start

This sould get you going. Try suspending. There seem to be some problems: on occasion, USB mouse support is lost and/or DRM. Any tips here are welcome.

My solution to these little problems so far is to venture into ACPI.

[edit] ACPI

I've started looking into ACPI, because of certain quirks with APM. I'm probably just going to get into trouble and make do with APM, but i'm curious.

iasl -tc dsdt.dsl
Intel ACPI Component Architecture
ASL Optimizing Compiler version 20060127 [Apr 30 2006]
Copyright (C) 2000 - 2006 Intel Corporation
Supports ACPI Specification Revision 3.0a
dsdt.dsl   705:     Method (\_WAK, 1, NotSerialized)
Warning  2078 -                 ^ Reserved method must return a value (_WAK)

AML Output: DSDT.aml - 10277 bytes 393 named objects 699 executable opcodes
Compilation complete. 0 Errors, 1 Warnings, 0 Remarks, 340 Optimizations

Well i can't blame it on the dsdt.

A closer look at my kernel config revealed that sleep states where not enabled. So remember, kids, you must disable SMP in the processor before the sleep options will become avaiable. So now echo -n mem > /sys/power/state does something at least. The screen gets real bright and the computer get zombifoed. but hey, that's a little better than nothing. :) when finals are over i'll get this thing straightend out.

Well, thanks to [1] my machine now wakes up from both hibernate-mem and hibernate! The only thing left is to get this screen to turn itself off when hibernating... It's still getting all bright white and all.

Got it. thanks to the guys at #gentoo-laptop on freenode.

emerge acpid
emerge hibernate-script
emerge radeontool

then in /etc/hibernate/hibernate.conf and /etc/hibernate/mem.conf, uncomment this line:

use radeontool yes

now my backlight turns off on both suspend-ram and suspend-disk. to configure these events to happen when you shut the lid or push Fn-Suspend, see [TIP_ACPI_basic_configuration] or read the script comments in /etc/acpi.

[edit] NIC and modem

The nic works with the 3com kernel module 3c59x. No luck with the modem, though. I dont see anyone claiming to have gotten this one working. looks like it's a winmodem, not a linmodem. The sad part is, the NIC and the modem are on the same little expansion card. So you can't just swap out the modem. :-(

[edit] PCMCIA

Bus options (PCI, PCMCIA, EISA, MCA, ISA --->
    PCCARD (PCMCIA/CardBus) support  --->                   
    <M> PCCard (PCMCIA/CardBus) support                              
    [ ]   Enable PCCARD debugging                                    
    <M>   16-bit PCMCIA support                                      
    [ ]     Load CIS updates from userspace (EXPERIMENTAL)           
    [*]     PCMCIA control ioctl (obsolete)                          
    ---   32-bit CardBus support                                     
    ---   PC-card bridges                                            
    <M>   CardBus yenta-compatible bridge support                  

Turns out this card bridge is yenta-compatible. go figure. My kernel version is > 2.6.13, so i did:

emerge pcmciautils


emerge pcmcia-cs

i don't have any pcmcia cards to test this with right now, so i'll get back to you and let you know if it works when i pick up a wifi card.

[edit] Synaptics

This laptop also comes with a synaptics touchpad. I followed the Synaptics guide and used the preconfigured xorg from the 2006.1 live dvd. My xorg.conf has the following:

File: /etc/X11/xorg.conf
Section "ServerLayout"
   InputDevice     "Keyboard0" "CoreKeyboard"
   InputDevice     "USB Mouse" "AlwaysCore"
   InputDevice     "Synaptics" "AlwaysCore"

Section "InputDevice"
    Identifier      "Synaptics"
    Driver  "synaptics"
    Option  "Protocol" "event"
    Option  "Device" "/dev/input/event1"
    Option  "LeftEdge" "1900"
    Option  "RightEdge" "5400"
    Option  "TopEdge" "1900"
    Option  "BottomEdge" "4000"
    Option  "FingerLow" "25"
    Option  "FingerHigh" "30"
    Option  "MaxTapTime" "180"
    Option  "MaxTapMove" "220"
    Option  "VertScrollDelta" "100"
    Option  "MinSpeed" "0.02"
    Option  "MaxSpeed" "0.10"
    Option  "AccelFactor" "0.0010"
    Option  "SHMConfig" "on"

Some people seem to notice a problem with regards to mouse drift. This is a known hardware problem present on the Dell Latitude C600. It can be 'fixed' by using either of two methods; [METHOD 1] Remove the keyboard, locating the flat cable to the nipple, and cut it. Note that this means that you will not be able to use the nipple again, however, the touchpad still works. [METHOD 2] Follow the instructions given on this page http://www.laptopsunlimited.com/dellmouse/dellmouse.htm which shows how to overcome the hardware glitch by taking apart the laptop and inserting a plastic bag between two metal surfaces (the cause of the mouse drift). Giving you full functionality of both the touchpad and nipple.

[edit] Sound

Getting sound working is easy. The Card is a Maestro3. It shows up with lspci as: 00:08.0 Multimedia audio controller: ESS Technology ES1983S Maestro-3i PCI Audio Accelerator (rev 10)

Enable sound support in your kernel:
cd /usr/src/linux
make menuconfig
then go to:
Device-Drivers -> Sound -> Advanced Linux Sound Architecture -> PCI-Devices -> enable ESS Allegro/Maestro3
CONFIG_SND_MAESTRO3=y should then be set in your kernel .config
