The following tips come from someone running Gentoo on an Ultra5. This page is meant to help those with relatively specific problems as opposed to more general help - http://www.gentoo.org/proj/en/base/sparc/index.xml

Keyboard Maps

Every now and then after a huge emerge --update world you might notice your keyboard has become 'unmapped', which makes it next to impossible to correct on the same physical box.

  1. . You'll need access to a sane prompt: login from second system via SSH or use your gentoo install disk.
  2. . Disable XDM: rc-update del xdm
  3. . Reboot the machine

If your keymap is broken at the tty/mgetty level, investigate the KEYMAP setting in /etc/rc.conf. Here's what I'm using (as of March 20, 2005): 

KEYMAP="sunt5-us-cz" 
EXTENDED_KEYMAPS=

xorg-x11 is another challenge. Here's what I'm using: 

Section "InputDevice"
   Identifier  "Keyboard1"
   Option      "Protocol"   "standard"
   Driver      "Keyboard"
   Option      "AutoRepeat" "500 30"
   Option      "XkbRules"   "sun"
   Option      "XkbModel"   "type5"
EndSection

While we're at it, here's the entire xorg.conf.

2.4.x Kernel

Here's the config from the latest 2.4.29 sparc-sources. This is a static-only kernel, and is relatively stripped down. If you don't see an option then it's disabled (I've grep -v'd them for brevity). Build your kernel with make vmlinux, and strip useless symbols with strip -R .ident -R .comment -R .note vmlinux

2.6.x Kernel

Check out http://dev.gentoo.org/~ciaranm/docs/sparc-2.6.x/ for more help. <<-- THIS LINK IS DEAD. Someone who has a better idea? :)

I haven't got 2.6.x working with Xorg because I can't find the equivalent of ATI PCI Framebuffer Support. 

CONFIG_FB_PCI=y
CONFIG_FB_ATY=y
CONFIG_FB_ATY_CT=y

If you figure it out, please edit this area.
