Works with no known issues. The point releases "Voodoo" and "Don't Panic" work without problems.


Power Management

Suspend and Hibernate

Works flawlessly. See Suspend to Disk. Also known to work with Pm-utils.


An easy way is use "suspend to swap" by adding resume=/dev/disk/by-uuid/"your-swap-uuid" to the kernel line inside /boot/grub/menu.lst. find your "/dev/disk/by-uuid/" for the swap Partition by "/bin/ls -lF /dev/disk/by-uuid/" and put it behind "root=/dev/disk/by-uuid/"uuid" ". You can use it perfectly with gnome-power-manager.

Laptop Mode Tools

Works flawlessly. See Laptop Mode Tools.

CPU Frequency Scaling

Works as described in CPU Frequency Scaling with acpi-cpufreq as of 2.6.27-ARCH. Maybe you need to use speedstep-ich on earlier kernels.


They work better after loading the thinkpad-acpi module, to assign the generated keycodes to there supposed functions.

As of December 2007, they don't work properly, since HAL is messing around with it's improvements.


tpb (for Thinkpad Buttons) is available through pacman:

pacman -S tpb 

tpb adds an on-screen volume bar for the volume buttons, THINKPAD button assignment, on-screen messages for Thinklight, (on and off) and more.


Yes, this didn't work from the beginning for me, but here is the solution:

keycode 77 = Num_Lock 

Add that line to your ~/.xmodmap file.


Works fine with driver xf86-video-savage. Fancy eye-candy like composition won't work with this card.

Here is my by hand written configuration for X that _should_ work. But since the recent update with xorg-server 1.5, the keyboard and mouse management has changed somehow, which means, the InputDevice Sections are in a reason deprecated or something else. Please refer to Xorg input hotplugging for further information.

Input detection on xorg-server 1.5 goes through hal, so start it before running X.

/etc/rc.d/hal start

Also add it to /etc/rc.conf

DAEMONS=(... hal ...)

Please not, if you've got an SXGA+, the graphics card won't support a higher depth than 16 as the memory can't house more colours.
