The X201 is a 4-core subnotebook produced by Lenovo. See Thinkwiki for more information.

Arch installs and runs flawlessly. Some specials features need tweaks, though.

Drivers

Graphics are Intel-powered, so you will need the Intel driver xf86-video-intel for direct rendering.

Hibernation

To make hibernation work uswsusp is needed.

Fbsplash

To make fbsplash work, i915 has to be added to the modules array in mkinitcpio.conf:

/etc/mkinitcpio.conf
MODULES="i915"

Frequency Scaling

Use cpufrequtils to enable frequency scaling.

Bootloader kernel options

Add these kernel options to your bootloader's config file to make use of power saving mechanismens which are turned off by default because of reported instabilities. For me, they will work fine on the X201.

Warning: These options can cause instability on your system! Try them and remove them if you are experiencing problems.

grub2

/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="[...] i915_enable_rc6=1 i915_enable_fbc=1"

Update grub.cfg afterwards: grub-mkconfig -o /boot/grub/grub.cfg

grub1

Add the options above to /boot/grub/menu.lst.
