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.


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


Install pm-utils and uswsusp and configure it as pm-util's backend. See Pm-utils#Using_another_sleep_back-end_.28like_uswsusp.29 for instructions.


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


Power Saving

Fan control

There are some discussions concerning overheating-related shutdowns when running under full load (video encoding, etc). Thinkpad Fan Control contains instructions to install tpfand as a custom replacement for bios fan control.

Warning: Wrong settings may damage your machine! Use with caution!

After that, start tpfan-admin and adjust the settings (by clicking on the sensor's graph). You should split the graph (via context menu) and set the fan to full-speed when the sensor reaches, say, 65 °C. You may also edit the config file directly.


You may install TLP instead of Laptop Mode Tools to automate power saving operations.

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.


GRUB_CMDLINE_LINUX_DEFAULT="[...] i915_enable_rc6=1 i915_enable_fbc=1"

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


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