# Lenovo ThinkPad X220

From ArchWiki

## Setup

### Graphics

The graphic card is supported by the xf86-video-intel driver package from the extra repository. The Xorg server makes use of this automatically. There's no need for a Xorg configuration file.

    pacman -S xf86-video-intel

### Booting

The X220 cannot boot from a GPT disk with legacy BIOS, so either use an MBR disk or setup UEFI.

## Configuration

### Heat issues

According to a forum post you should set some power saving options in /etc/modprobe.d/modprobe.conf or add them to your kernel line in your menu.lst. We use rc6=7 for deepest sleep mode.

    options i915 modeset=1
    options i915 i915_enable_rc6=7
    options i915 i915_enable_fbc=1
    options i915 lvds_downclock=1

As well you could suffer of Kernel Power Regressions.

### My laptop gets stuck in a reboot loop if I resume from suspend! Help!

This can be caused by the EFI storage getting too full. Run the following commands as root to free up some space -

     # First clear the pstore
     mkdir -p /dev/pstore
     mount -t pstore pstore /dev/pstore
     ls /dev/pstore # <- Nothing important should be here, but check first anyway
     rm /dev/pstore/*

     # Next some EFI variables. These are used/created by pstore, but I've had them even though
     #I deleted the pstore data using the above commands. YMMV.
     rm /sys/firmware/efi/efivars/dump-type0-*
