Title:
  Thnikpad X220 - brightness control doesn't work

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  After upgrading to Ubuntu 14.10 brightness control no longer works on
  Lenovo Thinkpad X220. Fn+Home/Fn+End doesn't work, the only way is to
  echo value to:

  /sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-LVDS-1/intel_backlight/brightness

  I use Awesome WM, but it doesn't seem to be related to Awesome.
