Title:
  [Lenovo ThinkPad X220] kernel 3.13 i915 brightness settings broken
  when going from docked -> undocked

Status in The Linux Kernel:
  New
Status in “linux” package in Ubuntu:
  Incomplete
Status in “linux” package in Fedora:
  Unknown

Bug description:
  This happens on my X220, running trusty, linux 3.13.0-24-generic. It's
  the exact same problem discussed on
  https://bugzilla.redhat.com/show_bug.cgi?id=1067071. Discussed also on
  kernel mailing list: https://lkml.org/lkml/2014/2/19/720. It worked on
  3.12, and upstream acknowledges the regression.

  To reproduce, remove the X220 from the dock. The brightness is set to
  minimum (the screen is nearly unreadable) and the brightness control
  is broken, you can't adjust it by hardware keys.

  My hardware:
  00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) (prog-if 00 [VGA controller])
   Subsystem: Lenovo Device 21da
   Kernel driver in use: i915
  Docked on a ThinkPad mini dock series 3.

  I have nothing much relevant in /var/log/syslog. Below there are
  excerpts of it when brightness is working:

  Apr 16 14:55:37 galactica kernel: [79261.217384] [drm:asle_set_backlight], bclp = 0x800000ff
  Apr 16 14:55:37 galactica kernel: [79261.217390] [drm:asle_set_backlight], updating opregion backlight 255/255
  Apr 16 14:55:37 galactica kernel: [79261.217394] [drm:intel_panel_get_max_backlight], max backlight PWM = 4648
  Apr 16 14:55:37 galactica kernel: [79261.217396] [drm:intel_panel_actually_set_backlight], set backlight PWM = 4590
  Apr 16 14:55:37 galactica kernel: [79261.217537] [drm:asle_set_pwm_freq], PWM freq is not supported

  And brightness not working:

  Apr 16 15:23:46 galactica kernel: [80948.263160] [drm:asle_set_backlight], bclp = 0x80000058
  Apr 16 15:23:46 galactica kernel: [80948.263168] [drm:asle_set_pwm_freq], PWM freq is not supported
  Apr 16 15:23:46 galactica kernel: [80948.280637] [drm:asle_set_backlight], bclp = 0x80000041
  Apr 16 15:23:46 galactica kernel: [80948.280642] [drm:asle_set_pwm_freq], PWM freq is not supported

  A workaround is to echo values directly to /sys/class/backlight/intel_backlight/brightness. Maximum brightness is 4648 (/sys/class/backlight/intel_backlight/max_brightness).
  e.g.: # echo 500 > /sys/class/backlight/intel_backlight/brightness
