Title:
  screen brightness unchangable

Status in xf86-video-intel:
  Invalid
Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: xorg

  Hello, I am using a Gateway NV5927U laptop and the screen brightness
  is unchangeable via the keyboard controls.  The brightness is stuck at
  100% and changing values inside of /proc/acpi/video/GFX0 have no
  effect on the brightness.  Please let me know what else you may need.
  If the brightness is changed inside of Microsoft Windows it will
  visually stay dim until GDM starts, at this point the screen raises to
  full brightness and is locked at that state.
