Title:
  10de:0a3c [HP EliteBook 8540w] Screen backlight changes automatically
  for no reason

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  When working on HP EliteBook 8540w the screen gets lighter (up to 100%
  brightness) and then darker (down to ~50% brightness). And it goes on
  and on. It's kind of annoying. I think it was not like that before
  upgrade to 11.10.

  I have the screen setting to dim the screen on inactivity turned off.
