Title:
  Unable to change brightness at all

Status in “linux” package in Ubuntu:
  Won't Fix

Bug description:
  Installed 12.04.2 on this system and performing certification tests.
  I tried changing the screen brightness using the brightness keys, the
  brightness and lock tool and using a test that directly dims the
  screen to 50% and returns  it to full.

  None of those methods worked and there is no way at all to change the
  brightness on this machine.

  Also, this is running the latest update kernel for 12.04.2
