Adam Niedling, if you disable the nvidia card in BIOS, and uninstall
bumblebee, does it allow you to adjust the brightness?

Title:
  Screen brightness adjust hotkeys don't work with an Acer 5755G laptop

Status in The Linux Kernel:
  Confirmed
Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I'm using Oneiric x64. When I press fn+left/right arrow keys the
  brightness of the screen doesn't change even thou the bar appears on
  the top right corner correctly. This laptop has two video cards:
  nVidia 540M and an integrated Intel HD Graphics 3000. Normally the
  nVidia card is switched off by Bumblebee so only the Intel one is
  running.
