Christopher: I'm not using Bumblebee anymore. I tried to disable the
nvidia card in BIOS but adjusting the brightness still does not work.
However the brightness bar got visible in the top right corner when I'm
trying to adjust it. There is no bar with the nvidia card enabled.

** Description changed:

- 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.
+ I'm using a freshly installed Saucy x64. When I press fn+left/right arrow keys the brightness of the screen doesn't change and there is no bar appearing on the top right corner indicating the change in brightness. 
+ This laptop has two video cards: nVidia 540M and an integrated Intel HD Graphics 3000.
+ If the nVidia card is disabled in BIOS the top right bar appears but the brightness still does not change.

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 a freshly installed Saucy x64. When I press fn+left/right arrow keys the brightness of the screen doesn't change and there is no bar appearing on the top right corner indicating the change in brightness.
  This laptop has two video cards: nVidia 540M and an integrated Intel HD Graphics 3000.
  If the nVidia card is disabled in BIOS the top right bar appears but the brightness still does not change.
