["Christopher M. Penalver" <christopher.m.penalver@xxxxxxxxx>]

Adam Niedling, as per http://us.acer.com/ac/en/US/content/drivers an
update is available for your BIOS (1.21). If you update to this
following https://help.ubuntu.com/community/BiosUpdate , does it change
anything?

If not, could you please both specify what happened, and provide the output of the following terminal command:
sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date

Please note your current BIOS is already in the Bug Description, so
posting this on the old BIOS would not be helpful.

For more on BIOS updates and linux, please see
https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette
.

Thank you for your understanding.

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.
