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. ** Tags added: bios-outdated-v1.21 needs-upstream-testing ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/925690 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.
