[Bug 1184775] Re: Unable to change screen's brightness

 

MichaelDel, as per
http://www.medion.com/gb/service/start/_product.php?msn=30010561&gid= an
update is available for your BIOS (10M). If you update to this, 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

Thank you for your understanding.

Title:
  Unable to change screen's brightness

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Hi
  I have just installed Ubuntu 12.04 LTS on my Medion Akoya P6613
  It has an Intel i3 390m and a NVIDIA geforce GT 540m
  When I change the brightness with the FN keys the brightness window pops up and also changes but the actual brightness of the display does not change. How can I fix this problem?
  What I have already done is checking for updates and following the instructions in this post: https://answers.launchpad.net/ubuntu/+question/211457
  but it didn't help
  could it be possible that it is a problem with the graphics card and if so, how can i possibly fix it?
  Michael

  after some help by community members i installed bumblebee and also changed the settings, but it did not help.
