Bug Description
Hello.
===== Expected Behavior =====
The funktion-keys on "F1" and "F2" should change brightness of the screen.
===== Instead =====
* The Screenbrightness is not affected.
* From time to time after waking up from standby the brightness is changed. The only rebooting helps. I am not sure how to reproduce this, sorry.
===== System =====
$ lsb_release -rd
Description: Ubuntu 12.04 LTS
Release: 12.04
Further infromation I will gladly include. Just ask.
