Public bug reported: And this started happening recently. After the initial installation of Ubuntu 12.04 LTS everything was OK. I believe, the problem occured after an upgrade (I upgrade everything all the time.). So, when I try to turn the brightness up (using the Fn + Arrow UP buttons) the dial goes up only a quarter and stops. I still can control it from the "System Settings/Brightness & Lock" window though ... The driver is: IntelĀ® Sandybridge Mobile.
That's it. Thanks. ** Affects: ubuntu Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1030012 Title: Samsung RC512 brightness control goes up only a quarter ...
