Comment 97 for bug 954661

Hi,

Im on Linux Linux Bob-Dell 3.2.0-53-generic #81-Ubuntu SMP Thu Aug 22 21:01:03 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
and the brightness control is not working. The notification panel is shown when using F4/F5 but the brightness level does not change.
It was working yesterday but after a software update today it broke again :/
Please Help!!
