Description Garry Williams 2014-05-03 20:15:41 UTC 
This is a regression.

Brightness control stopped working on Dell XPS-13 after installing
3.14.2-200.fc20.x86_64.  Previous kernel was 3.13.10-200.fc20.x86_64.
OSD shows changes when Fn-F[45] are pressed or when idle kicks in
dimming, but actual screen brightness remains unchanged.
