Hi,

I'm experiencing this bug on 

00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core
Processor Family Integrated Graphics Controller (rev 09)

on a Dell Optiplex 990 with a Dell 30" monitor attached. This is a desktop
computer, not a laptop.

I get the following WARNING on 3.13.10-200.fc20.x86_64

I see this bug has a NEEDINFO status. What more information/feedback is needed?
