Comment 34 for bug 1302416

I do have the same problem. The problem was i connected to a second monitor and revert my graphic settings to Nouveau. I previously used nvidia graphic driver but the dual monitor doesn't work. I'm not sure whether the dual monitor is causing the problem or the Nouveau graphic Driver. I run ubuntu 14.04. I'm open to help if you guys need any information regarding my system or do some test.
