Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start with X enabled
Actual results:
A black screen. I can reboot my machine by pressing 'CTRL+ALT+F2', logging in as root and run 'shutdown -r now'. But while doing this there is still a black screen.

Expected results:
X should start.

Additional info:
Plymouth works fine. Booting into init 3 also works fine. Booting with 'nomodset' makes X working.
