Description of problem:
After logging in to gnome if i try to logout, the screen goes black and I'm not able to do anything from there. I can't go to text mode either and so forced to do a cold reset
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Login to a gnome session
2. Logout from that user/session
3. The screen goes black and the PC becomes unresponsive.
Logout properly and be able to login again.
Assuming that this is with mutter-3.17.92, which has already been reported as bug 1264904. (TL;DR: updating to mutter-3.18.0 should fix this)
