After a fresh install of OpenSUSE Tumbleweed from the DVD (I've tested snapshot
20160831 and 20160913) with gnome as the default desktop environment, if you
try to login the screen will flicker black and you will be kicked back to GDM.

Reproducible: Always

Steps to Reproduce:
1. Install OpenSUSE Tumbleweed Snapshot 20160831 or 20160913 with gnome as the
default DE.
2. Boot up and attempt to login. The screen will flicker, and you will be
returned to GDM.
Actual Results:  
After pressing the 'login' button, the screen will flicker black, and then you
will be returned to GDM.

Expected Results:  
GDM should log you in to your desktop environment or window manager.
