Description of problem: GDM reports "oops, logout" unable to login


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


How reproducible:
Configure multi-card, multi-head setup

Steps to Reproduce:
1. boot system using xorg.conf to load intel (i915) and nvidia (GeForce 9500 GT (G96))
2.
3.

Actual results: /var/log/Xorg.0.log reports nor /var/log/gdm/:0.log report severe (EE) errors.  Both gpus, intel and nvidia drivers are successfully loaded.  

Expected results: gdm works the same as f19
