[mdlug] Mybuntu 11.04 -> Mythbuntu 11.11 causes X server to break

[Tony Bemus]

Im not sure about Mythbuntu but Ubuntu changed from GDM to LDM (Light
Display Manager) for the login manager.  I had a similar problem when I
did my upgrade and I removed my xorg.conf file and rebooted.  After that
everything worked.
