I had gdm issues on my f19 to f22beta upgrade too. Startx worked. Worse, the lock screen cannot unlock. Claims wrong passwd. Killing Xorg just led to restarted locked screen. Only way out was init 1

Thanks for the report, but I'd like to keep things precise and clear so we don't confuse ourselves: is this a system with dual GPUs? When you say 'GDM issues', do you have the same symptom as Chris (boot to a black screen)? If you edit /etc/gdm/custom.conf and uncomment the line:

#WaylandEnable=false

and reboot, does it start working? Thanks! (same questions for all testers...)
