I have just done some major system upgrade (I was pretty busy and haven't updated this machine for a while... probably ~1.5 month). And after reboot gdm refused to work properly. Looks like it's starting (I see blue stripes) but don't see login window, buttons, or anything else (only cursor). Fortunately I managed to run gnome manually (exec ck-launch-session ...).
Until now I was only using gnome in fallback mode and gdm simple greeter. If it matters I didn't even have gnome-shell installed on my system. Also just before system upgrade I was messing for a while around gnome themes, appearance, etc. I haven't touched gdm but I might have accidentally changed something in gconf-editor.
Unfortunately logs aren't much help for me this time.

Thanks in advance for any help!
