from a couple of days I'm having a problem with Gnome3 gnome-shell. When I reboot / power-on the machine, after the GDM login the DE is stuck without opening gnome-shell. If I restart gdm from another tty, then everything works (GDM restarts and gnome-shell appears). So it hangs only the first time i login.
I was looking for more information on what is happening, but I can't find a gdm or gnome-shell detailed log. any suggestions?
Currently using Gnome3 PPA + (ricotz PPA) + ATI open source drivers
