GDM refuses to start when using the gnome3-team/gnome3 ppa

[Fran Dieguez]

Hi all,

I have tried Ubuntu-GNOME 13.04 with the gnome3-team/gnome3 PPA and I 
can't login in my user session because GDM refuses to start. If I add 
the gnome3-staging ppa, GDM works like a charm.

Apparently, the screens hangs with plymouth in the screen (with the blue 
curtains) and the GDM password prompt is not shown.

Thanks for the hard work!

Regards
