Comment 8 for bug 1069272

Hello, my workaround was installing "gnome-shell" and then you can write in your ~/.xsession file the gnome session you want from all located in /usr/share/xsessions/ (gnome-classic, gnome-fallback, etc.) and it works. The problem is that the "sessions" button has no elements, so you might create a script to log out from the session.
