That's not a gnome-session bug if you're getting as far as usplash.
Could you please boot without "quiet" and "splash" and observe the last
messages that appear on the console when you shutdown from your
graphical session.
** Package changed: gnome-session (Ubuntu) => ubuntu
** Changed in: ubuntu
Can any of the reporters of this but run the following command and post the
output to this bug
aptitude search restricted
I want to see what restricted modules you have installed
thanks
