You need to remove the fglrx drivers, at the moment (fglrx 11.9) do not work with GNOME Shell.

You need to access a terminal (press Ctrl+Alt+F1) or boot in to recovery mode (press Shift key right before Ubuntu is supposed to load and keep it pressed until the Grub menu comes up).

Login and run:

sudo sh /usr/share/ati/fglrx-uninstall.sh
