Well, I got into gnome-shell on F14 and can't figure out how to kill it. I did it from the menu, rather than a terminal, a mistake. How do I get out of this !~!@#$% thing and get my menus back?
Edit: I did this
gconftool-2 --unset /desktop/gnome/session/required_components/windowmanager
and then logged out of gnome.
