I'm having a bit of trouble getting gnome-shell to work ever since I installed an extension (I don't know which) on 11.10. So what I would like to know is: How can I completely uninstall EVERYTHING gnome-shell related (all the extensions, gnome-tweak-tool, etc.), everything - so I can start fresh and re-install 'em all one by one?
Thanks in advance.
EDIT: After a long and hard search (for me anyway) I found it:
sudo apt-get remove gnome-shell-extensions-*
