11.10gnomegnome-shellgnome-shell-extension
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-*
The error message you are reporting with gnome-tweak-tool occurs when either logging into Gnome-Classic or if logging into Gnome-Shell - but it doesnt allow a full Gnome-Shell GUI but reverts to Gnome-fallback.
From your latest edit - this is the case - the screenshot shows that you are using gnome-fallback. This occurs when 3D acceleration fails.
N.B. Gnome-Shell should look like:
To get the full Gnome-Shell GUI, check that your virtualbox settings have 3D acceleration checked, 128MB VGA RAM and that your host graphics supports 3D Hardware acceleration.
You are almost there. After:
~/.local/share/gnome-shell/extensions/ and the extension should appear in the gnome-tweaks tool (restart that one as well).
