I accidentally made GNOME-Shell unusable by testing a theme which completely broke the environment. After I've logged in nothing happens, all I get is an empty desktop.
I can't change the GNOME-Shell theme through gnome-tweak-tool when I'm not currently running the GNOME-Shell so how can I change this manually? There must be a value in gconf or something that I can edit to restore the shell, right?
Please help me out here? :)
First you need to get hold of a theme, if you don't got one you can find one here. After you downloaded the theme, unzip it to "/usr/share/gnome-shell/theme". Then you can reload gnome-shell by ALT+F2 and typing gnome-shell --replace Or just log out and back in again.
Hope it helped.
Or you can use this command:
