Ubuntu – GNOME Shell User Theme Extension

Geeky Way

You can install user-themes and other extensions from PPA, since extensions are not available in official repositories. Enter following commands to have themes working.

sudo add-apt-repository ppa:webupd8team/gnome3

sudo apt-get update

sudo apt-get install gnome-shell-extensions-user-theme

Now restart gnome-shell using Alt+F2 run dialog and entering r.

Enable extension form gnome-tweak-tool and you're done.

Preferred Alternate Way

This is by far the easiest way to install "user-themes" extension, as well as many other GNOME shell extensions.

• Just open Firefox (you CAN NOT use any other browser, as of now).
• And visit extensions.gnome.org
• You can search for extension you're looking for, as well explore other great extensions.

• Found the extension? Just click on the switch to install it.

• Aah..... by the way for user-themes, you can get it here.

Note: GNOME Shell doesn't have Alt+F2 Run dialog enabled by default, so if that's the case, you can enable it via Keyboard Settings>Shortcuts>System.

Just to make sure - Did the instructions you followed involve extracting the theme to /usr/share/themes? If not you can find a more detailed description of how to install a theme in 11.10 here.
