After installed gnome-shell session on Ubuntu 12.04, you may be interested to try out a few themes on your desktop, and this simple tutorial will show you how to do it.
Preparation:
Apart from ensuring you actually have gnome-shell installed, the first thing need to do is installing gnome-tweak-tool and gnome-shell-extensions-user-theme.

I'm trying to install themes with gnome tweak, and I need to install gnome-shell-extensions-user-theme because otherwise I cannot see the shell extensions tab. However, I cannot install shell extensions.
Half-left has designed yet another great theme for Gnome Shell. His latest theme is based on the look of Ubuntu 12.04 Precise Pangolin and it looks really beautiful.

Instructions
Use User Theme Extension and Gnome Tweak Tool to switch Gnome Shell themes. Gnome Tweak Tool can be installed from Ubuntu Software Center.
I switched from Unity to Gnome 3.4 but I'd like to tweak my desktop a bit. I want to use a gnome shell theme but the gnome tweak tool won't allow me to modify the gnome shell themes. I've read somewhere that if I reinstall the gnome-shell then it would conflict with Unity and I wouldn't be able to safely use Unity anymore. Is there a way to change the theme without reinstalling the gnome-shell?
John Stowers has announced the release of GNOME Tweak Tool 3.6.0, a utility popular among users of the GNOME 3 desktop environment. The GNOME Tweak Tool is better known by the users of Ubuntu as Advanced Settings. As you might expect, it's a very important tool for customizing how your Gnome 3 environment looks and behaves.
When I run gnome-tweak-tool, a lot of the options are locked. In particular, I'm talking about the gnome shell theme, and the gnome shell extensions. They all have a "warning" type icon with an exclamation point next to them.
I am not logged in to a unity session, just regular "gnome".
I'm having a bit of trouble getting the gnome-shell to work ever since I installed an extension (I don't know which) on 11.10.
I'm experiencing some problems with Ubuntu Gnome Remix 12.10 64bits.
My gnome-tweak-tool doesn't apply themes properly. For the gkt themes, I noted that they are not fully applied. For example, I select Elementary's gtk theme and the window's border (metacity?) still with Adwaita. The theme also looks weird, what led me to believe that there was some engine missing, but that wasn't the case.
OK, so I am now on my 6th fresh format and install of Ubuntu 12.04 (in under a month). I installed gnome shell, gnome desktop, and tweak tool. For whatever reason I cannot select _shell user-theme" because there is an orange triangle next to it which when I hover over it I get "shell user-theme extension not enabled". ow do I fix this?
