I have ubuntu 12.04 and I am trying to install a gtk3 theme but when I try to add the shell extensions for the gnome tweak tool (advance settings) it goes fine on the terminal and seams to install fine but when I click on shell extensions nothing appears therefore I cant activate any themes I have downloaded.
I am a newbie on any lunix os but I want to make this works, so please if anyone know how I can make this work let me know.
thanks
