I installed ubuntu 12 (unity), I want to have gnome 3 like the videos in this link >>http://www.filiwiese.com/installing-...cise-pangolin/
but I made some installations which let me have gnome in the login menu but not like this vedio at all it was even without a bar with clock on it !!! and even no menu for shutdown or logout !!!!
so please help me to have what in this link video ( i think it's gnome 3 shell/desktop) and also keep my unity working fine too
thank you so much,
