I downloaded Compiz through the software center after I installed the Gnome because I wanted all those nifty visualizations. When I went to enable the cube and rotate cube, all it was able to do was rotate a panel that would switch me between desktop 1 and 2. There was no way to get to 3 and 4 through that.
Note that I'm a newb at this. I just did a dual install last night.
(If a moderator happens to pass by, let me tell you that I can't edit my profile details. I can't change how I'm using Ubuntu, nor can I change which version I'm using.)
Details: Dual install with Windows. Ubuntu 12.04 on an HP mini-110. Need any more details?
