Am I using Unity or Unity 2D?

I can't tell the difference between 2D and Unity(3D?) when I log in with the trial LiveCD. How can I tell which one I am using and if I am using compiz ok?

Open a terminal and type


If the output is ubuntu then you're running Unity; ubuntu-2d otherwise.

WoW! I would have never guessed!. It says ubuntu. Ubuntu is for Unity and ubuntu-2d is for...? But it looks exactly the same . I can not tell the difference. Maybe the value of $DESKTOP_SESSION only stores my choice when I logged in. But that I know. What I don't know is what has become effective. If I am running compiz or not. If I am using all the features or I am missing most. – Robert May 3 '12 at 17:01
@Robert: this is rather obvious, but if I understand your question correctly, you can run ps x | grep compiz to see if compis is running. – Dan Dascalescu Dec 30 '12 at 3:37
