I don't know what I did to my display manager in the past (I had xubuntu at some point, but I got rid of it, and don't see any remnants of it...), but I just upgraded to Ubuntu 11.04 and expected to be greeted with a fancy new Unity interface... but all I got was the same old thing I had before.

What would be preventing Unity from running?

I'm running Ubuntu in a VM, and have activated accelerated 3d graphics, so Ubuntu is not asking me to switch to classic desktop mode (and I have not selected it).

I think in 11.10, you've seen the Unity 2D. Maybe your pc isn't very fast? In 11.04 the classic desktop showed up, and in 11.10 Unity 2D.

Hmm, I guess I don't know how to check whether I'm using Unity 2D or 3D. I had enabled 3d hardware acceleration in VMWare when I was on 11.04, but it still didn't do the trick. – mltsy Dec 12 '11 at 18:22

Upgrading to 11.10 gave me the new sidebar and other features I was looking for. I don't know what happened. Or maybe those didn't exist 11.04? I thought they did.

Did you check at login to have the Unity selected? It sounds you are logged in the Gnome shell. At login page, there is a switch-er from Unity to Gnome.

Yeah, I did see that - was selecting the right one, but still no new interface. Upgrading to 11.10 solved the problem though. – mltsy Dec 12 '11 at 17:54
