Ubuntu – Can’t use GNOME shell on VirtualBox

11.10gnomevirtualbox

I am running version 11.10 on a VirtualBox VM with ~1000MB dedicated memory, on mid-range hardware and using Windows Vista as a host. It came with Unity pre-installed.
I ran:

apt-get install gnome-shell

When it was complete, I logged out from Unity, clicked on the Gear icon to select my UI and noticed that there was no trace of Gnome Shell:

The only available options

I tried selecting GNOME thinking that it could be the right one but I was presented with this desktop, which I don't believe to be the Gnome Shell Desktop:

Am I doing anything wrong?

3D Acceleration is "experimental" in VB and may not be properly supported. Also which version of Virtual Box are you using. The Open Source version doesn't seem to support all the functions of the one downloaded off the site.
I don't like suggesting closed source, but your situation may call for it.

Also I'm going to try running sudo apt-get install gnome-shell on my 11.10 machine and see what it looks like. There's still the possibility that it's not VB.
