GNOME 3 problem

[Nism0.sdt]

Hi.

I decided to play a bit with new GNOME 3, so I upgraded my old Ubuntu 11.04 to 12.04 LTS . Than I've installed gnome-shell (3.4 version), but, when I reboot my computer and choose GNOME session, my "GNOME 3" doesn't looks like it should (like this I guess :
http://www.gnome.org/gnome-3/ ) but looks like this :

What I should to do, to get proper effect , I mean the real GNOME 3 environment .

If you are selecting Gnome during login it should look as the first picture. If it is defaulting to Classic Gnome (Second Picture) the computer may have a problem running the Gnome Shell. If you can run Unity 3D you should have no problem running the shell. Can you tell us about your hardware and computer.
