Hello everyone!

I searched for this on the net, but didn't find any solution that works for me.

I'm trying to use gnome-shell on Precise Pangolin AMD64, but it doesn't works. After I make login, all I get is an empty screen, with no panels, icons, or anything but the mouse cursor and the wallpaper. Right clics doesn't work, so, the only thing I can do is hit ctrl+alt+del and logoff.

Unity, Gnome Classic, and all the other sessions works with no problems. The compiz runs ok as well (tried even the water effect).

My specs are below:

Proc: AMD Bulldozer FX8120 8-core
RAM: 8GB DDR3 dual-channel
MB: Asus M5A78L LE
Video: Nvidia GeForce GT240, 512MB GDDR5 (Zotac)
Ubuntu Version: Precise Pangolin 12.04 AMD64

Can u guys help me, plz?
