I haven't had any problems with it though. Tribe 2 installed in about 15 minutes. Compiz Fusion was enabled. I built my system to be Linux compatible, so it's not too surprising. I don't even have to install any drivers since I have an Intel GPU. The Restricted Drivers Manager should work for people with ATI or Nvidia GPUs though.
The desktop effects are a little different from Feisty. The windows kind of zoom in and out when you open and close them and the windows don't wobble. I haven't tried to install any other Compiz plugins.
