“This tutorial shows how you can enable Compiz on a Linux Mint
12 Lisa desktop (the system must have a 3D-capable graphics card –
I’m using an NVIDIA GeForce 8200 here). With Compiz you can use
beautiful 3D effects like wobbly windows or a desktop cube on your
desktop.“I have tried this on a desktop computer with an NVIDIA GeForce
8200. It should work the same way with all other NVIDIA graphics
cards. Compiz is not supported on GNOME 3 yet, that’s why this
how-to is applicable only for the classic GNOME desktop. To switch
to the classic desktop, log out of your current session and click
on the cogwheel icon next to your username in the log-in
screen:”
