“This tutorial shows how you can enable Compiz Fusion on an
Ubuntu 11.04 (Natty Narwhal) desktop with the classic GNOME
interface, i.e., no Unity (the system must have a 3D-capable
graphics card – I’m using an NVIDIA GeForce 8200 here). With Compiz
Fusion you can use beautiful 3D effects like wobbly windows or a
desktop cube on your desktop.“This document comes without warranty of any kind! I do not
