>> Enabling Compiz Fusion On An Ubuntu 8.10 Desktop (NVIDIA GeForce FX 5200)
This tutorial shows how you can enable Compiz Fusion on an Ubuntu 8.10 (Intrepid Ibex) desktop (the system must have a 3D-capable graphics card - I am using an NVIDIA GeForce FX 5200 here). With Compiz Fusion you can use beautiful 3D effects like wobbly windows or a desktop cube on your desktop.
