This tutorial shows how you can enable Compiz Fusion on
a Fedora 15 GNOME desktop (the system must have a 3D-capable
graphics card - I'm using an NVIDIA GeForce 8100 here).
With Compiz Fusion you can use beautiful 3D effects like wobbly
windows or a desktop cube on your desktop. I will use the free
nouveau driver in this tutorial instead of the proprietary NVIDIA
driver. nouveau is an accelerated Open Source driver for NVIDIA
cards that comes with experimental 3D support on Fedora 15 - on my
test system 3D support was working without any problems.
