Most of you probably have heard that Fedora 13 will feature experimental 3D support for the Nouveau open source driver for Nvidia cards. This support, however, is not enabled by default. To enable it you need to install the mesa-dri-drivers-experimental package. I, personally, do it like this(if you haven’t configured sudo, you’ll have to perform this as root):
sudo yum install mesa-dri-drivers-experimental
Afterwards you can enable Compuz, play chromium-bsu or whatever your heart desires.
