Matt has a post over on his blog about how to get the NVIDIA driver working under Fedora 12. I currently use the Nouveau driver, but I’m sure it’ll come in handy in the future. Thanks Matt!
It wasn’t as straight forward as it _should_ have been, as apparently there is a bug in the current (at time of writing) version of Xorg, which causes X to run really slow.
I’m not convinced that it’s a bug in X.org, sounds like a problem caused by the NVIDIA driver. If only it were open source..
