I've got a fairly new desktop system. Installed Fedora 11 and kmod-nvidia. Everything was working, but suddenly my programs are complaining that my hardware does not support 3D acceleration. I've removed and reinstalled the kmod-nvidia packages but still have the same result. I can't enable Compiz either. Really don't know how to troubleshoot this. I've come across everything from bugs to repo updates that are not in full sync with my kernel yet. Any ideas?
