I think that may be related to the problem i'm having. How would I uninstall the 4191 drivers for 2.4-18.8.0 so I can re-make then for 18-19.8 ??? Won't let me build them from Tar.gz right now.......?
rpm -e NVIDIA_GLX
rpm -e NVIDIA_kernel
That should remove the two packages, so you can start fresh.
run rpm -qa | grep NVIDIA
to see all installed packages with the string "NVIDIA" in it's name.
