(changes you to cli mode - no gui)
su - (supply root password)
nvidia-installer --update -f
and see if the drivers reinstall
when yer done,
(to cancel the su mode)
( to go back to gui mode)
other than that, i'm stumped...
and, for the record, I'm not convinced it's the drivers...
and, for giggles, do this:
rpm -qa |grep nvidia
to see if you installed the rpm versions...
if they are installed, you can
rpm -e RPMPACKAGENAME
where RPMPACKAGENAME are the nvidia rpms listed with the -qa line...
just be careful, and make sure to read the man pages and be sure of what you want to accomplish... we don't wanna muck up your system for you...
