if you use the nvidia.run driver you NEED to make sure it is the correct one for your card.
most of the new cards use the 185.18.36 driver the 32 bit or 64 bit depending on the OS.
-- 32 bit --
read the nvidia README file
you will need to install the kernel-devel and kernel-headers
yum install kernel-devel kernel-headers
and have gcc installed
I do this by using "groupinstall"
yum groupinstall "Development Tools" "Development Libraries"[/code]
I copy the .run driver ( NVIDIA-Linux-x86-185.18.36-pkg1.run is the current for new cards )
chmod +x *.run
but you might need to use this command to run it
" sh ./*.run "
then fallow the onscreen instructions
then BEFOR rebooting reinstall the OpenGL mesa
then for EVERY kernel,X11 and xorg update you MUST reinstall the .run driver AND mesa ( yum reinstall mesa* )
yum install mesa-devel
yum reinstall mesa*
