Before using the driver, you need to lower your system protection so SElinux doesn't prevent the driver to load.
no -- with the fedora rpm you NEVER need to touch the se context
for the nvidia driver
way,way,way back many many years ago a setbool was needed in fedora 5 and 6 IF AND ONLY IF
the nvidia.run was used ( bUT NEVER FOR A RPM !!! )
Are you using a very old nvidia card that needa a 96 or 173 driver ??
if so BUY a new card
at this time there is NO support for the 96&173 driver from nvidia
and as such fedora 13 will not run with the current xorg 1.8
