The NVIDIA linux driver cannot be installed when the system is using the nouveau driver. The nouveau driver has been installed on all of the systems I’ve set up so far. To use the nvidia driver, do the following:
1. Edit /etc/grub.conf and add rdblacklist=nouveau vga=791 to the end of the kernel line.
2. yum remove xorg-x11-drv-nouveau
3. Edit /etc/inittab to change the runlevel to boot to from 5 to 3.
4. Create the file /etc/modprobe.d/blacklist-nouveau.conf and in it, put the following line:
blacklist nouveau
5. Reboot
6. Install the Nvidia driver and make sure to run the nvidia config in the last step.
7. Test it out by either rebooting or running init 5.
