1. Acquire the Nvidia driver:
Download the appropriate driver for your graphics controller from http://www.nvidia.com
Ensure that this driver is saved to the local disk of the target system. Installing from an external device, such as a flash drive, has been known to cause issues up to and including installation failure.
2. Edit Grub2 to blacklist the Nouveau driver:
Edit /etc/default/grub and add the following to the GRUB_CMDLINE_LINUX line:
Sometimes even after following the above steps to blacklist nouveau module, it is seen loaded at boot. # lsmod | grep -i nouveau . Most likely, this gets loaded from initramfs. In such cases, follow How to blacklist nouveau module on Red Hat Enterprise Linux 7?
The driver can not be installed if the X server running on system. So make sure the system is started in text mode(runlevel 3).

해결
Note: Before replacing nVIDIA proprietary driver with nouveau driver ensure that hardware is certified to run RHEL-6.X. The xorg-x11-drv-nouveau package shipped with RHEL-6.X doesn't support some nVIDIA Graphics chip that are too old. Use hardware certification link to check all certified hardware's.
Step 2: Installation of NVIDIA proprietary driver blacklists nouveau driver hence during post un-installation of NVIDIA driver go through the following check list.
a1) (RHEL 6 and prior)Remove kernel parameters "rdblacklist=nouveau nomodset=0" from /boot/grub/grub.conf file - Basically remove any commands that blacklist or disable nouveau and set modeset to "0" or "off" a2)(RHEL7) Remove the kernel parameters "rd.blacklist.nouveau" "nouveau.modeset=0" and similar arguments from the GRUB_CMDLINE_LINUX line in /etc/default/grub - Rebuild your grub.cfg file with the command: grub2-mkconfig -o /boot/grub2/grub.cfg on legacy installations, or grub2-mkconfig -o /boot/efi/EFI/redhat/grub.cfg for EFI installations
b) Remove or comment the line "blacklist nouveau" from /etc/modprobe.d/blacklist.conf file.
b) If nouveau module is not present in the result of lsmod command output then load it manually. - You may also have to reinstall the 'xort-x11-drv-nouveau' package. Please ensure that you are installing the version of this package that corresponds to the version of your xorg server and kernel version.
