Hi,
You could have installed the Nvidia proprietary driver first and then blacklist nouveau.
Anyway, try pressing "e" instead of ENTER when choosing what to boot with GRUB. You will be given a command which boots the kernel. Add "nomodeset" at the end of the "linux ..." line. Also, remove "blacklist" in the booting parameters, if any. Normally at this point you should be able to boot to a CLI with a login on a black background.
If the above does not work, boot the computer with a USB or CD/DVD, mount your filesystem and remove the blacklisting, both in etc and grub.cfg. Then, install the proprietary nvidia driver and then only, blacklist nouveau by the just adding the line in /etc/modprobe.d/blacklist.conf
All the best.

i have found that after blacklisting nouveau you NEED!!!!! to rebuild the boot image
THEN you can install the driver
mind you i use the .run and not the prebuilt for cent/sl or fedora or suse
and i use SL 6
however the kmod-nvidia.rpm should auto do that

Hi aragorn2101,
Thanks you for tour reply and suggestion.
nomodeset does help me to install nvidia driver but some how after install. boot up screen hangs for couple of minutes before booting into OS.
i also have found alternative solution by using a low end graphic card to Geforce 210 to display and install driver for my GTX 950.

I think you are mistaken (but I'm learning all this also. Is it the free 30day RHEL trial?)
web-search: rhel rebuild boot image
The results mention `mkinitrd`; (study the concept of initrd: I think it's needed for RHCE)
`man grub2-mkconfig` indicates that only updates grub.cfg (text file)
OR does the `sh NVIDIA……run` (in your prior Thread) build a new kernel+initrd? Sorry, I don't know. (`ls -l /boot` to see them)
Best wishes! (Wow, you are learning all this 100x faster than me, a very OLD former Unix-SA!)
p.s. Goo... isn't giving me 'good' results, from my web-search for:
What is the linux|kernel|vmlinu{x,z}|bzImage|initrd intitle:"boot image"?
? ...|vmlinux|vmlinuz|... -android -arm -pxe -site:quora.com

Hi Jjanel,
Centos is a free OS. you can download and try it out.
grub2-mkconfig -o /boot/grub2/grub.cfg is issue as there are changes in grub file as i blacklist nouveau. Does it really matter to boot image ( i'm not sure about it, still new in Linux Family)
Sh NVIDIA....run will build a new kernel for it ( if im not mistaken), in order to use its drivers.
