Centos 7

Installing NVIDIA drivers

First run this to get video card version:

[root@vov ~]# lspci | grep -i vga | grep -i nvidia
01:00.0 VGA compatible controller: NVIDIA Corporation GK107 [GeForce GT 640] (rev a1)

After you know what card you have go to this site and download the driver for your version of linux. Make sure you choose 64bit linux as os.

http://www.nvidia.com/Download/index.aspx?lang=en-us

When the file is done downloading, move it to the /root folder and fix perms.

For me that command looked like:(you will need to fix the paths in your)

mv /home/mike/Downloads/NVIDIA-Linux-x86_64-367.44.run /root
chown root.root /root/NVIDIA-Linux-x86_64-367.44.run
chmod +x /root/NVIDIA-Linux-x86_64-367.44.run

Now after this you gotta do some stuff in yum.

yum install epel-release -y
yum install dkms glibc-devel.i686 libstdc++-devel.i686
yum update

Once that has been done, now we need to alter the kernel options.

vim /etc/default/grub

Find this line:

GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos_vov/root rd.lvm.lv=centos_vov/swap rhgb quiet"

And change it as follows:

GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=centos_vov/root rd.lvm.lv=centos_vov/swap rhgb quiet nomodeset rdblacklist=nouveau"

Once that edit is made you need to rebuild grub2.

cp /boot/grub2/grub.cfg /root/grub.cfg
grub2-mkconfig -o /boot/grub2/grub.cfg

Now you need to reboot the system, to finish disabling nouveau.

reboot

Once the server has rebooted, open a terminal and su to root.

su -

Now you need to switch to runlevel 3 so the gui is disabled.

init 3

Login as root and run the following:

/root/NVIDIA-Linux-x86_64-367.44.run

Follow the prompts through it, I recommend that you build the dkms module, and build the 32 bit comparabilities library. When it asks to replace the x-config select yes. Now when your back at the CLI.

Type reboot to finish the process off.

reboot
