Most users of NVIDIA graphics cards prefer to use the drivers provided by NVIDIA. These more fully support the capabilities of the card when compared to the nouveau driver that is included with the distribution. These are the steps to install the NVIDIA driver and disable the nouveau driver.
Prepare your machin
$ yum -y update $ yum -y groupinstall "GNOME Desktop" "Development Tools" $ yum -y install kernel-devel
Download the latest NVIDIA driver for unix.
==> http://www.nvidia.com/object/unix.html ==> Latest Long Lived Branch version
Note: If using a recently released, top end GTX or Tesla you may get more support with the Latest Short Lived Branch instead.
In order to have the NVIDIA drivers rebuilt automatically with future kernel updates you can also install the EPEL repository and the DKMS package. This is optional.
$ yum -y install epel-release $ yum -y install dkms
Reboot your machine to make sure you are running the newest kernel
/etc/default/grub. Append the following to "
Generate a new grub configuration to include the above changes.
$ grub2-mkconfig -o /boot/grub2/grub.cfg
/etc/modprobe.d/blacklist.conf and append:
Backup your old initramfs and then build a new one:
$ mv /boot/initramfs-$(uname -r).img /boot/initramfs-$(uname -r)-nouveau.img $ dracut /boot/initramfs-$(uname -r).img $(uname -r)
Reboot your machine
If your machine doesn't boot to a login prompt disconnect your monitor from the graphics card and plug directly into the onboard VGA port. Alternatively SSH directly into the machine.
The NVIDIA installer will not run while X is running so switch to text mode:
$ systemctl isolate multi-user.target
Run the NVIDIA driver installer and enter yes to all options.
$ sh NVIDIA-Linux-x86_64-*.run
Reboot your machine
Optionally install NVIDIA's CUDA Toolkit
Download the latest CUDA Toolkit (runfile installer option, not the rpm download)
==> https://developer.nvidia.com/cuda-downloads ==> Linux ==> x86_64 ==> RHEL/CentOS ==> 7 ==> runfile (local)
Run the CUDA installer.
$ sh cuda_*.run
Say no to installing the NVIDIA driver. The standalone driver you already installed is typically newer than what is packaged with CUDA. Use the default option for all other choices.
To add CUDA to your environment add the following files.
PATH=$PATH:/usr/local/cuda/bin export PATH
set path = ( $path /usr/local/cuda/bin )
