+title: Installing NVIDIA GPU Drivers

+
+## Introduction
+
+Nvidia is one of the most popular GPU manufacturers. There is more than one way to install Nvidia GPU drivers. This guide uses Nvidia's official repository to install their drivers. Therefore much of this guide is referenced from [Nvidia's installation guide](https://docs.nvidia.com/cuda/pdf/CUDA_Installation_Guide_Linux.pdf).
+
+!!! Note
+
+    The pre-installation actions link is broken in Nvidia's official guide. You will need to install necessary utilities and dependencies to install the Nvidia driver from their official repository. 
+
+Some other alternative ways to install Nvidia drivers include:
+
+- Nvidia's `.run` installer
+- Third-party RPMFusion repository
+- Third-party ELRepo driver
+
+In most cases, it's best to install Nvidia drivers from the official source. RPMFusion and ELRepo are available for those who prefer a community-based repository. RPMFusion is considered to work best for older hardware. It is advisable to avoid using the `.run` installer. While convienent, using the `.run` installer is notorious for overwriting system files as well as incompatibility issues. 
+
+## Assumptions
+
+For this guide, you need the following:
+
+* Rocky Linux Workstation
+* `sudo` privileges
+
+## Install necessary utilities and dependencies
+
+Enable the Extra Packages for Enterprise Linux (EPEL) repository:
+
+```bash
+sudo dnf install epel-release -y
+```
+
+Installing development tools ensures necessary build dependencies are met. 
+
+Install the `Development Tools`:
+
+```bash
+sudo dnf groupinstall "Development Tools" -y
+```
+
+The `kernel-devel` package provides necessary headers and tools to build kernel modules. 
+
+Install it with the command below:
+
+```bash
+sudo dnf install kernel-devel -y
+```
+
+Dynamic Kernel Module Support (DKMS) is a program used to automatically rebuild kernel modules. 
+
+Install the `dkms` package: 
+
+```bash
+sudo dnf install dkms -y
+```
+
+## Install NVIDIA Drivers
+
+After installing the necessary prerequisites, it is time to install the Nvidia drivers.
+
+Add the official Nvidia repository with the following command:
+
+!!! Note
+
+    If you are using Rocky 8, replace `rhel9` in the file path with `rhel8`.
+
+```bash
+sudo dnf config-manager --add-repo http://developer.download.nvidia/compute/cuda/repos/rhel9/$(uname -i)/cuda-rhel9.repo
+```
+
+Next, install a set of packages necessary for building and installing kernel modules:
+
+```bash
+sudo dnf install kernel-headers-$(uname -r) kernel-devel-$(uname -r) tar bzip2 make automake gcc gcc-c++ pciutils elfutils-libelf-devel libglvnd-opengl libglvnd-glx libglv-devel acpid pkgconfig dkms -y
+```
+
+Install the latest NVIDIA driver module for your system:
+
+```bash
+sudo dnf module install nvidia-driver:latest-dkms -y
+```
+
+## Disable nouveau
+
+Nouveau is an open-source NVIDIA driver that provides limited functionality compared to NVIDIA's proprietary drivers. Its best to disable it when using to avoid driver conflicts:
+
+Open the grub configuration file with an editor of your choice:
+
+```bash
+sudo vim /etc/default/grub
+```
+
+Add `nouveau.modset=0` and `rd.driver.blacklist=nouveau` at the end of `GRUB_CMDLINE_LINUX`. 
+
+The value of `GRUB_CMDLINE_LINUX` should look similar to the text below although it will not, nor does it need to be, an exact match:
+
+```bash
+GRUB_CMDLINE_LINUX="resume=/dev/mapper/rl-swap rd.lvm.lv=rl/root rd.lvm.lv=rl/swap crashkernel=auto rhgb quiet nouveau.modeset=0 rd.driver.blacklist=nouveau"
+```
+
+Reload the grub environment:
+
+```bash
+grub2-mkconfig -o /boot/grub2/grubenv
+```
+
+Reboot:
+
+```bash
+sudo reboot now
+```
+
+## Conclusion
+
+Congratulations! You've successfully installed NVIDIA GPU drivers on your system using NVIDIA's official repository. Enjoy the enhanced capabilities of your NVIDIA GPU that the default Nouveau drivers can't provide.
