# Install NVIDIA Drivers on Red Hat Enterprise Linux 9.x

## Introduction

In this article, I'll tell you how to install the NVIDIA GPU drivers on Red Hat Enterprise Linux (RHEL) 9.x

## Check system has an NVIDIA GPU installed

You can check whether your system has an NVIDIA GPU installed with the following command

```bash
lspci | egrep 'VGA|3D'
```

You can see NVIDIA Tesla T4 GPU installed in the system.

## **Install the EPEL Repository**

We will have to install the required build tools and the required dependency libraries for compiling the NVIDIA kernel modules. Some of these are available in the RHEL 9 EPEL repository.

First, update the DNF package repository cache with the following command

```bash
sudo dnf makecache
```

Enable the official RHEL 9 CodeReady Builder package repository and install it.

Following are the commands to enable and install respectively

```bash
sudo subscription-manager repos --enable codeready-builder-for-rhel-9-$(uname -i)-rpms
```

```bash
sudo dnf install https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
```

To confirm the installation, press **Y** and then press **<Enter>**

The **epel-release** package should be installed, and the EPEL repository should be enabled.

For the changes to take effect, update the DNF package repository cache with the following command

```bash
sudo dnf makecache
```

## **Install the Required Dependencies and Build Tools for Compiling NVIDIA Kernel Modules**

To install the required build tools and dependency libraries for compiling the NVIDIA kernel modules on RHEL 9, run the following command

```bash
sudo dnf install kernel-devel-$(uname -r) kernel-headers-$(uname -r) gcc make dkms acpid libglvnd-glx libglvnd-opengl libglvnd-devel pkgconfig
```

The required packages are being downloaded from the internet. It will take a while to complete.

Once the packages are downloaded, you will be asked to confirm the GPG key of the EPEL repository.

To confirm the GPG key, press **Y** and then press **<Enter>**.

The required dependency libraries and build tools for compiling the NVIDIA kernel module should be installed at this point.

## **Add the Official NVIDIA CUDA Package Repository**

To add the official NVIDIA CUDA package repository on RHEL 9, run the following command

```bash
sudo dnf config-manager --add-repo http://developer.download.nvidia.com/compute/cuda/repos/rhel9/$(uname -i)/cuda-rhel9.repo
```

For the changes to take effect, update the DNF package repository cache with the following command

```bash
sudo dnf makecache
```

## **Install the Latest NVIDIA GPU Drivers**

To install the latest version of the NVIDIA GPU drivers on RHEL 9, run the following command

```bash
sudo dnf module install nvidia-driver:latest-dkms
```

To confirm the installation, press **Y** and then press **<Enter>**.

NVIDIA GPU drivers packages and the required dependency packages are being downloaded from the internet. It will take a while to complete.

Once the packages are downloaded, you will be asked to confirm the GPG key of the official NVIDIA package repository. Press **Y** and then press **<Enter>** to confirm the GPG key.

For the changes to take effect, restart the system with the following command

```bash
sudo reboot
```

## **Verify NVIDIA Drivers are Installed Properly**

Once the system boots, you should see that the proprietary NVIDIA GPU drivers are used with the following command

```bash
lsmod | grep nvidia
```
