Debian Install Nvidia Driver with Code Examples

Nvidia is one of the most popular graphics card manufacturer around the globe. It provides rigorous support for users to have a better gaming and computing experience. Installing Nvidia drivers improves the performance of the GPU installed on the computer and provides support for many complex programs and games. Debian is an open-source Linux distribution and is considered one of the best OS distribution among users in terms of stability and security. In this article, we will guide you through the process of installing Nvidia drivers on Debian systems.

Step 1: Verify GPU Model and OS Distro

Before we proceed, we need to check the Nvidia GPU model and OS distribution for compatibility. To check compatibility, open Terminal and run the following command:

$ lspci | grep -E "VGA|3D"

This command will list all the graphics card installed in the system, and we will look for the Nvidia GPU. It's highly recommended to use the latest Nvidia driver version downloaded from Nvidia official website.

Step 2: Add Non-free Repository

The Debian OS distribution has a free distribution policy, which means it doesn't bundle with proprietary drivers or software. We need to add the non-free repository to access the Nvidia driver package. To add non-free repository, run the following command:

$ sudo nano /etc/apt/sources.list

Add the following line at the end of the file:

deb buster main non-free contrib

After adding the repository, we need to update the package list:

$ sudo apt-get update

Step 3: Install Required Dependencies

Before we install the Nvidia drivers on the Debian system, we have to install some dependencies that are necessary for the operation of the NVIDIA package. To install dependencies, run the following command:

$ sudo apt-get install build-essential dkms linux-headers-$(uname -r)

The above command downloads all the necessary packages required for installing the Nvidia driver.

Step 4: Install Nvidia Driver

To install the Nvidia drivers run the following command:

$ sudo apt-get install nvidia-driver

This command installs the latest Nvidia graphics driver package from the Debian repositories. The installation process will take some time.

Step 5: Verify the Installation

After the installation, we can verify if the Nvidia drivers have been correctly installed using the following command:

$ nvidia-smi

If everything installed correctly, the above command should output information about the Nvidia GPU, including driver version, CUDA version, GPU utilization, and more.

Step 6: Troubleshooting

If you have installed Nvidia drivers yet facing some issues with graphics, you may want to try troubleshooting some common problems. If you're experiencing any glitches or errors after the driver installation, the first step is to isolate the problem by checking the X11 logs.

To check X11 logs, run:

$ cat /var/log/Xorg.0.log

This command will display the X server logs, where you can identify errors related to display drivers and take corrective measures accordingly.


In this article, we have walked you through the installation of Nvidia drivers on Debian systems. We went through the steps of verifying the compatibility, adding non-free repository, installing required dependencies, installing Nvidia drivers, and verifying installation. Furthermore, we covered common troubleshooting steps if you face any issues with graphics. Installing the latest Nvidia drivers will ensure better GPU performance and better support for complex applications.

Sure! Here are some additional details on the topics covered in the previous article:

Verifying GPU Model and OS Distro

The command "lspci | grep -E "VGA|3D"" is used to detect the graphics card installed on your Debian system. It is important to verify the GPU model and OS distro before proceeding to install the Nvidia driver package. This helps to ensure proper compatibility and prevent any potential issues or errors during installation.

Adding Non-free Repository

The "non-free" repository is not included in the default Debian distribution. This repository contains proprietary drivers and software, including the Nvidia driver package. Adding non-free repository provides access to the Nvidia driver package for installation.

Installing Required Dependencies

There are several dependencies that are required for the proper functioning of the Nvidia driver package. The "build-essential" package contains essential tools necessary for building binary Debian packages. The "dkms" package provides support for Dynamic Kernel Module Support, which enables Nvidia driver packages to be built and installed on your system. The "linux-headers-$(uname -r)" package installs kernel headers that are required for building kernel modules and other system software.

Installing Nvidia Driver

The "nvidia-driver" package is used to install the latest Nvidia graphics driver on your Debian system. It is important to ensure that you have added the non-free repository and installed the required dependencies before proceeding with the installation.

Verifying the Installation

After installing the Nvidia driver package, it is important to verify that the installation was successful. The "nvidia-smi" command is used to check the Nvidia GPU information, including the driver version, CUDA version, GPU utilization, and other relevant details.


If you experience any issues or errors after installing the Nvidia drivers, it is important to troubleshoot the problem. Checking the X server logs can help identify any issues related to the display drivers. Additionally, there are several online forums and resources available for troubleshooting Nvidia driver problems. Updating drivers or rolling back to a previous version can sometimes resolve some issues.
