So, you want to unleash the full power of your NVIDIA GPU on Ubuntu 22.04? Excellent choice! This guide will walk you through several methods, ensuring a smooth and successful installation. We’ll cover everything from the easiest point-and-click approach to the command-line wizardry that grants you finer control.

How to install NVIDIA Drivers on Ubuntu 22.04?

Installing NVIDIA drivers on Ubuntu 22.04 boils down to a few key approaches: using the GUI (Graphical User Interface) via the Software & Updates application, utilizing the command-line with the apt package manager, or employing the NVIDIA website drivers. Each method has its pros and cons, offering flexibility based on your comfort level and specific needs. Generally, the GUI method is recommended for beginners, while the command-line provides more advanced options, and the NVIDIA website is often used for very specific driver versions. Here’s a breakdown of each approach:

1. Using the Software & Updates Application (GUI):

This is the simplest method, ideal for most users.

Open the “Software & Updates” application. You can find it by searching in the Activities overview.
Navigate to the “Additional Drivers” tab. This tab lists available drivers for your hardware.
Select the desired NVIDIA driver. Ubuntu will suggest a recommended version, often the latest tested driver. You can choose between proprietary drivers (indicated by “nvidia-driver-xxx”) or the open-source “nouveau” driver. For optimal performance, choose a proprietary NVIDIA driver.
Click “Apply Changes” and wait for the installation to complete. You’ll be prompted to enter your password.
Restart your system. This is crucial for the new drivers to take effect.

2. Using the Command-Line (APT Package Manager):

This method offers more control and is often preferred by experienced users.

Update your package lists: Open a terminal and run sudo apt update.
Identify recommended drivers (optional but recommended): Run ubuntu-drivers devices. This command lists your NVIDIA GPU and suggests appropriate driver packages. Note the suggested driver.
Install the recommended driver: Use the command sudo apt install nvidia-driver-XXX, replacing XXX with the version number suggested by ubuntu-drivers devices. For example, if the recommended driver is nvidia-driver-525, the command would be sudo apt install nvidia-driver-525. If you didn’t run ubuntu-drivers devices, you can try installing the latest driver with sudo apt install nvidia-driver-latest.
Reboot your system: Type sudo reboot in the terminal.

3. Downloading and Installing Drivers from the NVIDIA Website:

This method is typically used when you need a specific driver version not available through the repositories or when facing compatibility issues. Be extremely cautious when using this method, as it requires disabling the Nouveau driver and can lead to system instability if done incorrectly.

Identify your GPU model and download the correct driver from the NVIDIA website. Go to the NVIDIA Driver Downloads page, manually select your product, and operating system, and download the appropriate driver.
Disable the Nouveau driver:
- Create a blacklist file: sudo nano /etc/modprobe.d/blacklist-nouveau.conf
- Add the following lines to the file: blacklist nouveau options nouveau modeset=0
- Save the file and exit (Ctrl+X, Y, Enter).
- Update the initramfs: sudo update-initramfs -u
Reboot your system into recovery mode: Restart your computer and press the Shift key repeatedly during startup to access the GRUB menu. Choose “Advanced options for Ubuntu” and then select a recovery mode kernel.
Drop to a root shell prompt: In the recovery menu, select “root Drop to root shell prompt”.
Remount the root filesystem with read/write permissions: mount -o remount,rw /
Navigate to the directory where you downloaded the NVIDIA driver: Use the cd command.
Make the driver executable: chmod +x NVIDIA-Linux-x86_64-XXX.XX.run (replace XXX.XX with the driver version number).
Run the installer: sudo ./NVIDIA-Linux-x86_64-XXX.XX.run
Follow the on-screen instructions. The installer will guide you through the process, asking questions about installation options.
Reboot your system: After the installation is complete, reboot your system.

Important Considerations:

Secure Boot: If you have Secure Boot enabled in your UEFI settings, you might encounter issues with NVIDIA drivers. You may need to disable Secure Boot or enroll the NVIDIA drivers’ signing key into your system’s firmware. Instructions for doing this are typically provided during the driver installation process.
Dependencies: The NVIDIA driver installation may require certain dependencies. The apt package manager should handle these automatically when using the apt install command. However, when using the NVIDIA website method, you might need to install dependencies manually if the installer reports missing libraries.
Kernel Headers: Ensure you have the correct kernel headers installed for your running kernel. This is usually handled automatically but can be a common point of failure.

Frequently Asked Questions (FAQs)

Here are some frequently asked questions to further clarify the NVIDIA driver installation process on Ubuntu 22.04.

1. How do I check which NVIDIA driver version is installed?

Open a terminal and run nvidia-smi. This command provides information about your NVIDIA GPU, including the installed driver version. Another method is to use the nvidia-settings application, which provides a graphical interface for managing NVIDIA drivers and settings.

2. What are the differences between the proprietary NVIDIA drivers and the Nouveau driver?

The proprietary NVIDIA drivers are developed and maintained by NVIDIA, offering superior performance and feature support, especially for gaming and demanding applications.
