Understanding Your Hardware and Fedora System

Before we embark on the driver installation journey, it’s crucial to have a clear understanding of your system’s components and how Fedora Workstation 42 interacts with them. This foundational knowledge will not only prevent potential conflicts but also allow for a more informed approach to the entire process.

Identifying Your NVIDIA Graphics Card

The first and most vital step is to accurately identify the specific NVIDIA graphics card installed in your system. Fedora Workstation 42 is designed to be flexible, but driver compatibility is strictly hardware-dependent.

  • Using the Command Line: The most reliable method is to use the terminal. Open your terminal application and execute the following command:

    lspci | grep -i nvidia

    This command will scan your PCI devices and filter for any entries containing “NVIDIA.” The output will typically provide you with the exact model of your NVIDIA GPU, such as “NVIDIA Corporation GP107 [GeForce GTX 1050 Ti]” or “NVIDIA Corporation TU104 [GeForce RTX 2070]”. Knowing this precise model is indispensable for selecting the correct driver.

  • Graphical System Information Tools: Fedora also offers graphical tools for system information. You can usually find these under your system settings or by searching for “System Information” or “Hardware” in your application menu. These tools often provide a user-friendly interface to view your hardware details, including your graphics card.

Verifying Your Fedora Workstation 42 Installation

Ensuring your Fedora Workstation 42 installation is up-to-date and free from existing driver conflicts is equally important. A clean and updated system forms the bedrock of a successful driver installation.

  • System Updates: It is imperative to ensure your system is fully updated before proceeding. Open your terminal and run:

    sudo dnf upgrade --refresh

    This command will synchronize your package manager’s metadata and upgrade all installed packages to their latest versions. This process is critical for resolving any potential compatibility issues with newer kernel versions or system libraries that the NVIDIA drivers might depend on.

  • Checking for Existing NVIDIA Drivers: If you previously attempted an installation and encountered problems, there might be residual NVIDIA driver components on your system. It’s best to ensure these are completely removed. While the safe mode removal is a good start, a thorough check is advisable.

    dnf list installed | grep nvidia

    If you see any NVIDIA-related packages listed here, and you are aiming for a fresh installation, you might consider removing them. However, we will focus on a clean installation method that usually bypasses the need for manual removal if done correctly from the start. The recommended method below will handle any previous installations gracefully.

The Importance of the Correct Kernel Version

NVIDIA drivers are deeply integrated with the Linux kernel. As Fedora Workstation 42 is a rolling release with frequent kernel updates, ensuring that the driver installation method is kernel-module-aware is paramount. This is where akmod or kmod packages typically come into play, as they are designed to build kernel modules that are compatible with your currently running kernel.

The Preferred Method: RPM Fusion and akmod-nvidia

For Fedora Workstation, the RPM Fusion repository is the universally recommended source for proprietary drivers, including those for NVIDIA graphics cards. RPM Fusion provides expertly packaged software that is often not available in the official Fedora repositories due to licensing restrictions. The akmod-nvidia package from RPM Fusion is specifically designed to build NVIDIA kernel modules that are compatible with your system’s current kernel, ensuring a dynamic and robust solution.

Enabling the RPM Fusion Repositories

Before you can install the NVIDIA drivers, you must enable the RPM Fusion repositories. Fedora Workstation 42 requires both the free and non-free (or “tainted”) repositories.

  1. Download the RPM Fusion Repository Configuration Files: Open your terminal and navigate to a temporary directory where you can download the files.

    cd /tmp
wget https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
wget https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
    • Explanation: The $(rpm -E %fedora) command dynamically determines your Fedora version and fetches the correct repository configuration files. This ensures you get the packages specifically built for Fedora Workstation 42.

  2. Install the Repository Configuration Files: Once downloaded, install these files using dnf.

    sudo dnf install rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm
    • Explanation: Installing these packages registers the RPM Fusion repositories with your system’s package manager.

  3. Clean and Update the Package Cache: After enabling the new repositories, it’s good practice to clean your DNF cache and refresh your package lists.

    sudo dnf clean all
sudo dnf upgrade --refresh
    • Explanation: This ensures that DNF is aware of the packages available from RPM Fusion and that your system is fully synchronized.

Installing the NVIDIA Drivers and Dependencies

With RPM Fusion enabled, we can now proceed with installing the NVIDIA drivers. The akmod-nvidia package is our primary target, but it requires certain dependencies to function correctly.

  1. Install the Correct akmod-nvidia Package: Fedora Workstation 42 often benefits from the specific akmod-nvidia package that matches the driver series. While the generic akmod-nvidia usually works, there are sometimes specific versions available for newer hardware.

    • General Installation:

      sudo dnf install akmod-nvidia

    • For Newer Hardware (if the above doesn’t suffice): You might need to install a specific version. You can list available NVIDIA drivers with:

      dnf search akmod-nvidia

      Then install the most appropriate one, for example: sudo dnf install akmod-nvidia-535.104.09. However, for most users, the general sudo dnf install akmod-nvidia is sufficient and the system will select the best available driver.

  2. Install Necessary Dependencies: For the NVIDIA drivers to function correctly, particularly for features like CUDA and PRIME support, you’ll need to install additional packages.

    sudo dnf install xorg-x11-drv-nvidia-cuda
    • Explanation: The xorg-x11-drv-nvidia-cuda package provides the necessary CUDA libraries and headers, which are essential for GPU computing tasks and often improve overall system stability and performance.

  3. Handle the Nouveau Driver (Kernel Module Blacklisting): Fedora Workstation 42 uses the open-source nouveau driver by default for NVIDIA cards. To ensure the proprietary NVIDIA driver is loaded and used exclusively, the nouveau driver needs to be blacklisted. The akmod-nvidia installation process typically handles this automatically by creating a configuration file in /etc/modprobe.d/. However, it’s good to be aware of this process.

    • Manual Blacklisting (if needed): If you encounter issues, you can manually ensure nouveau is blacklisted. Create or edit a file like /etc/modprobe.d/blacklist-nouveau.conf with the following content:

      blacklist nouveau
options nouveau modeset=0

      And then rebuild your initramfs:

      sudo dracut --force

    • Explanation: Blacklisting prevents the nouveau driver from loading at boot. options nouveau modeset=0 is often included to further ensure it doesn’t interfere. dracut --force updates the initial RAM disk image with the new blacklisting rules. However, the akmod-nvidia installation from RPM Fusion is designed to do this for you, so manual intervention is rarely required if you follow the recommended steps.

Rebooting and Verifying the Installation

After the installation process completes, a system reboot is essential for the new drivers and kernel modules to be loaded.

  1. Reboot Your System:

    sudo reboot

  2. Verify Driver Loading: Once your system has rebooted, you can verify that the NVIDIA drivers are loaded and active.

    • Using nvidia-smi: This is the most definitive way to check. Open your terminal and run:

      nvidia-smi

      If the NVIDIA drivers are installed correctly, this command will display detailed information about your NVIDIA GPU, including its model, driver version, CUDA version, and current GPU utilization. If you receive an error or no output, the drivers are not loaded correctly.

    • Using glxinfo: This tool can help verify if OpenGL is using the NVIDIA driver. You may need to install mesa-utils if you don’t have it already:

      sudo dnf install mesa-utils

      Then run:

      glxinfo | grep "OpenGL renderer"

      The output should show your NVIDIA GPU model, for example: OpenGL renderer string: NVIDIA GeForce RTX 3070/PCIe/SSE2.

    • System Settings: Fedora’s GNOME desktop environment usually provides a graphical way to check. Navigate to Settings -> About. Under “Graphics,” it should indicate that you are using your NVIDIA graphics card.

Troubleshooting Common Issues During Installation

Even with the best methods, occasional hiccups can occur. Here are solutions to common problems encountered during NVIDIA driver installation on Fedora Workstation 42:

  • “No screens found” or Black Screen After Reboot: This is often caused by the nouveau driver not being properly blacklisted, or a conflict with the display server (Xorg or Wayland).

    • Solution: Ensure nouveau is blacklisted as described above and rebuild the initramfs. If you are using Wayland (which is the default in Fedora Workstation 42), sometimes switching to Xorg can resolve immediate display issues. You can select Xorg from the login screen by clicking the gear icon before entering your password.

  • nvidia-smi Command Not Found: This indicates that the NVIDIA driver binaries are not in your system’s PATH, or the drivers themselves did not install correctly.

    • Solution: Double-check that the akmod-nvidia package and its dependencies were installed without errors. Re-run the installation command.

  • System Slowdowns or High CPU Usage: As you experienced, this is a serious indicator of a driver conflict or an improperly configured driver.

    • Solution: The most likely culprit is a conflict with the nouveau driver or an incomplete installation. Boot into a recovery mode or a TTY (text console) by pressing Ctrl+Alt+F2 (or F3-F6), log in with your username and password, and then perform the steps to remove the potentially problematic NVIDIA drivers and reboot. After that, meticulously follow the RPM Fusion installation steps again, ensuring each command executes without error.

  • Secure Boot Issues: If you have Secure Boot enabled in your UEFI settings, it might prevent the NVIDIA kernel modules from loading because they are not signed.

    • Solution: You will either need to disable Secure Boot in your UEFI/BIOS settings or sign the NVIDIA kernel modules yourself. Disabling Secure Boot is generally the simpler solution for most users. To sign the modules, you would need to generate keys and configure mokutil to enroll them, which is a more advanced topic. For most Fedora users, disabling Secure Boot is the recommended path if this issue arises.

Advanced Configurations: PRIME and Multi-GPU Setups

For laptops with both integrated graphics (like Intel or AMD) and a dedicated NVIDIA GPU, or for desktop users with multiple GPUs, configuring NVIDIA PRIME is essential for optimal performance and power management.

Understanding NVIDIA PRIME

NVIDIA PRIME is a technology that allows the system to use different GPUs for different tasks, or to render graphics on one GPU and display them on another. This is particularly useful for laptops, where you can use the power-efficient integrated graphics for everyday tasks and switch to the high-performance NVIDIA GPU for demanding applications like gaming or 3D rendering.

Configuring PRIME with Fedora Workstation 42

The installation of akmod-nvidia and xorg-x11-drv-nvidia-cuda from RPM Fusion typically sets up the necessary configurations for PRIME.

  1. Ensure the xorg-x11-drv-nvidia-cuda package is installed: This package includes essential components for PRIME.

  2. Verify PRIME Status: You can check if PRIME is configured correctly by looking at your system settings or by using specific commands. In GNOME, under Settings -> About, you should see indications of your graphics setup.

  3. Switching Between GPUs (PRIME Profiles): Fedora Workstation 42, when configured with the NVIDIA driver, often provides a GNOME extension or a system setting to switch between GPU profiles:

    • Hybrid Graphics: Uses both integrated and NVIDIA GPUs.
    • Integrated Graphics: Uses only the power-efficient integrated GPU.
    • NVIDIA (Performance Mode): Forces the use of the NVIDIA GPU for all applications.

    If you don’t see these options readily available, ensure you have the nvidia-settings package installed:

    sudo dnf install nvidia-settings

    You can then launch nvidia-settings from the terminal or your application menu to configure GPU selection and other display settings.

  4. Launching Applications with the NVIDIA GPU: For specific applications that you want to run exclusively on the NVIDIA GPU, you can use the prime-run command:

    prime-run application_name

    For example, to launch a game:

    prime-run steam

    This command ensures that the application is directed to the NVIDIA GPU, providing maximum performance.

Maintaining Your NVIDIA Driver Installation

Keeping your NVIDIA drivers up-to-date is crucial for security, performance, and compatibility with new software and kernel releases.

Updating Your NVIDIA Drivers

Since you’ve installed drivers using dnf from RPM Fusion, updating them is as simple as updating your entire system.

  1. Regular System Updates: Periodically run the following command to update all your packages, including the NVIDIA drivers:

    sudo dnf upgrade --refresh

    When a new NVIDIA driver version is released and packaged by RPM Fusion, this command will automatically fetch and install it. The akmod-nvidia package will then rebuild the kernel modules for your new kernel version upon the next boot.

When to Reinstall or Rebuild Modules

In rare cases, especially after major system upgrades or significant kernel changes, you might encounter issues where the NVIDIA kernel modules don’t get rebuilt correctly.

  • After Kernel Updates: While akmod is designed to handle kernel updates automatically, sometimes manual intervention might be needed. If you experience graphical glitches or the nvidia-smi command fails after a kernel update, try rebuilding the modules:

    sudo akmods --force
sudo dracut --force

    Then reboot your system.

  • Troubleshooting Driver Issues: If you suspect your NVIDIA drivers are corrupted or misconfigured, the best approach is to remove them cleanly and reinstall using the RPM Fusion method described earlier.

    To remove:

    sudo dnf remove akmod-nvidia xorg-x11-drv-nvidia-cuda
sudo dnf autoremove

    Then reboot, and proceed with the installation steps from Section 2.
