Embracing Native NVIDIA Drivers on AlmaLinux: A New Era

The introduction of native NVIDIA driver support on AlmaLinux 9 and 10 marks a turning point for the operating system. Previously, users often had to resort to third-party repositories or manual driver installations, which could be complex and prone to issues. With this new support, AlmaLinux now provides a streamlined and officially sanctioned method for installing and managing NVIDIA drivers, ensuring greater stability, performance, and security. This is a significant boon for both individual users and organizations that depend on AlmaLinux in demanding environments. The fact that this wasn’t possible just 5 years ago, highlights the rapid evolution and increasing importance of open source contributions.

Key Advantages of Native Support

  • Simplified Installation: Forget about wrestling with complex driver installations. The official AlmaLinux repositories now contain NVIDIA drivers, making the process as simple as installing any other package.
  • Improved Stability: Official support means that the drivers are thoroughly tested and integrated with the AlmaLinux ecosystem, leading to greater stability and fewer compatibility issues.
  • Enhanced Performance: Native drivers are optimized for the AlmaLinux kernel, delivering the best possible performance for your NVIDIA GPU.
  • Automatic Updates: The drivers are updated through the standard AlmaLinux update mechanisms, ensuring that you always have the latest features and security patches.
  • Secure Boot Compatibility: This is a HUGE step forward. Signed kernel modules that make secure boot possible, allowing your AlmaLinux installations to retain their security posture, and keep signed kernel modules for NVIDIA.

Installing NVIDIA Drivers on AlmaLinux 9 and 10: A Step-by-Step Guide

Installing NVIDIA drivers on AlmaLinux 9 and 10 is now a straightforward process. Follow these steps to get started:

  1. Enable the Necessary Repositories:

    First, you need to enable the appropriate repositories that contain the NVIDIA drivers. This is typically done using the dnf package manager. Run the following commands:

    sudo dnf install epel-release
sudo dnf config-manager --add-repo https://developer.download.nvidia.com/compute/cuda/repos/almalinux9/x86_64/cuda-almalinux9.repo #replace almalinux9 with almalinux10 if needed.
sudo dnf clean all

    Important: Replace almalinux9 with almalinux10 if you are using AlmaLinux 10. These commands add the NVIDIA CUDA repository, allowing you to install the drivers and related tools.

  2. Install the NVIDIA Driver:

    Once the repositories are enabled, you can install the NVIDIA driver using dnf. The specific package name may vary depending on the driver version you want to install. To install the latest driver, use the following command:

    sudo dnf module install nvidia-driver:latest-dkms

    This command installs the latest available NVIDIA driver along with DKMS (Dynamic Kernel Module Support). DKMS ensures that the driver is automatically rebuilt when the kernel is updated, preventing compatibility issues.

  3. Reboot Your System:

    After the installation is complete, reboot your system to load the new NVIDIA driver.

    sudo reboot

  4. Verify the Installation:

    After rebooting, verify that the NVIDIA driver is correctly installed by running the following command:

    nvidia-smi

    This command displays information about your NVIDIA GPU, including the driver version, GPU temperature, and memory usage. If the command runs successfully and displays the information, the driver is installed correctly.

Configuring CUDA for Accelerated Computing

CUDA (Compute Unified Device Architecture) is a parallel computing platform and programming model developed by NVIDIA. It allows you to use your NVIDIA GPU for general-purpose computing tasks, such as machine learning, scientific simulations, and video processing.

Installing CUDA Toolkit

To use CUDA, you need to install the CUDA Toolkit. The toolkit includes the CUDA compiler, libraries, and tools needed to develop and run CUDA applications.

  1. Download the CUDA Toolkit:

    Download the CUDA Toolkit from the NVIDIA website. Make sure to select the correct version for your operating system and architecture. Alternatively, use dnf:

    sudo dnf install nvidia-driver cuda

  2. Set Environment Variables:

    After installing the CUDA Toolkit, you need to set the environment variables to point to the CUDA installation directory. Add the following lines to your ~/.bashrc or ~/.zshrc file:

    export CUDA_HOME=/usr/local/cuda
export PATH=$CUDA_HOME/bin:$PATH
export LD_LIBRARY_PATH=$CUDA_HOME/lib64:$LD_LIBRARY_PATH

    Save the file and source it to apply the changes:

    source ~/.bashrc  # or source ~/.zshrc

  3. Verify CUDA Installation:

    Verify the CUDA installation by running the following command:

    nvcc --version

    This command displays the version of the CUDA compiler. If the command runs successfully, CUDA is installed correctly.

Addressing Common Issues and Troubleshooting

While the installation process is generally straightforward, you may encounter some issues. Here are some common problems and their solutions:

  • Black Screen After Installation:

    This can happen if the NVIDIA driver is not compatible with your system or if there is a conflict with other drivers. Try booting into recovery mode and uninstalling the NVIDIA driver. Then, reinstall the driver using the steps outlined above.

  • NVIDIA-SMI Command Not Found:

    This indicates that the NVIDIA driver is not installed correctly or that the environment variables are not set up correctly. Verify that the driver is installed and that the PATH environment variable includes the directory containing the nvidia-smi command.

  • CUDA Applications Not Running:

    This can happen if the CUDA Toolkit is not installed correctly or if the environment variables are not set up correctly. Verify that the CUDA Toolkit is installed and that the CUDA_HOME, PATH, and LD_LIBRARY_PATH environment variables are set correctly. Ensure you have the compatible NVIDIA driver installed for the CUDA toolkit version.

  • Secure Boot Issues:

    If you encounter issues with Secure Boot, ensure that the NVIDIA kernel modules are properly signed. The AlmaLinux project provides signed kernel modules, but you may need to configure your system to trust the AlmaLinux signing key. Follow the instructions in the AlmaLinux documentation to enroll the key.

Leveraging NVIDIA GPUs for Machine Learning

NVIDIA GPUs are widely used for machine learning tasks, thanks to their parallel processing capabilities and the CUDA platform. Here’s how to set up your AlmaLinux system for machine learning:

  1. Install the Necessary Libraries:

    Install the popular machine learning libraries, such as TensorFlow, PyTorch, and scikit-learn. These libraries can be installed using pip:

    pip install tensorflow
pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118
pip install scikit-learn

  2. Configure TensorFlow and PyTorch to Use the GPU:

    TensorFlow and PyTorch can automatically detect and use NVIDIA GPUs if the CUDA Toolkit and the NVIDIA driver are installed correctly. You may need to configure these libraries to use the GPU explicitly by setting the appropriate environment variables or using the library-specific configuration options.

  3. Test Your Setup:

    Test your machine learning setup by running a simple program that uses the GPU. For example, you can use TensorFlow to train a simple neural network on the MNIST dataset.

Gaming on AlmaLinux with NVIDIA Graphics

With native NVIDIA driver support, gaming on AlmaLinux has become significantly more enjoyable. Here are some tips for optimizing your gaming experience:

  1. Install Steam:

    Install Steam, the popular gaming platform, using the following command:

    sudo dnf install steam

  2. Configure NVIDIA Settings:

    Use the NVIDIA X Server Settings tool to configure your NVIDIA GPU for gaming. This tool allows you to adjust various settings, such as the resolution, refresh rate, and anti-aliasing level.

  3. Install Game-Specific Drivers:

    Some games may require specific drivers or configurations. Check the game’s documentation for any specific instructions.

The Future of NVIDIA Support on AlmaLinux

The AlmaLinux project is committed to providing ongoing support for NVIDIA drivers. We can expect to see further improvements in the future, including:

  • Support for New NVIDIA GPUs: The AlmaLinux project will continue to add support for new NVIDIA GPUs as they are released.
  • Optimizations for Specific Workloads: The project may introduce optimizations for specific workloads, such as machine learning and gaming.
