Installing CUDA Drivers on Ubuntu 22.04

Introduction

Installing CUDA drivers on Ubuntu 22.04 is straightforward. Follow this step-by-step guide for a smooth installation.

Step 1: Update Your System

Start by updating your system. Open the terminal and run:

sudo apt update
sudo apt upgrade -y

Keeping your system updated ensures security and stability.

Step 2: Install Dependencies

Next, install the required dependencies with the following command:

sudo apt install build-essential dkms

These packages help in building and managing kernel modules.

Step 3: Add NVIDIA Repository

Add the NVIDIA package repository to your system. This step is crucial for downloading CUDA:

wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-ubuntu2204.pin
sudo mv cuda-ubuntu2204.pin /etc/apt/preferences.d/cuda-repository-pin-600

sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/3bf863cc.pub

sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/ /"

Step 4: Install CUDA Toolkit

Now, install the CUDA toolkit. This step also installs the necessary drivers:

sudo apt update
sudo apt install cuda -y

This command installs CUDA and its components.

Step 5: Reboot Your System

After installation, reboot your system to load the new drivers:

sudo reboot

Rebooting ensures the new drivers are active.

Step 6: Verify Installation

Once your system reboots, verify the installation. Check if the drivers and CUDA toolkit are properly installed:

nvidia-smi
nvcc --version

If nvidia-smi shows GPU information and nvcc --version displays the CUDA version, your installation is successful.

Optional: Set Environment Variables

Setting environment variables can help in locating CUDA tools. Add the following lines to your ~/.bashrc or ~/.zshrc file:

export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

Source the file to apply the changes:

source ~/.bashrc  # or source ~/.zshrc if you use zsh

Conclusion

Installing CUDA drivers on Ubuntu 22.04 is simple. Follow these steps to ensure a smooth installation. Keep your system updated and verify each step for success. With these drivers, you can harness the power of CUDA on your NVIDIA card.
