Working on GPU-accelerated projects requires keeping your CUDA toolkit and driver versions aligned. For CUDA 12.8, a minimum driver version on Linux is essential to ensure compatibility and smooth performance. Without the proper driver, you may face installation issues or reduced GPU efficiency. This guide walks you through installing the NVIDIA CUDA toolkit on Ubuntu 22.04, from updating system packages to setting up the right driver. By following the documented steps, you can prepare your environment for deep learning, AI workloads, and other compute-intensive applications. The instructions also highlight how to verify the installation and configure environment variables correctly. With CUDA 12.8 installed and the required driver in place, your Linux system will be ready to leverage GPU acceleration for maximum performance.
