This article provides step by step guide to completely remove existing NVIDIA drivers and reinstall specific version of the NVIDIA driver on the Ubuntu system

Prerequisites

1. Administrative (sudo) access to the Ubuntu system.
   
2. Internet access to download the necessary packages.

Steps

1. Remove Existing NVIDIA Drivers
   First, we need to remove any existing NVIDIA drivers from the system.
   sudo apt-get remove --purge '^nvidia-.*'
2. Clean Up Unused Packages
   
   Remove any packages that are no longer needed.
   

   sudo apt autoremove
   Clean up the local repository of retrieved package files.

   sudo apt autoclean
3. Remove NVIDIA-related Files
   Next, we need to remove any remaining NVIDIA-related files from various directories.
   sudo rm -rf /usr/local/cuda*
   sudo rm -rf /usr/local/nvidia*
   sudo rm -rf /usr/lib/nvidia*
   sudo rm -rf /usr/include/nvidia*
   sudo rm -rf /etc/systemd/system/nvidia*
4. Add the Graphics Drivers PPA
   To ensure we have access to the latest drivers, add the graphics drivers PPA (Personal Package Archive).
   sudo add-apt-repository ppa:graphics-drivers/ppa
5. Update the Package List
   Update the package list to include the latest drivers from the added PPA.
   sudo apt update
6. Install the Specific NVIDIA Driver Version
   Install the specific version of the NVIDIA driver. In this example, we are installing version 535.161.08-0ubuntu2.22.04.1.
   sudo apt install nvidia-driver-535-server=535.161.08-0ubuntu2.22.04.1
7. Check the APT Sources 
   
   Verify the /etc/apt/sources.list file  to ensure all repositories are correctly listed .If not edit your sudo nano /etc/apt/sources.list to ensure the updates and security repositories are enabled. It should contain lines similar to these:
   
   deb http://archive.ubuntu.com/ubuntu jammy main restricted
   deb http://archive.ubuntu.com/ubuntu jammy-updates main restricted
   deb http://archive.ubuntu.com/ubuntu jammy universe
   deb http://archive.ubuntu.com/ubuntu jammy-updates universe
   deb http://archive.ubuntu.com/ubuntu jammy multiverse
   deb http://archive.ubuntu.com/ubuntu jammy-updates multiverse

   deb http://security.ubuntu.com/ubuntu jammy-security main restricted
   deb http://security.ubuntu.com/ubuntu jammy-security universe
   deb http://security.ubuntu.com/ubuntu jammy-security multiverse
