It won't allow me to select anything in Additional Drivers which says: The device is using a manually installed driver.

enter image description here

I am unable to switch back to the Nvidia proprietary driver after switching to the open source driver.

  1. Remove all the nvidia packages.

    sudo apt update
sudo apt-get remove '^nvidia'
sudo apt autoremove

  2. If you have added an Nvidia PPA to /etc/apt/sources.list remove that PPA by prefacing its line in sources.list with a # to comment it out. Run sudo apt update to refresh the list of available software.

  3. Reboot with sudo reboot

  4. Run the following command to install the correct proprietary Nvidia driver.

    sudo ubuntu-drivers install && sudo reboot

    The install option of ubuntu-drivers installs drivers that are appropriate for automatic installation including their dependencies. This would normally include the nvidia-prime package (tools to enable NVIDIA's Prime). Then you will have an Nvidia X Server Settings icon in the Dash, and there in the left pane of Nvidia X Server Settings you can find PRIME profiles.

  • After doing this my laptop would no longer boot. YMMV. – Ade Miller Aug 01 '22 at 21:36
  • @AdeMiller If your laptop no longer boots, boot into Recovery mode and uninstall the Nvidia proprietary graphics drivers with sudo apt update && sudo apt-get remove '^nvidia' && sudo apt autoremove && sudo reboot – karel Aug 01 '22 at 22:24
