nvidia-smi is failing:

$ nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

There appears to be prior installation [attempts?] of nvidia on this machine. How do I clean this up?

$ sudo ubuntu-drivers autoinstall

    Typically you have to purge all old drivers first. If installed directly from nVidia with .run file, you need to remove that. If from Ubuntu repository sudo apt-get remove --purge nvidia-* Should not need ppa anymore as drivers included in Ubuntu repository: https://askubuntu.com/questions/61396/how-do-i-install-the-nvidia-drivers Uninstall the .run nVidia driver. https://askubuntu.com/questions/219942/how-to-uninstall-manually-installed-nvidia-drivers – oldfred Jun 08 '21 at 03:35
  • @oldfred I did a bunch of purges first. This is really a difficult [re-] install. I am going to go get some top pro's to do it – WestCoastProjects Jun 08 '21 at 03:41
