Be pragmatic, use the binaries provided by nvidia and not the ones provided by Ubuntu.

Or use Suse, only distro that manages that well. Forget PopOS. Really, either binaries or Suse.

If someone else here is entrenched on Arch, do this: https://github.com/Frogging-Family/nvidia-all

If on Fedora, just use the binaries... trust me.

Hope this helps someone.
