Ubuntu 20.04 LTS black screen after login after installing Nvidia's driver v. 465.31

The problem: I receive black screen after installing Ubuntu 20.04 LTS / 18.04 LTS by either a normal installation or a minimal installation + manually installing the NVIDIA’s driver 465.31 (or 460 where in the minimal installation I get an unknown display with 1024x768 resolution). I walked along the NVIDIA docs step by step in NVIDIA Driver Installation Quickstart Guide :: NVIDIA Tesla Documentation.

I tried several fixes with no success:

  • changed to lightdm display.
  • confirmed nvidia-prime is installed.
  • delete /etc/X11/xorg.conf.

but nothing seems to solve the problem. I have to uninstall the driver each time again on the recovery mode to be able to boot normally into low resolution.

I can also see the driver is installed with ‘nvidia-smi’ in recovery mode.

Windows works fine though.

Thanks for any help.
