After upgrading 18.04 LTS to 20.04 LTS X started to freeze at the login when using NVIDIA's driver 440.82 or 440.100.

When investigating log files, the following was found in Xorg.0.log:

"(EE) NVIDIA(GPU-0): Failed to acquire modesetting permission."

To prevent the freeze, adding kernel command line parameter "nvidia_drm.modeset=1" was required.

Nouveau driver had already been blacklisted, as it has never been stable on the computer in question.
