Public bug reported:
I am testing Ubuntu 20.04. This system has an NVidia GPU, with nvidia-
driver 440.64.
With Linux kernel 5.4.0-18, I can login successfully to an X session (default
GNOME).
With Linux kernel 5.4.0-21, I fail to login to an X session. When I put my
password and press Enter to login, the screen blanks, and within a second
returns back to the login screen.
With Linux kernel 5.4.0-21 and Wayland session, it works and I can login.
