On my system with Nvidia 510 drivers I found that if I'm logged in and
lock the session another user can't login. I reset the 2nd user's
account to verify that if I login and lock my session they can't login.
I found this in permission error in the logs.
May 09 21:58:20 x1 gnome-shell[17718]: Failed to start X Wayland: Wrong
ownership for directory "/tmp/.X11-unix"
I've confirmed that /tmp/.X11-unix is owned by the 1st user, so
something seems to be causing the system to use the same tmp directory
for both users.
