Public bug reported:
Not sure if this is a gdm3 or nvidia-graphics issue.
Ubuntu 20.04, gdm3
Nvidia GTX 1650, Nvidia proprietary driver
After a fresh boot I can switch users from my X session with no problem in the
first, say, 1 hour.
If I use the system for a day switching user takes me to a blank screen with
only the mouse cursor for a few minutes until the logon screen does appear.
ssh'ing into my box while this happens shows Xorg at 100% cpu
utilisation and the following being appended to /var/log/Xorg.0.log (and
equiv in /var/log/syslog) at crazy speed:

If I disconnect my monitor by pulling out the hdmi cable from the nvidia
card and reconnect it the logon screen comes up immediately and all is
good.
Otherwise I have to wait a few minutes and the logon screen will
eventually come up. The message in /var/log/Xorg.0.log I get after
unplugging is:
