Unfortunately- - - - here - - - - a reboot means the use of about 30 minutes
in using xrandr to connect monitors 3 and 4 (even without the HDMI I'm
working on) and then setting up everything else on my system (only 20 desktops
and almost all of the them are loaded) so reboots are used as seldom as
possible.

Had done apt upgrade so now am on a 5.10 kernel. (Maybe that will change
some things - - - here's hoping!!)
Did a reboot.

Suggestions?
