Consider this sorted. I changed the monitor for another LG Flatron from our old
computer, and it is behaving well. I guess the old monitor is giving up.

Just now when this occurred, I switched off the monitor, and after a few
seconds switched it back on and the screen came back to life. So the problem
isn't with Kubuntu, unless there is something in the graphics causing it. Maybe
my screen is getting old. It's random because it didn't occur at all
yesterday, and has happened a few times today.

If I leave my Kubuntu 20.04 for awhile, I have usually left Thunderbird and
Vivaldi up, and when I come back and try and do something the computer goes off
into never-never land, the screen goes blank, and I can hear the HD crunching,
and it needs the power button hold down to shut it down.
I think that this has happened after a boot up, if I have left it for awhile
and I hit T'bird and Vivaldi one after the other to bring them up.
Any thoughts on where I should look to track this problem?
I am tempted to bleachbit the computer, or to replace Vivaldi with Opera on the
offchance that Vivaldi is the cause.
Cheers,
