Made some progress. Thanks for your replies!

Thank you Paul. Yes, I too remember that screensaver that would divide
the display into many little squares and then let them wander around.
The display crash I have been having from time to time is similar to
that effect only with smaller squares. I checked and see that
Screensaver is turned off, and also see that Screensaver does not have
that particular creative effect available these days. I am running a
fairly default Xubuntu 20.04 Focal. Aha! a new crash happened last
night just as I opened the Screensaver app that is turned off. No
display dissolution though, just a frozen display. Did another hard
reset with the power button and went to bed. This morning, so far no
crash.

> top and ps

Thank you Rick. I had forgotten top. Interesting tool. I have a 27
inch monitor, so room enough to watch top in a separate window, while
I do things in browser in another window. So far no memory problems. I
have 16 GB of ram and 12 GB free:

MiB Mem :  15964.2 total,  12101.2 free,   1469.5 used,   2393.6 buff/cache

Thank you Tony. I do have that installed. 'sudo apt show
xserver-xorg-video-intel' tells me also that this intel driver is not
recommended for newer computers (ca. 2007 and newer),

"The use of this driver is discouraged if your hw is new enough (ca.
 2007 and newer). You can try uninstalling this driver and let the
 server use its builtin modesetting driver instead."

I'm going to remove it now with 'sudo apt remove xserver-xorg-video-intel'.

I'm also doing 'sudo apt autoremove' because why not.

Rick, in Xunubtu focal I had found that the place to set prefered
browser is Settings > Prefered Applications. Was just an observation.
Then the display crash happened again after I had switched from
Firefox to Chromium. You are right, browser is not logically going to
crash the display. I was reaching at straws.

I mostly only use Linux when I am tinkering on the back end of the
teflpedia.com wiki that I run on a shared webhost, which tinkering I
do less and less as the years go by. It is nearing time to upgrade the
Mediawiki software there again. So I'm kicking the tires on my Linux
installation. Don't need my computer freezing up on me when I'm ssh'ed
into the webhost.

Thank you Paul, Rick and Tony!

Roger            *I think every time I do a fresh install of Linux, I
will want to 'sudo apt remove xserver-xorg-video-intel' till some day
in the future when that driver is no longer auto-installed.*
