*Update* - on an earlier attempt to keep the screen on, I'd set the

screensaver was subsequently disabled, it seems this 3 hour time was
still having some affect, as the screen was indeed going black after
three hours. I've now set that timer to 999 minutes (over 16 hours)
which should suffice for most days. Screensaver then disabled again.
I've never had this problem before. Just set everything related to
display to off or never and it's been fine. If anyone has any more
thoughts, I'll be happy to hear them as I feel the 999 minutes is an
inelegant fudge/workaround.
Does this contain some clues?

In particular:
++++
sudo apt remove xfce4-screensaver
Next, disable start on login of xfce4-screensaver: In Xubuntu it is:
Whisker > Settings > Session and Startup > [] Screensaver (launch
screensaver and locker program)
Then, Whisker > Settings > Power Manager > Tab Display > Display power
management > ON (Yes, not OFF!) > move sliders to “Never”.
Finally:
xfce4-screensaver-command --exit
++++
