[xubuntu-users] Odd behaviour on laptop suspend/resume

I don't know if this is hardware, OS, or X.

I have been running Mint 20.2 on a Dell XPS 15 laptop for a few years 
and it's been fine. It's set to Suspend when the lid gets closed (both 
on power and on battery) and that's exactly what it was doing. Lifting 
the lid brought back the lock screen where I could give my password to 

Suddenly, about 4 months ago, lifting the lid brought back the screen I 
was working on, all windows visible, for about 1½–2 seconds, then it 
blanked and the power button flashed briefly, exactly like a shutdown.
But pressing the power button brought back the lock screen, and I could 
give my password and continue OK.

It was unexpected, but it didn't worry me unduly, even less when after 
about a month it went back to behaving as it ought.

Now it has started doing it again (about 2 weeks ago). There have of 
course been periodic apt upgrades, and of course I didn't note the dates 
because the change in behaviour wasn't a problem.

Has anyone else had this happen?
