Public bug reported:

Lubuntu 20.04 daily QA-test on
hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)


Displays have been adjusted to my setup (one above the other) but I doubt this 
is an issue

I suspended system, waited, pressed ESC to wake & it resumed to
xscreensaver, but 'flurry' was chopped and showing white/black patches
on display as if glitching... I touched mouse & my session removed.

opened xscreensaver & preview - yep glitch there too... changed to
'fliptext' & no issues, but flurry is very jerky with image switching to
almost-blocky-bad-signal (I think it's alternating between showing
something else, text; it seems to vary on what I've had on screen before
screensaver is loaded & continuing to show xscreensaver..)

attempts to screengrab with delay have failed (just capturing black
screen)..

`lshw -C video` reports I'm using nouveau.

This issue may not relate to 'xserver-xorg-video-nouveau', but I suspect
it's there. I've performed this test a number of times on various boxes
without issue (will do so again once I shutdown this).
