** quick notes

I'll add more soon; link other report(s; 1 kubuntu, 1 ubuntu) & maybe mark duplicate

NOTE: this or like issue is experienced with Ubuntu (GNOME) & Kubuntu (KDE) so it's not surprising. It does not occur on Xubuntu & Lubuntu though.

Daniel (vanvugt) has suggested this box should only be used for 20.04; bugs in nouveau are difficult for Ubuntu to track down.. but this box is what I have for QA-installs.

Install worked flawlessly except the adjust.screens.to.match.my.setup which I consider part of system shakedown..

Of NOTE: I can click the 'hide all windows & show desktop' and screen muck up was gone in an instant; hit it again & windows were returned & usable.
