It appears the same crash symptoms are still happening on Ubuntu 20.04 with xserver-xorg-video-nouveau package and Nvidia GT240 chipset.

It happens after half an hour to a couple of hours usage and affects installed systems as well, until they are switched to the proprietary driver. This is a well known bug in other trackers but I can't see it anywhere on Launchpad, so I'm reporting it and will add bug watches.
