Public bug reported: This issue appeared first under 21.04, and I (wrongly) suspected a bug in the window manager or graphics stack. I posted on askubuntu at
https://askubuntu.com/questions/1346317/ubuntu-21-04-and-21-10-lock- hard-with-basic-gui-redrawing-using-standard-intel-g and even offered a bounty but no luck. I then hopen 21.10 may solve it, but alas, no. At issue is a fairly immediate system lock as soon as I use Chrome or Slack and switch desktops. It typically locks the machine with minutes of a reboot -- making it unuseable under GUI. On the other hand, I kept it running 'headless' (just ssh'ed in from byobu running on my desktop) for a month so I had some reason to believe the hard ware was not at fault. Now, more recently, I realized that I had not tried an older kernel, and indeed under 4.13.0-46-generic, still installed from an older relese, everything runs fine! I would be happy to help debug if you pointers or test builds.
