As requested I am adding the output from journalctl -b-1 > prevboot.txt Just to add some further info: * I reinstalled my Ubuntu system yesterday back to the same version (my wifi and bluetooth were not working and I could find no way to get them back, so this freeze has happened with a standard install of 20.04 LTS downloaded and installed yesterday afternoon and otherwise is working normally. * The freeze happened immediately after I installed and used Microsoft Teams (64 bit). That might be a coincidence. * The freeze often happens as I move the mouse from my external monitor to my main (laptop) screen.
** Attachment added: "This is the output from journalctl -b-1 > prevboot.txt" https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1933118/+attachment/5506986/+files/prevboot.txt -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1933118 Title: Screen freeze Status in gnome-shell package in Ubuntu: Incomplete Bug description: This bug appears to be a deadlock of some kind. It most often happens when I move the mouse (external USB mouse), but it has once happened when I left the computer logged in but idle and has sometimes happened in video conferences. When the problem occurs, the mouse cursor still moves and any audio continues being audible for a while, but the UI is frozen and unresponsive. The fan gets very loud as if the computer is doing a lot of work. If I try the 'REISUB' method of shutting down, it usually does not work. If I remote log in and do a shutdown, it takes several minutes to actually shut down - as if waiting for some process to time out. I haven't any obvious errors for this bug, and i don't know where to look for possible error messages. It is possible that if there is a deadlock, there is no error message, unless shutting down causes the process to generate an error message. The bug happens very often, sometimes several times a week. If you could tell me what commands to run when the problem occurs in order to gather more information, I can remote login and run those commands.
