Curiously the music continues to play (and e.g. sound from youtube video continues to be played even though the video itself freezes and no longer animates on-screen). It appears that the freeze happens quite randomly; I am not able to figure out what it's caused by. Sometimes it's caused by launching the Snap Chromium, or perhaps by a notification shown, but I do not know for sure. I also tried to hunt system logs and/or systemd gnome-shell logs, but I failed to discover some kind of crash dump. Curiously the Ctrl+Alt+F2 key combo stops working. That leads me to believe that it's some kind of kernel+nouveau crash, but I can't seem to discover any kernel panic in the system logs. After the gnome-shell freezes, the numlock light still responds to numlock key presses. However, mashing Ctrl+Alt+Del has no effect, so I'm only able to reboot via Alt+Sysrq+s u b.
