It was: > Debian Bullseye with latest Mate as DM. Sorry for my error! Does the timestamp on the final message in ~/.xsession-errors correlate with the Firefox lockup? Another thought: according to the GNOME project [1], ~/.xsession-errors is deprecated and we should look in the systemd journal now [2]. That link [1] has instructions to inspect journalctl as user, but I would probably also look as root if I have that access on the machine. These are just non-targetted ideas for troubleshooting, I hope someone else has better suggestions to help you. [1] https://help.gnome.org/admin/system-admin-guide/stable/session-debug.html.en [2] Although GNOME probably considers that X Windows is deprecated too, and we should use Wayland, or something, but I'm generally a late adopter of operating system changes so I don't know anything about that :)
