ok, i've finally had my computer lock up again while i've set up the core dumps and i was hoping that i'd get an actual core dump file to help narrow things down to a specific programs, but no luck with that at all.
system is running Debian Testing, updates applied each morning. desktop is MATE. the only messages i can find are in the Xorg.old log and they look like: ===== [ 2341.978] (EE) event4 - Logitech K840 Mechanical Corded Keyboard: client bug: event processing lagging behind by 27ms, your system is too slow ===== the symptoms are that as i am typing the keyboard completely stops responding and the mouse too, the system is then hung. nothing updates or changes. the clock, network, etc. all stuck. when i search for this kind of problem on the internet i come up with: https://itectec.com/ubuntu/ubuntu-why-am-i-getting-event-processing-lagging-behind-msg-in-ubuntu-20-10/ which says ignore it while the following two give me the hope that it is some kind of bug that might get fixed. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968093 https://gitlab.freedesktop.org/xorg/driver/xf86-input-libinput/-/issues/46 i'm not sure i can help at all with debugging this further, but since others might be seeing this message and wondering what is going on i'll post this anyways. songbird
