Been a while, but I just got hit with the "X, keyboard and mouse all freeze at once" - no getting to another VT. But I could ssh in from another machine. As always when this happens, nothing useable in any logs. Trying to `sudo kill -9 pidof X`, etc.. did absolutely nothing. After a reboot, I went googl'ing for sysrq, which led me to discover that (a) my keyboard is not mapped for it (fixable), (b) /proc/sysrq-trigger would be just fine over ssh and (c) I can't figure out where output of sysrq's like 'l' (backtrace for all CPUS) goes - if only so that I can tell I've got things set up properly. The web says "goes to console", but on Leap, where the heck is that? If it is hidden by X on 1, is there a way to get it into the journal (journalctl)? So, I hereby solicit advice on: 1) clever ways to kill things that are locking up my system from an ssh session 2) clever ways to use /proc/sysrq-trigger, esp. if I can figure out if it is even working... 3) Debugging any of the above. After a dozen of these over the past 5 years or so, with no trace left in logs, I've kind of given up, but hey.
