Yes. Thanks a lot, Dotan. I didn't know about this. Very useful indeed!

So how do you use that, if, as you say, the keyboard doesn't respond?

SysRq is hardwired into the kernel. If the kernel didn't panic, SysRq
still works even if X stopped processing keyboard events. And from the
sound of it, the kernel did not panic in this case since the mouse still
moves, so the kernel must be running.

Interesting, because (some months back) I have been in the same situation and
tried the SysRq 'magic keys', just in case, but without success.

It must be enabled in the kernel configuration. If the file
"/proc/sysrq-trigger" doesn't exist, you don't have it enabled.
