It just happened again. I have reason to think that Firefox is
responsible, but at present, it's just a guess.
(One way I can tell it's happening is that I have an analog desktop clock running,
and don't maximize windows. As
long as the sweep-second hand's moving, I know the box hasn't froze.)
None of the Magic SysReq keys worked, and I ended up using the reset button again. After
rebooting and logging in,
I opened a terminal and as root ran
tail -f /var/log/messages
to watch what, if anything happened. I then used RightAlt-SysReq-r and saw the response
that the keyboard had been
set back to default. Using s caused an emergency sync, so I know that it works when
I'm in X, something I hadn't
tried before. Now we know, it's not just X that hangs
and for that is STRG+ALT+Print+K which kills X really
and bring you back to the login-screen which is way
more helpful than a complete reboot or reset
Kill all processes on the current virtual console (Can be used to
kill X and svgalib programs, see below) This was originally designed
to imitate a Secure Access Key
