Doesn't work, at least, not reliably. Once, I pressed AltGr+SysRq, let
them go and pressed s and got a proper response. Once. Quite possibly
because it didn't need it again. However, I just went back to that
console and now it's working. Go know. The important thing is, I now
know that it has to be the right Alt, not the left, and to try several
times if it doesn't respond the first time. Thanx. If and when I get
another lockup, I'll try it, starting, of course, with r to get proper
control of the keyboard.
