Sorry for posting the previous. Gmail sorted the mails by thread, so I
read this before the other discussion. Instead, the login screen could
instruct you to press Alt+SysRQ+K or any other key captured by the
kernel.

By the way, Alt+SysRQ+K doesn't do anything on my laptop?
Alt+SysRQ+REISUB does work, so what's that about? Could it have
something to do with that my VTs don't exist? (proprietary NVIDIA
driver issue)
