Hi golinux,

Alt-reisub/o seems to be working for me, and I didn't do anything to enable
it.

If you look in /etc/sysctl.d there is a file README.sysctl which basically
says you can create and name config files in this directory just about
anything. Here are the notes which I've kept for Ubuntu from back in the
pre-systemd days:

-----------------

open sysctl.d using 'open as root'
edit 10-magic-sysrq.conf
comment out the ridiculous default, replace it with the code to allow all
sensible 'magic' keys
("1 - enable all functions of sysrq". You might like to give it extra
thought. I don't.)
CODE: SELECT ALL
#kernel.sysrq = 127
kernel.sysrq = 1

save it, and remember to come out of elevated priviledges.
