As far as I remember, Fedora has it compiled in, but the standard is

Yes. I did that when I set it up, and after rebooting to start the new
kernel, I made sure that it was set correctly. It is. Now, by
"pressing and holding down AltGr+Prt(SysRq)" do you mean that I hold
those two keys down, let go and then press the other key? It's not
clear, because I'm not sure exactly what I did to get a proper response.
And, what does "AltGr" mean? Is it either Alt key, the left one or
the right one? Again, I managed to make it respond a few times, but I'm
not really sure what I did. Much better to practice now, and learn how
to make it work reliably rather than wait for an emergency and hope I
can get it to respond!
