Enable killing Xorg with Ctrl+Alt+Backspace about iso HOT 4 CLOSED

We can literally just place this into /usr/local/etc/X11/xorg.conf.d/10-input-keyboard.conf?

Seems to work if /usr/local/etc/X11/xorg.conf.d/ is used exclusively (in my earlier test I also had /etc/X11/xorg.conf.d/ and that was a problem.)

Edge case: if a user is familiar with a dialogue in response to Control-Alt-Delete (GNOME, KDE, Windows) then after no response to that key chord, the next attempt to gain the dialogue might be Control-Alt-Backspace and a sudden death will be unexpected.

That's not enough of a case for me to suggest not enabling killing. Just food for thought.

Narrower edge case: https://forums.linuxmint.com/viewtopic.php?t=263844 someone used Control-Alt-Backspace whilst guessing how to delete a line. I empathise; after years of using shortcuts, I still sometimes make wild guesses in Konsole and other apps. I have only myself to blame for the consequences :-)

You are right. Maybe we should not enable it by default. The Mac also has no equivalent of this that I would know of.

– comparable, but it's obscure, and I can't recall whether the resulting quits of applications are suitably clean.
