Restore ctrl-alt-backspace to exit from X

It used to work in the old pups. /etc/X11/xorg.conf had this:

Section "ServerFlags"
# Enables mode switching with xrandr
# There is a report that this can cause Xorg not to work on some
# video hardware, so default is commented-out...
# but i want to use it in xorgwizard so leave on...
    Option "RandR" "on"
# Xorg 7.4, Ubuntu Jaunty, CTRL-ALT-BACKSPACE is disabled by default...
    Option "DontZap" "false"
EndSection

However, many years ago, Xorg stopped recognising "DontZap", as explained here:

Forum member Caramel discovered this, and posted the fix here:

I have implemented this. /etc/X11/xorg.conf.d/10-evdev-puppy.conf now has this:

Section "InputClass"
        Identifier "evdev keyboard catchall"
        MatchIsKeyboard "on"
        MatchDevicePath "/dev/input/event*"
        Driver "evdev"
        Option      "XkbRules" "xorg"
        Option      "XkbModel" "pc102" #xkbmodel0
        Option      "XkbLayout" "us" #xkeymap0
        #Option      "XkbVariant" "" #xkbvariant0
        Option "XkbOptions" "terminate:ctrl_alt_bksp"
EndSection

Mystery solved!
