How to enable CTRL+ALT+BACKSPACE

[Reindl Harald]

in the newest release the shortcut for restart X11 is disabled
and i hate it because if X11 drives crazy it is really useful
and where i work nobody kills my X11 if he won't killed self

i guess the following config-file does this disable but
the comment says "changes here are useless", so how tell
"system-setup-keyboard" not wanting the last line?

[root at rh:/etc/X11/xorg.conf.d]$ cat 00-system-setup-keyboard.conf
# This file is autogenerated by system-setup-keyboard. Any
# modifications will be lost.

Section "InputClass"
        Identifier      "system-setup-keyboard"
        MatchIsKeyboard "on"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "de"
        Option          "XkbVariant"    "nodeadkeys"
        Option          "XkbOptions"    "terminate:ctrl_alt_bksp,"
EndSection
