The Xorg man page says "[Zapping] can be enabled with the -retro command line or by setting the DontZap xorg.conf(5) file option to a FALSE value." However, if I pass -retro, I get the ordinary background pattern, yet pressing ctrl+alt+backspace does not kill the server. Furthermore, adding Option "DontZap" "False" to the ServerFlags section in my xorg.conf does not enable zapping either, with or without the -retro option. This appears to be the case with all server versions since (at least) 1.6.3.

Thanks, that did the trick. It appears that adding Option "XkbOptions" "terminate:ctrl_alt_bksp" to xorg.conf is the only thing necessary to enable zapping -- neither the -retro or the DontZap option are required. So I guess this is a documentation bug, then.

The documentation has been updated as of git commit bbffb85461.. on Sep 10 11:55:34 to mention the need to map terminate to Ctrl+Alt+Backspace.
Great, thanks. Just a note, though, the man page now reads roughly like the following: The follwing is commonly part of the default keymap ... ctrl+alt+backspace immediately kills the server ... note that ctrl+alt+backspace is not part of the default keymap. which is a little awkward.
