I dislike Ctrl-Alt-Delete, because I sometimes hit them by accident.
Nevertheless Ctrl-Alt-Delete still seems to be needed because it's
more reliable than Ctrl-Alt-F1 and other variants when X hangs.

So I *neither* want Ctrl-Alt-Delete working like today, *nor*
completely disabled.

Two separate propositions follow. No GUI would be needed to edit any
preferences in either case.

1) So I would like Ctrl-Alt-Delete to take me out of X to a GRUB-like
menu asking me something like "Do you want to immediately shut down
the log-in session, thereby losing any unsaved work?". Is that
technically possible?

2)  We could do what SuSE did (or does?): "Pressing Ctrl-Alt-Backspace
on GNOME, KDE, or any other graphical desktop does not terminate the X
server any longer. If you press Ctrl-Alt-Backspace within 2 seconds
again, it terminates the X server. On most hardware you hear a beep
after the first Ctrl-Alt-Backspace press." See
