The Xenocara base X Keyboard
Extension rules file forces the
terminate(ctrl_alt_bksp)
symbol to be added to all
keyboard models. This kills the X11 server when you
press C-M-<backspace>. I have never found this
shortcut to be useful (it is always a better idea to switch to another
virtual console and try to see what locked up the
graphics). backward-kill-sexp
is on the other hand a very
useful Emacs command that fits perfectly
under C-M-<backspace>. You can
remove terminate(ctrl_alt_bksp)
and free up the keyboard
shortcut by doing something similar to:
diff -c /usr/X11R6/share/X11/xkb/rules/base\~ /usr/X11R6/share/X11/xkb/rules/base

Now you can add this to your .emacs:
(global-set-key (kbd "C-M-<backspace>") 'backward-kill-sexp)
