Ctrl-Alt-Del is in /etc/inittab:
# Trap CTRL-ALT-DELETE
ca::ctrlaltdel:/sbin/shutdown -t3 -r now
Ctrl-Alt-Backspace is in /etc/X11/xorg.conf:
Section "ServerFlags"
#DontZap # disable <Crtl><Alt><BS> (server abort)
#DontZoom # disable <Crtl><Alt><KP_+>/<KP_-> (resolution switching)
AllowMouseOpenFail # allows the server to start up even if the
mouse doesn't work
But preventing a user that has physical access to the machine from
rebooting it or shutting it down is rather pointless. They can
always pull the plug to do a shutdown. (Unless you have an internal
UPS.) I would rather let them do a controlled shutdown...
