Since the switch to upstart that's not the place to define what happens.

In addition to what upstart does, on a gnome desktop (I don't know if
this is really an xorg setting) the logout function is bound to c-a-del.

Try the gnome setting. System -> Preferences -> Keyboard Shortcuts

There is also a security setting to not allow people to reboot or shutdown
the system. I think in F11 there was still a graphical interface for doing
that. (It seems to have been dropped at some point.) If you disable the
authorization, people can try to do a reboot but it won't happen.
