Are you running shutdown(8) in an X session? Besides the video mode
possibly not switching back to tty, an excerpt from Debian's man page
(which uses sysvinit-core):
      I close all my tabs in Firefox and then shut down Firefox.  I usually
      have two terminals still open, and I shut down one of them.  With
      only one terminal open, but X of course still running, I then
      invoke    sudo shutdown -h now   .


> Init can only capture CTRL-ALT-DEL and start shutdown in console mode. If the system is running the X window System, the X server processes all key strokes. Some X11 environments make it possible to capture CTRL-ALT-DEL, but what exactly is done with that event depends on that environment.
     <G>  I know about CTRl-ALT-DEL !  but I was under the impression that
     'shutdown' was a replacement, to be used in an X environment.  Am I
     wrong?

Thanks for your message!  I'm still not quite clear, but as I said originally
it is a question almost completely lacking in significance<G>.

Best wishes,

Alan
