Thanks, I'll try that next time I'm near a projector.

Oops, there must be more to it. When I try 'startx -- :1 on tty2, I
get a log of messages from X, none of them errors, but no X screen on
tty8 (or ???). This is now a bit <OT>, so if you want to respond in a
new thread, that's OK.

      the code as cleverly as possible, you are, by definition, not
      smart enough to debug it.
