ok, thanks for that. the issue, with using a single dual head display
rather than using multi-seat is that power management will turn on
both screens if one screen is in use. I would rather have only the
screens being used being switched on via powermanagement.

So, I guess I go back to asking how I setup multi-seat.. I have played
with it all day, looking at using kdm and multi-seat display manager
(mdm, it doesnt mention anything after ubuntu 8.04) and I cant get
either to work with 10.10 on my laptop (although I would of course be
looking to implement on 10.04LTS on the server.

(btw; the idea is to use a single remote and "it just work" for the users.
