I thought this might be of interest. I have two screens defined, one is
a 1280x1024 projector, the other a TV. This is a simple xorg.conf file
that I wrote after a lot of research and it works just as I want. I can
put mythtv on either or both screens.
The way I normally use it is to restart X and if the projector is turned
on, that is where myth shows up. If the projector is off, myth shows up
on the TV. However, the other night I forgot to restart X and I turned
on the Tv and there was the blue screen. I chose to start another
instance of mythtv on the TV rather than restart X and that worked as
well. Now, if I turn on the projector, all I have to do is move the
mouse over to that screen to give it focus and I am good to go.
You might want to let the auto configure program run and see if it
prints out some monitor specific information like refrech rates and edit
this file before trying it. If you don't have a TV, you can edit those
three sections out.
In any event, you will need the projector on when you start X for this
to work. There are ways around that, but that is another discussion.
Hope this helps,
Allen
