[plug] configuring Xorg so I can use a digital projector.

[Sol Hanna]

Hi all,

I have a Dell Inspiron 6400 running (Ed)Ubuntu Edgy Eft and I have an
Epson EMP-TW20 digital projector. Both are quite new and working. But
not with each other. :(  

I've been searching the net (esp. ubuntuforumsorg) for some idea of how
to configure Xorg to get video output to the projector. I would also
like to use the projector at school, and so far as I'm aware, this
should not be a problem provided that the projectors have the same
default resolution (which they do == 800x600px). 

My "Screen Resolution" chooser in GNOME gives me a choice of 1280x800
and 1024x768. I've installed a package called i810switch based on the
advice from this post:

+projector

I'm sure I need to edit xorg.conf, but not sure how. Does anyone have
any idea?

thankyou; sol

PS: Below is some of my xorg.conf
