Thanks, Antony. I put in i810switch because several people 
(including James Gray) had said I needed it... also as a way of 
testing that the second monitor was working with Ubuntu.

Most of the time I will want to use the second monitor as an 
extension. Sometimes (like when giving demonstrations) I will 
want to use a second monitor as a clone. So it would be good to 
be able to have the ability to do either.

My primary interest is in having the monitor extend (not clone), 
so I am willing to do whatever is necessary to get that working. 
A "minimalist" solution sounds good to me.

Should I just take the "i810rotate" line out of the startup file 
so it doesn't do anything on bootup, or should I do something else?

Thanks for your help.
