In this particular instance, we *know* that my laptop is capable 
of dual-display with the external monitor as an extension of the 
built-in one, because that arrangement works perfectly under 
Windows. The laptop Daniel is using is (I believe) one of my 
older ones, and I'm fairly sure (though not 100%, as my memory is 
notoriously poor on this sort of detail) that I used it 
previously in the same way under Windows. So it's only a problem 
of getting it to work under Ubuntu.

Cheers, Jean
