The screen is connected through an Iogear switch so the screen works
with two Linux boxes.  I assume that this is a digital connection,
although I don't really know.  Everything is fine with the other box
as well as the old box I am replacing.

I tried:  xrandx --verbose -s 1440x900

I get:  "Size 1440x900 is not found in available modes"

I am considering taking the video card from the old box and putting
it in the new one, and ignoring the original card in the new box.
Might this work?

Mike.
