[ltp] Independent dual monitors

[Paul Kaplan]

I have two monitors on a T40 237375U.  I can enable/disable Xinerama to make a 
single virtual desktop or two indpendent Desktops.  There were two threads on 
this list in the fall of '03 about this issue.  Weidner's file worked fine 
for me for but I found a better one that let X autodetect whether the monitor 
was there and set the resolution accordingly.  I will forward next week from 
the box that it's on.
