Thanks Greg. After your first reply I did actually try the Nvidia linux support forum, and got
a reply from someone from Nvidia saying that the Xinerama specs say that the GLX will only report capabilities
available on all displays. I am going to get a dual-link capable display-port adapter for the Quadro
so I can run it in TwinView instead of Xinerama. The Nvidia guy was reasonably certain that that would
work where Xinerama wouldn't. Worth a try... I will report the results here after I give it
a try for posterity.
