Yep, I'm a "greenie" at heart. *Nothing* goes to the dump until it is
properly aged or stinks to bad from the mold that grew on it in a deep,
dark, moist storage location.  (:-P

I do have an Nvidia and another ATI with the analog and DVI connectors
though. So I can move that direction if needed.

Uh... you missed the start of the thread I guess. That was the point of

system-config-display, manual massage of xorg.conf after initial

As mentioned, did that to start. Since the two monitors are identical at
this point, didn't have to dink with any of that to start. I did tweak
them later to suit my preferences.
