I'd considered that myself. But being an obstinate bastard with lots of
usabe hardwar laying around begging to be used, I tend to do things the
hard way. It's surprising how much I've learned over the years that way.
Anyway, I've ATI and Nvidia cards with dual capability (1 analog, 1
digital) and I figured that by now both would be supported even in EL
distros. Guessed wrong it seems.
My theory is it's a pure Xorg issue. I'll take the time to wait and see
what happens and then decide how to proceed.
Thank you for taking the time and effort.
