Re: [XFree86] Purchase Advice Needed: Robust DVI support?

The radeon driver code has code to handle two DVI ports however, the
cards are very rare.  I've never tested it.  Also there might be issues
depending on what tmds/lvds controller the vendor uses since the radeon
only has a one integrated controller.  Dual DVI boards require an
external controller to drive the other DVI port.  Depending on the
controller, you might need additional code to handle its set up.

That rules out that then.

I am starting to think a 1 card dual DVI solution might increase my
chances of success here, especially at higher resolutions.

What cards are known to support dual DVI DFP's, with open source
XFree86
drivers???

The ATI FireGL Z1-128 should be able to do dual DVI at 1600x1200, and I
see it listed as supported by the radeon driver in logs from 4.3.99
that
people post, but this message from Karsten Künne in June saying he
couldn't get it working went unanswered:

??

Can anyone confirm that dual DVI DFP's work for them on the Z1 (or
anything else) before I spend $400 ??

MUCH MUCH thanks for your help!!!!
