I need to start running a dual head on one of my machines. Eventual target is CentOS 5.x. Decided to test first on my 4.6

Briefly, kudzu did the right thing when I installed the second card. System-config-display also behaved correctly. X start ok, but will only use one head at a time. <snip>
Q1: Anyone have a two video card CentOS 4.6 setup working?
Q2: Is it working in CentOS 5?
Q3: Anyone see something I'm doing wrong? Suggestions?
TIA,

Does this help you out? I haven't had occasion to play with dual head yet.
A quick google also turned this up, but it is not directly related to CentOS, I run an nvidia card and can't speak to how well this would work for you.

Good reading, even though I am not doing dual-head at the moment.
First thing that popped in my head upon reading the initial request was check Matrox.. they've always been on the high-end and I knew their graphics cards were well supported in Linux. Shop eBay and see Matrox' site (http://www.matrox.com/graphics/en/support/drivers/) to compare whether the card has a Linux driver. Many of their models are dual-head on one card.
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.
Cheers, Glenn
