Got it here. Now to attach it ...

Honestly, your on a linux distribution with a version of Xorg that is over 5 years old. The chances of getting useful support with such an old version of Xorg is small. All I can really say is that the driver does not support xrandr 1.2, so you'll have to use MergedFB. I suggest checking the 'radeon' man page for information about MergedFB. But, again, bear in mind that the driver has changed a lot in 5 years. It's quite possible that the error about not detecting a secondary monitor is a bug in the driver back then, and has been fixed in newer versions.

Is there any reason why you're returning to Linux by installing such an ancient version?

I'm trying to simulate what a customer is doing; they run Red Hat linux, but will be paying for current versions. 5.7 is the latest I could download and burn to CD's as a 30-day trial. What do you mean by Xorg and MergedFB? Maybe I just have to bite the bullet and buy the current version. I'll try for a driver update for the Radeon video card first.

Thanks, Dick

Xorg is the X server. MergedFB is a feature of the radeon driver that extends one screen across multiple monitors. It's deprecated and no longer supported, having been replaced by xrandr 1.2.
