I wish I had a digital camera, or that you lived in DC.  I'd invite you 
over for pizza, beer, and a debugging session. :)

I've traded emails with a number of dual-head Radeon users and have 
answered quite a few pleas for help based on my messages in the 
archives.  I've yet to speak to anyone who has a working dual-head 
Radeon set up in RH9/XF86 4.3.0.

If you're out there, don't be shy!  Post your config file!

Ok.  I totally understand the motivation for feeling like your hands 
are tied without a reproducible case.  Let me ask you this: do you have 
a dual-head Radeon 7500 (I'd settle for any Radeon model) for which 
Xinerama works for you in XFree86 4.3.0?  If so, I know there are more 
than a few people who wouldn't mind if you posted the XF86Config file 
for that system <wink>.

My XF86Config file isn't generated by the config tool.  It's derived 
from my XF86Config-4 file which worked just fine in both Xinerama and 
non-Xinerama dual-head configuration on XF4.2/RH7.3.  I include it 
again below.

I'm totally willing to believe it's a misconfiguration on my part.  But 
I've stared at this file countless times, tried countless variations, 
and have had no luck.  Tell me what to try and I will try it.  I'd 
gladly trade public humiliation in a perpetual archive for a working 
Xinerama set up. :)

I would love this.

Tell me what I can do to produce such a test case.  Seems like it would 
be difficult without a picture or movie of my desktop.  A screen 
capture is useless.

Anyway, just so the information's convenient, I'll describe once again 
my hardware set up:

- Single Radeon 7500 PCI card with a VGA and a DVI port in a Dell 
Optiplex box
- Two Dell E171FP analog flat panel monitors
- One panel plugged directly into the 7500's VGA port
- One panel plugged into the DVI port with an ATI supplied DVI->VGA 
converter

I'm running RH9, XFree86-*4.3.0-10.rpm just grabbed from rawhide not 30 
minutes ago.

Symptom: mirroring on both monitors which cannot be turned off.  No 
multiple screens, no Xinerama.  Do you need any other information?  A 
dump of XFree86.0.log?
