Grab the ATI Driver Installer it supports Xorg 7.1

Okay, I did that. I have now been fighting with xorg.conf and system-config-display for about an hour and I still have mirror screens and do not know what to do. Here is my xorg.conf (which isn't even changed as I write this, it just doesn't work) and excerpts from the Xorg.0.log where there were errors (EE) or warnings (WW) and I don't understand some of these. Hopefully someone out there will?

xorg.conf:

Don't I need something that has a Screen section with two Display subsections? I can't remember what that was....

Anyway, here are the errors and warnings from my Xorg.0.log (there were no notices or unknowns):

None of these look to me like they are related to the problem - no dual head. What's worse is that s-c-d doesn't seem to understand this either. It shows:

Settings: 800x600, Millions of colors (with only 640x480 as the other res option)

Hardware: Generic Autodetecting Monitor (should be Dell 1707FP) and Unkown Video Card (which is actually correct - this is the fglrx driver).

Dual Head: Use Dual Head, Generic Autodetecting Monitor (see above), Second video card is "ATI Technologies Inc Unknown device 71d2" (which is technically correct but useless), 800x600 (no options), Millions of colors and "Spanning Desktops" which do not appear.

Anyone know what this is/might be and, hopefully, how to fix it?

On top of all that, now only the floating feet and pattern screen savers work. Wonderful.

Please note that these are probably NOT CentOS bugs/problems, I'm just grasping at straws in hopes of finding something here that will fix this.

Thanks.
