Hi, I'm running Fedora 9 x86_64 with an ATI Radeon 9800 PRO card. It works well. I just bought a second monitor (now I have two Dell 2001FP 1600x1200 LCD displays) so I've been trying to get a large desktop that spans both of them.
Does anyone have an xorg.conf that supports this setup with the xorg radeon driver (Driver "radeon" NOT "fglrx")?
Out of curiosity, why not find the ATI-provided driver for your card, and use the "amdcccle" tool that comes with it. It behaves much like the Windows Display Properties toolbox, it quite nice actually.

I've tried using the ATI driver but cannot get it to work under Fedora 9 (lots of undefined symbols). I've read numerous posts that indicate that the proprietary ATI driver won't work with Fedora 9. Certainly the xorg radeon driver supports what I want to do, I just haven't figured out how to set up my xorg.conf to make it work.
To spur discussion I thought I'd post my xorg.conf. This duplicates the same desktop on both monitors. Let me know if you have any suggestions on things to try!

Well, I read the xorg.conf man page again and continued my Google search. After much trial and error I've figured it out! Essentially the only changes that I needed to make were to add "Screen 0" and "Screen 1" to the Device sections, and Option "Xinerama" "true" to the ServerLayout section. Here is my working xorg.conf:
