You use either DRI, or Xinerama, but not both. DRI+Xinerama is not supported in XFree86 currently. >I'm still tinkering around.

I've tried em all to no avail. For Radeon hardware, you should be using the stock Red Hat supplied out of the box configuration with no 3rd party anything. With single headed configuration, using only Red Hat supplied components, including the kernel, you will have 3D acceleration by default. If you modify or remove the kernel, build your own kernel, or change anything related to DRI, the kernel, Mesa, or anything else related to 3D, or if you install Nvidia or ATI or any other 3rd party video drivers, then you will end up unable to use DRI as supplied with the distribution unless you reinstall all of the Red Hat supplied XFree86 components. This is because Nvidia and other driver installations blow away Red Hat supplied important X server files when you install their proprietary drivers, and the only way to ever use XFree86 with the drivers it is shipped with properly again, is to reinstall the binary rpm packages again to replace the files that were deleted by the proprietary driver installation. There is only one other reason why you would not get 3D acceleration out of the box on a Radeon card, and that would be if it is PCI. Only Radeon AGP hardware is officially supported. Support for DRI 3D acceleration on PCI hardware is disabled in the driver by default, and requires the ForcePCIMode option to be enabled. That option is very unstable for the majority of users which is why it is disabled by default. If you're using a stock system which hasn't been modified in any way as indicated above, and your video card is AGP, then I've no idea why you're not getting 3D, but it is a unique problem if it doesn't match what I've said above, because I can assure you that 3D very much works out of the box on AGP Radeon hardware, excluding the 9500 and newer cards, and the IGP series. ;o) -- Mike A.
