If you are running 10, you want WITH_NEW_XORG, the fairly current Xorg code. It requires the option because X.org dropped support for a lot of older GPUs. You can try WITH_NEW_XORG and see how well it works with your AMD system. 10 also brings KMS support for AMD GPUs. I have none, so I can't say how well it works. I forgot that the kernel is now always built to support KMS, so it's only the X ports that require a re-build. --=20 R. Kevin Oberman, Network Engineer E-mail: rkoberman@gmail.com
