Hi

I made a futile attempt at getting 3D acceleration on my HD4870 yesterday by following the guide at http://www.x.org/wiki/radeonBuildHowTo and others.
I was hoping someone with insight would be willing to highlight the steps neccessary to get this working in Ubuntu 9.04?

EDIT: Just found a guide: http://ubuntuforums.org/showthread.php?t=1257453
EDIT2: https://launchpad.net/~xorg-edgers/+archive/radeon now has pre-built packages for jaunty (as well as karmic) that enables 3D on R600/700, it works! :)

Are you trying to set up 3D with KMS or without KMS ? The instructions are very different depending on what you are trying to do.

Your first link includes both KMS and non-KMS operation; second link is non-KMS only.

Suggest you get non-KMS going first.

Oh, I thought KMS was required for proper 3D on R600/700.
3D only is good enough.

3D only is good enough.Nope, KMS just allows for DRI2 and extending the 3D driver further. You likely do not run into the limitations of non-KMS 3D since there's not that many extensions yet that you get in KMS 3D and won't without. I think FBO's are one such thing but I'd find it likely that you rather run into the GLSL limitations to which having KMS doesn't yet have any significance.
