--- Comment #88 from P.Panon ppanon@shaw.ca 2010-02-25 23:29:27 --- Thanks Cùran.
Edward, I'm afraid I have no idea how to detect Gallium renderers or how to enable them for that matter. I think what I'm going to do is submit the patch(es) as updated by Cùran in attachment 26478. At least that gets Direct3D8 support for R300-R500 and Direct3D9 support for R600-R700. That's better than what you would get for the R3/4/500 with fglrx (since those are no longer supported and maintained in recent revs), and provides open source support for the R6/700 series. It also provides a base for somebody to add Gallium support/detection later so it would be good to get that included into the main trunk so that we don't need to get Cùran to keep on refreshing the patch.
Either someone (else, since I don't have an R3/4/500) can add a new patch in this bug or open a new bug for adding Gallium detection and support.
