Hello, I was just at the r300 sourceforge page trying to figure out my alternatives to the ati-fglrx propritary package. I am using a modified kernel - the CCRMA 2.6.14-0.10.rrt.rhfc4.ccrma PREEMPT kernel - and the ati-fglrx module will no longer build with the spinlock changes that have been implemented to make the machine more realtime capable. What are my options for getting my machine to utilize this graphics card to help my system become more responsive? How do I get the latest linux drivers for my card? Thank you for your help, and for working on opensource in the first place! -thewade |

How do I get the latest linux > drivers for my card? xorg 6.9 already has (2d and 3d) drivers for r300. If you want newer drivers, you could try Mesa cvs (I believe you also need drm cvs in that case). The r300 sourceforge project has been fully integrated into Mesa cvs. As an alternative, you could possibly try to make ati's fglrx driver compile again, the kernel changes usually only break the small open-source part of it. You'd need to ask the ccrma (whatever that is) people/forums, there might even be patches floating around. Roland |

I asked this on the planetCCRMA list but because the ati-fglrx project is propritary I have gotten minimal response. Which I understand. I guess that nvidia cards are the best supported Linux graphics cards? Thanks for the help! -thewade |

As said, 6.9, or 7.0 (which is functionally identical). > Are there an special x.org Radeon configuration options? See man radeon. Color tiling makes a lot of performance difference, if it works for you. > Is there some widely used Linux 3D and 2D benchmarking tool? Apps actually used are useful benchmarks. Quake3, ut2k4, doom3 all have demos with a easily used benchmark mode. For the more professional work, specviewperf might be useful (performance highly vertex bound). As long as you don't use glxgears... x11perf is the oldtimer for 2d benchmarks, but probably careful examination of the results is needed, quite a few tests of it are meaningless nowadays as noone actually uses these functions today. There are other benchmarks for evaluating composite performance and such, but I'm not up to date on these. >> As an alternative, you could possibly try to make ati's fglrx >> driver compile again, the kernel changes usually only break the >> small open-source part of it.

For binary drivers, probably yes (it wouldn't surprise me though if their driver wouldn't compile neither with unofficial kernel versions). Their exists however no open-source 3d driver for nvidia graphic chips at all (for xorg, that is, there exists one at least for old ones (up to and including GeForce2 chips) for beos). Roland |
