I just purchased an emachines laptop with an amd64 and an ati radeon 9600 which is now running FreeBSD 5.3-BETA4 beautifully. I need to be able to run OpenGL programs using, among others, the ARB_vertex_program, ARB_fragment_program, and ARB_occlusion_query extensions. These are all part of OpenGL 1.5, which is implemented by the current version of Mesa, Mesa-6.2. Xorg, as shipped with FreeBSD uses Mesa-5.1 as the renderer, so I upgraded from source to Xorg 6.8.1, which is current stable. This uses Mesa-6.1, which *should* give me the functionality I need--but it doesn't. glxinfo tells me my renderer version is OpenGL '1.2 (1.5 Mesa 6.1)'. So I manually replaced the Mesa subtree in Xorg with Mesa-6.2. 6.2 is primarily a bugfix upgrade, but I hoped. I also went through the Mesa source and made certain that all conditionally compiled code that involves the extensions I need are built, and then rebuilt Xorg. Still no dice. Version string is '1.2 (1.5 Mesa 6.2)', and the extension I need are not being exported. I'm not certain that this is actually a FreeBSD question, but it touches on three different systems, so I thought I would try here first. Does anyone have any experience with programmable graphics under FreeBSD. I realize, of course, that the drivers aren't there to really support my card--I could care less if I get acceleration! Mesa exports the functionality in software, and I need to be able to use it. Any suggestions? Jeremy -- Jeremy W.
