    OpenGL vendor string: X.Org R300 Project
    OpenGL renderer string: Gallium 0.4 on RS690
    OpenGL version string: 2.1 Mesa 7.8-devel
    OpenGL shading language version string: 1.20

    but if i tri to run glxgears for example i got this

    glxgears[5714]: segfault at 45c ip 00007fdc86543525 sp 00007ffff91cb060 error 4 in radeong_dri.so[7fdc8651d000+22f000]

    what can i do?
    Producing a useful back-trace via gdb would be the most important thing. Looks like you're using a 64 bit system, I don't know if any of the developers is testing this on 64 bit (I'm certainly not). So it might be a rather simple thing that you can fix yourself and provide a patch for.

      yep 64 bits FTW!!

      this is all i could get from gdb

      Program received signal SIGSEGV, Segmentation fault.

        I'm using 64 bit so it is probably RS690-specific

          I update the code daily. But unfortunately no luck.

            IIRC, gallium is currently broken on cards without vertex shaders like your RS690.

                Just my 2 cents:

                radeon driver works for me, but its performance isn't as half as with classic driver.


                OpenGL vendor string: DRI R300 Project
                OpenGL renderer string: Mesa DRI R300 (RV350 4152) 20090101 x86/MMX/SSE2 TCL DRI2

                glxgears
                7116 frames in 5.0 seconds = 1423.112 FPS
                7295 frames in 5.0 seconds = 1458.875 FPS
                7301 frames in 5.0 seconds = 1460.139 FPS

                  glxgears is not a benchmark... And no, better/faster OpenGL implementations needn't neccessarily be faster in glxgears as well. Try some real 3d application as a benchmark.

                    Well, that's not to say the G3D driver should be faster for other applications - but might. It wouldn't surprise me if it isn't though since the driver barely is optimized, yet.

                      Tried, and it's pretty much the same: with radeong I get half of the FPS I get with classic driver, playing Counter Strike.
