    thanks everyone! I got compositing working in kde, and nexuiz sorta works

    OpenGL vendor string: X.Org R300 Project
    OpenGL renderer string: Gallium 0.4 on R520
    OpenGL version string: 2.1 Mesa 7.8-devel
    OpenGL shading language version string: 1.20

      Sounds like great progress!

      Hopefully the r600g picks up steam soon.

        Unfortunately I am still unable to use effects with kwin and gallium
        on R300. I am using kde 4.4. Anyone has any insight about what might be wrong?

          Your gallium is reporting as 0.3... do a git pull to update to the latest mesa

            i got it to work up to here
            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

                  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.

                        that explain it XD

                          Just my 2 cents:

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

                            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.
                              (damn 1 minute edit limit)

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