    Even with llvm 3.4 it should still advertise OpenGL 3.1, if you're stuck at 2.1 it's most likely because of missing floating point textures. Are you passing --enable-texture-float to configure when building mesa?

    Weird... I tried to install LLVM 3.5, but it is not taken into account by mesa. I suppose it has to be configured at build time. By the way, I do not compile the packages myself, so if texture float is not enable in Debian packages it will be a problem... I'be just bought Europa Universalis, and I hoped to play under Linux. But for now, the display is so laggy I can't event try.



    Here is the output of glxinfo | grep OpenGL :
    OpenGL vendor string: VMware, Inc.
    OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.4, 128 bits)
    OpenGL version string: 2.1 Mesa 10.1.0-rc2
    OpenGL shading language version string: 1.30
    OpenGL extensions:

    That's definitely very wrong. You are getting software rendering, because the radeon driver isn't even loading.

    That's true ! I did not even notice it was written renderer = llvmpipe... I need to check my logs to find why

    BTW, you should rebuild Mesa after installing LLVM. Otherwise, bad things may happen.

    The non-init of the driver was coming from the non presence of glamor in current Debian Jessie...

    I added Kanotix repository and now everything works ! well, at least opengl 3.1.

    Thx a lot
