    At some point, the environment variable R600_STREAMOUT=1 stopped working and now it is reporting OpenGL 2.1 again instead of 3.0 on r600g.

    The variable to enable GLSL 1.30 still works.

I traced it back to the bug report and patch in https://pokersource.info/show_bug.cgi?id=46766.

    Is there any chance that one last mesa could be released that includes those patches (either b2ace06cbbbb1021e2d7ace12a985c6406821939 or 3d036f3f0aa7360c58d76b3f5114e1cf8c32260c -- i don't understand that last comment at the bottom of the page).

    Thanks so much oibaf!

    Hi, that commit is indeed not included in the latest mesa for natty and oneiric. I stopped supporting them because they need newer dependencies which are not easy to backport from precise (precise/oneiric packages support multiarch, not available in natty, also many precise packages now use debhelper 9, not available in natty/oneiric). I'd suggest to upgrade to precise, remember also that natty will end of life in October.

    I pushed the new nouveau drivers to the precise PPA. radeonsi will have to wait (it requires llvm 3.1).

    Hi oibaf, cool, thanks for letting me know. If there's any chance to leave the natty/oneiric packakges with a version that includes this patch but does not have the dependencies you mentioned, that would be awesome... perhaps some git revision that is slightly more recent than what is in the repo right now.. would be much much appreciated. Perhaps you find the time...
    best,
    Philipp

    Same here on Ubuntu 12.04 (AMD 6570, 32-bit).

    OpenGL renderer string: Gallium 0.4 on AMD TURKS

    OpenGL shading language version string: 1.30
    oibaf, if you need more data from glxinfo tell me, I would like to help.

    There is no magic in my packages and I am not very familiar with r600 driver. If R600_STREAMOUT is broken open a bug on freedesktop, for the OpenGL version it probably require some other thing to enable.

    https://bugs.freedesktop.org/show_bug.cgi?id=47281 is causing problems for me. The fix was supposed to be released on 2012-04-27, and there has been two releases of the ubuntu driver debs since then. But still, I'm getting the same errors.

    Before I go back to the bug saying that the fix doesn't work, is it really included in the latest driver packages?

    The versions on my machine are

    $ dpkg -l|grep radeon
    ii libdrm-radeon1 2.4.34+git1205110954.86451a~gd~p Userspace interface to radeon-specific kernel DRM services -- runtime
    ii xserver-xorg-video-radeon 1:6.14.99+git1205111032.4b9bad~gd~p X.Org X server -- AMD/ATI Radeon display driver

    I always had problems to do with chrome's native client applications. Ultimatly most 3D objects in the game appeared all black. Now that I've updated mesa using your PPA those long time problems have stopped. Thanks oibaf!
