    Have I forgot a step?
    In /home/$yourname/ search for .pam_environment, if there isn't create it, then edit the file and add these two lines:
    Code:
    R600_GLSL130=1
    R600_STREAMOUT=1
    If it's a multi-user system, do it for every user. The result is the same and, if there are problems, you can just remove a file in your home.

    me too! it works like a charm!

    I also added PCIE_GEN2 = 1 and VBLANK_MODE = 0

    I generated My xorg.conf by Xorg -configure and I have added swapbufferswait "FALSE"

    No major improvements of performance in games, for example regnum online, but glxgears reachs incredible numbers now

    Hello!
    First of all, thanks for this incredible PPA, it really helps a lot
    xorg-edgers was some really weird bugs with my graphic card, like, from times to times my monitor looked like an old TV...

    Anyway, i installed your PPA because i saw you added support for s3tc texture compression, and it's something i needed.
    I recently got the new Humble Bundle, and Anomely: Warzone Earth, the game i wanted from this bundle, gave me this error:

    Code:
    GLX_EXT_swap_control not supported, unable to set vertical sync.
    Extension EXT_texture_compression_s3tc not supported. Shutting down the game.
    That time i was still using xorg-edgers. Found your ppa, did a ubuntu fresh install, added your PPA, installed the game... and well, still can't play.
    Now the game don't give me that error, but just finish my Unity session and send me back to LightDM.

    I'm also having problems with .rmvb files on VLC 2.0-rc1. Dunno if the problem is from VLC or your PPA, since i did not tested without de PPA, but .rmvb files get really slow, while a bluray rip .mp4 plays normal.

    Here are my system specs:
    Ubuntu 11.10 64 bits
    Intel i5 2400M with a HD 3000 Sandy Bridge graphic card

    When i run glxinfo | grep OpenGL i get the following:

    Code:
    Mesa: Initializing x86-64 optimizations
    OpenGL vendor string: Tungsten Graphics, Inc
    OpenGL renderer string: Mesa DRI Intel(R) Sandybridge Mobile 
    OpenGL version string: 3.0 Mesa 8.0-devel (git-84a1273 oneiric-oibaf-ppa)
    OpenGL shading language version string: 1.30
    OpenGL extensions:
    Any idea about how i can play the game?

    Also, is intel-sna PPA (https://launchpad.net/~sarvatt/+archive/intel-sna) supported? Does it works with your PPA?

    Again, thanks for the awesome PPA

    Just a complement to the question i made above.

    Talked with the Intel-SNA PPA guy and here is what he told me:

    Ah I'm sorry, it's totally not ok to use it after looking at his PPA.
    We have a different xserver video ABI in xorg-edgers, it won't work
    without rebuilding it against his ppa packages I'm afraid It is
    trivial to rebuild it though if you want to, just dget -u -x the .dsc
    from my sna PPA, cd to the xserver-xorg-video-intel-whatever directory
    and debuild -uc -us -b, it'll tell you what packages you need to
    install to build it.
    I'm not confortable with building those stuffs, never did on my life to be honest. I guess the closest i got from building something on Ubuntu was compile a kernel.
    But i will give it a try this weekend and see how it goes

    Just thought you guys would like to have the info ^^

    You should not use "export" in configuration file.
    Configuration files are not scripts.
    Put "VARIABLE=value" there.

    This is same for Q. and everyone.

    ~/.pam_environiment is only for systems with PAM installed (Ubuntu, obviously) and it is only for assigning user customized vars.
    Meaning, it will not be global. /etc/environiment is for global definitions.

    will you update this ppa soon for precise?

  8. #248

    Default

    I already pushed mesa + libtxc for precise. My mesa packages however are currently superseded by official Ubuntu ones (based on 8.0 branch rather than on master one). It make sense to use that now to spot possible bugs before the final mesa release. Once 8.0 is released I'll push again packages from master calling them 8.1. I'll push X driver later on.

    those people that want to spot bugs shouldnt use your ppa then.

    pretty pls push your ppa for precise now. id like to use that fancy opengl3 stuff, etc...

    i dont want to go back to 11.10.

    What do you expect on master vs. 8.0 branch? Intel is already OpenGL 3.0 on 8.0 and r600 is still not OpenGL 3.0 on master, unless you force it. Anyway is there something useful needing OpenGL 3.0?
