    this does not work proper on my notebook: black screen after " sudo restart lightdm"
    vgaswitcheroo was the only way to play my games, AMD Catalyst does not install, VirtualGL is too complicated for me.

    -edit-
    I solved using DRI_PRIME=1

    I apologize for my ignorance but this new function is not described in the guides and forums in Italian.
    DRI_PRIME works fine!

    Default undefined symbol in r600_dri.so

    Hi all,

    After running
    LIBGL_DEBUG=verbose glxinfo
    I can see this error:

    libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/tls/r600_dri.so
    libGL: OpenDriver: trying /usr/lib/x86_64-linux-gnu/dri/r600_dri.so
    libGL: driver does not expose __driDriverGetExtensions_r600(): /usr/lib/x86_64-linux-gnu/dri/r600_dri.so: undefined symbol: __driDriverGetExtensions_r600

    Other information in this debug command I think is all ok:
    http://pastebin.com/3U2jCwSQ

    ppa-purge removes this error but when I reinstall the graphics driver, it appears again.

    My graphics card is a Hd4670 agp, and apparently, the graphics driver works well. At least I have not noticed any problems with it.


    Regards.

    This is expected and it's not an error, it's just that gallium drivers don't support megadrivers.

    I added the patch to the PPA (on both 13.10 and 14.04). Please test.

    Hello oibaf, are you planning to enable openmax in your builds for testing?
    Thanks!

    My card is not compatible and I cannot test, but if someone post a patch for the packages or tell me which built files are needed and where to put them I could add it.

    Ok, it definitely works with
    Code:
    mplayer -noconfig all -vo vdpau:deint=3 -vc ffh264vdpau,ffodivxvdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau
    on interlaced video, and
    Code:
    mplayer -noconfig all -vo vdpau -vc ffh264vdpau,ffodivxvdpau,ffmpeg12vdpau,ffwmv3vdpau,ffvc1vdpau
    works great on progressive, but I'm getting a green screen on xbmc (on progressive and black screen on interlaced). But it's maybe something wrong with my system - I haven't tried it on clean install.
    (Also, there is a warning at xbmc.org by fritsch "Installation of the wsnipex repository which includes all relevant mesa patches in a stable version. Don't use oibaf ppa - it will produce black screens only.")
    Thanks!

    I think that wsnipex PPA only added this patch more than my PPA, so the warning could be ignored. No idea about the green screen, try asking to xbmc people.
