On my Lenovo Ideapad S110 Debian Stretch is just working fine, but HD videos don't run smoothly, at least not in full screen.

i965-va-driver is installed and up to date, vainfo returns

    sudo vainfo
    error: XDG_RUNTIME_DIR not set in the environment.
    libva info: VA-API version 0.39.4
    libva info: va_getDriverName() returns -1
    libva error: va_getDriverName() failed with unknown libva error,driver_name=(null)
    vaInitialize failed with error code -1 (unknown libva error),exit

Maybe anybody can help. Thanks!

  • All HD videos? And are they local files or from streaming? Codecs, etc.? – user252181 Feb 6 '18 at 14:52

Your laptop has a GMA 3150 integrated GPU, which isn’t supported by the i965 VA-API driver. I’m not aware of any way to get it working better; it’s rather under-powered for full-screen HD video... The hardware only supports MPEG-2 acceleration, not H.264 acceleration, which is what you’d typically need for HD video.
