      <title>Working around problems with the Intel driver</title>

      <para>
        The SandyBridge New Acceleration (SNA) code is intended to replace the
        old UXA (UMA Acceleration Architecture), but it is a large body of code
        and sometimes causes problems. In particular, when a system is built
        with gcc-5 and kernel headers from linux-4.0, trying to run this driver
        using SNA will cause a segfault on some, or perhaps all, of the
        supported chips if a 4.0 or newer kernel is used (a 3.19.0 kernel, also
        built with gcc-5, worked ok). To work around this, as well as enabling
        support for UXA, it is necessary to force UXA to be used by creating a
        configuration file.
       </para>

      <para>

        the <systemitem class="username">root</systemitem> user:
