      <para>
        The <application>Xorg Intel Driver</application> package contains the
        X.Org Video Driver for Intel integrated video chips including 8xx, 9xx,
        Gxx, Qxx, HD, Iris, and Iris Pro graphics processors.

      <note>
        <para>
          This driver is for Intel integrated GPU, and a development
          version is needed to work properly with the latest hardware.
          This version is now one year old and has some problems. The
          <quote>Kernel Modes Setting (KMS)</quote> driver shipped along
          with Xorg Server is said to give better results.

      <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 may cause problems.  However, the version of the code in the
        version control system listed above has been tested successfully with
        both SNA and UXA capabilities.
      </para>

      <para>
        To work around this problem, as well as enabling support for UXA, it is
        necessary to force UXA to be used by creating a configuration file.  If
        this problem applies to you, create the following file as the
        <systemitem class="username">root</systemitem> user and modify it as
        needed:
      </para>
