      </para>

      <para>
        In the instructions below, all the available drivers are built.  That
        will almost always work.  However, it is not efficient.  Depending on
        your video hardware, you probably need only specific drivers.
      </para>

      <para>
        The first thing you need to know is which type of video device you
        have.  In some cases it is built into the CPU.  In others it is a
        separate PCI card.  In either case you can tell what video hardware you
        have by installing <xref linkend='pciutils'/> and running:
      </para>

      <screen role='nodump'><userinput>lspci | grep VGA</userinput></screen>

      <para>
        The video device is most likely one of three families: AMD, Intel, or
        Nvidia.  See the Command Explanations for
        <parameter>-D gallium-drivers=auto</parameter> below to
        see what options are available for your specific video hardware (or
        emulated video hardware).  You should probably add the swrast option as
        a backup driver.
      </para>

      <para>
        For 'platforms' you can select x11 and/or wayland.  Note that in BLFS
        currently only Gnome and KDE can use wayland.  If you are not going to 
        use one of those desktop environments then you probably only want x11.
      </para>

      <para>
        For 'vulkan-drivers' you may want to limit the selection to your
        current hardware.  These drivers are used by some specific applications.
        
        For example, ffmpeg (including ffplay) will use Vulkan instead of
        OpenGL for rendering video on the GPU. If you do not want to do this
        you may or may not want to install them.
        See the Command Explanations for
        <parameter>-D vulkan-drivers=auto</parameter> below to
        see what options are available for your specific video hardware (or
        emulated video hardware).  You should probably add the swrast option
        as a backup driver unless you don't need Vulkan at all.
