    <para>
      <application>Weston</application> is the reference implementation of
      a <application>Wayland</application> compositor, and a useful
      compositor in its own right. It has various backends that lets it
      run on Linux kernel modesetting and evdev input as well as under X11.
      <application>Weston</application> also ships with a few example clients,
      from simple clients that demonstrate certain aspects of the protocol
      to more complete clients and a simplistic toolkit.

    <title>Using Weston</title>

    <para>
      To start <application>Weston</application> as an X11 client,
      from an X terminal, run the following command:
    </para>

<screen><userinput>weston</userinput></screen>

    <para>
      To run it as a DRM compositor, from a TTY, while logged
      in as a normal user, run the following command:
    </para>

<screen><userinput>weston-launch</userinput></screen>

    <para>
      Note that <command>weston-launch</command> is a wrapper for
      <command>weston</command>. If you need to pass a parameter
      to <command>weston</command> while using
      <command>weston-launch</command>, use the following syntax:
    </para>

<screen><userinput>weston-launch -- --backend=fbdev-backend.so</userinput></screen>

    <para>
      Note the -- between the <command>weston-launch</command> and
      the <command>weston</command> parameter
      <parameter>--backend=fbdev-backend.so</parameter>. For list
      of parameters that you can pass to <command>weston</command>,
      consult the <command>weston(1)</command> manual page.
    </para>

    <para>
      To terminate <application>Weston</application> when running
      as a DRM compositor, use the CTRL+ALT+Backspace
      combination on your keyboard.
    </para>

    <para>
      Note that the default backend, DRM, will only run if a
      KMS driver is present on the system. It will not run in
      a virtual machine such as VBox or Qemu and on NVidia or
      AMD hardware with proprietary drivers. On these setups
      it would be possible to use the FBDEV backend by running
      the command described above.
    </para>

    <para>
      Also note that X11 backend requires working EGL stack.
      If you are running hardware that has no 3D support or
      no EGL stack, you can't run accelerated applications
      inside <application>Weston</application>. Latest
      proprietary NVidia driver has the necessary EGL
      stack needed to run <application>Weston</application>
      as an X11 client, but it is not officially supported.
