    <para>
      <application>Xfce4 Session</application> is a session manager for
      <application>Xfce</application>. Its task is to save the state of your
      desktop (opened applications and their location) and restore it during a
      next startup. You can create several different sessions and choose one of
      them on startup.

    <para>
      When building an <application>Xfce4</application> package, some
      configuration files are installed in <filename class="directory">
      /usr/share/applications</filename>, <filename class="directory">
      /usr/share/icons</filename>, and <filename class="directory">
      /usr/share/mime</filename>. In order to use those files in your
      <application>Xfce4</application> session, you need to update various
      databases. Do that by running, as the <systemitem class="username">
      root</systemitem> user (you need to have the recommended dependencies

    <title>Starting Xfce4</title>

    <para revision="sysv">
      You can start <application>Xfce4</application> from runlevel 3, using
      <xref linkend="xinit"/>, or from runlevel 5, using a Display Manager,
      such as <xref linkend="lightdm"/>.
    </para>

    <para revision="systemd">
      You can start <application>Xfce4</application> from a TTY using

      <xref linkend="lightdm"/>.
    </para>

    <para>
      To start <application>Xfce4</application> using <xref linkend="xinit"/>,
      run the following commands:

<screen><userinput>cat &gt; ~/.xinitrc &lt;&lt; "EOF"

EOF

startx</userinput></screen>

    <para>
      The X session starts on the first unused virtual terminal, normally vt7.
      You can switch to another vt<emphasis>n</emphasis> simultaneously
      pressing the keys Ctrl-Alt-F<emphasis>n</emphasis>
      (<emphasis>n</emphasis>=1, 2, ...).  To switch back to the X session,
      normally started at vt7, use Ctrl-Alt-F7. The vt where the command
      <command>startx</command> was executed will display many messages,
      including X starting messages, applications automatically started with
      the session, and eventually, some warning and error messages. You may
      prefer to redirect those messages to a log file, which not only will keep
      the initial vt uncluttered, but can also be used for debugging purposes. This
      can be done starting X with:

    <screen><userinput>startx &amp;&gt; ~/.x-session-errors</userinput></screen>

    <note revision="sysv">
      <para>
        You may wish to drop dbus-launch, e.g., just using
        startxfce4 in ~/.xinitrc. However some capabilities such as mounting or
        umounting file systems from a file manager will not be possible, or the
        reboot option will be absent or inoperative, among other problems.
      </para>
    </note>

    <para>
      When shutting down or rebooting, the shutdown messages appear on the vt
      where X was running. If you wish to see those messages, simultaneously
      press keys Alt-F7 (assuming that X was running on vt7).
