    <title>Introduction to XScreenSaver</title>

    <para>The <application>XScreenSaver</application> is a modular screen
    saver and locker for the X Window System. It is highly customizable and
    allows the use of any program that can draw on the root window as a
    display mode. The purpose of <application>XScreenSaver</application> is
    to display pretty pictures on your screen when it is not in use, in
    keeping with the philosophy that unattended monitors should always be
    doing something interesting, just like they do in the movies. However,
    <application>XScreenSaver</application> can also be used as a screen
    locker, to prevent others from using your terminal while you are
    away.</para>

    <para>There may be a more recent release available from the
    <application>XScreenSaver</application> home page. You can check
    <ulink url="http://www.jwz.org/xscreensaver/"/> and probably use the
    existing BLFS instructions. Note that versions other than the one shown
    in the download URLs have not been tested in a BLFS environment.</para>

    <title>Installation of XScreenSaver</title>

    <!-- Apparently, this issue is now fixed
    <para><application>XScreenSaver</application> makes some poor choices
    where to put all the files if <application>GNOME</application> is installed.
    To get around this, run the following command and see an optional configure
    switch described later below.</para>

<screen><userinput>sed -i -e "s,@GNOME_DATADIR@,$GNOME_PREFIX/share," driver/Makefile.in</userinput></screen>
    -->

    <para>Install <application>XScreenSaver</application> by running the following
    commands:</para>

    <!-- sed -i 's,\xc3\xb6,oe,' hacks/flow.man -->

<screen><userinput>./configure --prefix=/usr --libexecdir=/usr/lib &amp;&amp;
make</userinput></screen>

    <para>This package does not come with a test suite.</para>

    <para>Now, as the <systemitem class="username">root</systemitem> user:</para>

    <title>Command Explanations</title>

    <!-- <para><command>sed -i 's,\xc3\xb6,oe,' hacks/flow.man</command>: This
    command replaces the UTF-8 encoded character <quote>&ouml;</quote>
    with its ASCII equivalent <quote>oe</quote> in one of the installed
    manual pages. Without this, <application>Man-DB</application> would
    interpret these two bytes as ISO-8859-1, resulting in
    the wrong <quote>&Atilde;&para;</quote> characters.</para> -->

    <para><option>--with-setuid-hacks</option>: This switch allows some
    demos to be installed setuid <systemitem class="username">root</systemitem>
    which is needed in order to ping other hosts.</para>

    <para><option>--enable-locking</option>: This switch provides support for
    locking the display.</para>

    <!-- Not required any longer
    <para><option>-with-configdir=/usr/lib/xscreensaver/config</option>:
    If <application>GNOME</application> is installed, you can use this
    switch to put the configuration files in a single directory rather than
    spreading them all over the disk.</para>
