+    <title>Creating an X11R6 Compatibility Symlink</title>
+
+    <para>Until recently (relatively speaking) almost every
+    <application>X Window</application> installation you performed or came
+    across was installed in the
+    <filename class='directory'>/usr/X11R6</filename> directory. That was the
+    standard for years. Developers picked up on this and wrote their package
+    installation scripts looking for <application>X</application> in the
+    standard location. Things have changed and the trend is to now install
+    <application>X</application> in
+    <filename class='directory'>/usr</filename>. Some people want to install
+    it in a custom location.</para>
+
+    <para>Many package developers have not caught up to the change and their
+    packages are still trying to find <application>X</application> in
+    <filename class='directory'>/usr/X11R6</filename> and subsequently fail
+    when you try to build the package. Though for most packages it is not
+    difficult to 'hack' the installation script to fix the problem, that is not
+    the long term solution to the problem. Upstream developers need to modernize
+    their installation scripts and eliminate the problem altogether.</para>
+
+    <para>Until then, you can create a symbolic link to satisfy the
+    <filename class='directory'>/usr/X11R6</filename> requirement so that you
+    won't be inconvenienced with a package build failure due to this known
+    issue. If you wish to create the symlink, issue the following command as
+    the <systemitem class="username">root</systemitem> user (ensure you modify
+    <replaceable><$XORG_PREFIX></replaceable> appropriately):</para>
+
+<screen role="root"><userinput>ln -vsf <replaceable><$XORG_PREFIX></replaceable> /usr/X11R6</userinput></screen>

+      </indexterm>
+
+      <para>Xft provides antialiased font rendering through
+      <application>Freetype</application>, and fonts are controlled from the
+      client side using <application>Fontconfig</application>.  The default
+      search path is <filename class="directory">/usr/share/fonts</filename>
+      and <filename class="directory">~/.fonts</filename>.
+      <application>Fontconfig</application> searches directories in its
+      path recursively and maintains a cache of the font characteristics in
+      <filename>fonts.cache-1</filename> files in each directory.  If the cache
+      appears to be out of date, it is ignored, and information is (slowly)
+      fetched from the fonts themselves.  This cache
+      can be regenerated using the <command>fc-cache</command> command at any
+      time. You can see the list of fonts known by
+      <application>Fontconfig</application> by running the command
+      <command>fc-list</command>.</para>
+
+      <para>If you've installed <application>Xorg</application> in any prefix
+      other than <filename class="directory">/usr</filename>, the
+      <application>X</application> fonts were not installed in a
+      location known to <application>Fontconfig</application>. This prevents
+      <application>Fontconfig</application> from using the poorly rendered
+      Type 1 fonts or the non-scalable bitmapped fonts. Symlinks were created
+      from the <filename class="directory">OTF</filename> and <filename
+      class="directory">TTF</filename> <application>X</application> font
+      directories to <filename
+      class="directory">/usr/share/fonts/X11-{OTF,TTF}</filename>. This allows
+      <application>Fontconfig</application> to use the OpenType and TrueType
+      fonts provided by <application>X</application> (which are scalable and
+      of higher quality).</para>
+
+      <para><application>Fontconfig</application> uses names such as
+      "Monospace 12" to define fonts.  Applications generally use generic font
+      names such as "Monospace", "Sans" and "Serif".
+      <application>Fontconfig</application> resolves these names to a font that
+      has all characters that cover the orthography of the language indicated
+      by the locale settings.  Knowledge of these font names is included in
+      <filename>/etc/fonts/fonts.conf</filename>. Fonts that are not listed
+      in this file are still usable by <application>Fontconfig</application>,
+      but they will not be accessible by the generic family names.</para>
+
+      <para>Standard scalable fonts that come with <application>X</application>
+      provide very poor Unicode coverage.  You may notice in applications that
+      use <application>Xft</application> that some characters appear as a box
+      with four binary digits inside.  In this case, a font set with the
+      available glyphs has not been found.  Other times, applications that
+      don't use other font families by default and don't accept substitutions
+      from <application>Fontconfig</application> will display blank lines when
+      the default font doesn't cover the orthography of the user's language.
+      This happens, e.g., with <application>Fluxbox</application> in the
+      ru_RU.KOI8-R locale.</para>
+
+      <para>In order to provide greater Unicode coverage, it is recommended
+      that you install these fonts:</para>

+    <para>For most hardware configurations, modern Xorg will automatically
+    get the server configuration correct without any user intervention. There
+    are, however, some cases where auto-configuration will be incorrect.
+    Following are some example manual configuration items that may be of use in

+
+    <sect3 id="xinput">
+    <title>Setting up X Input Devices</title>
+    <para>For most input devices, no additional configuration will be
+    necessary.  This section is provided for informational purposes only.</para>
+    
+    <para>A sample default XKB setup could look like the following (executed as

+<screen><userinput role="username">cat > /etc/X11/xorg.conf.d/xkb-defaults.conf << "EOF"

+

+  <para>Again, with modern Xorg, little or no additional configuration is

+
+<screen><userinput role="root">cat > /etc/X11/xorg.conf.d/videocard-0.conf << "EOF"

+
+  <para>Another common setup is having multiple server layouts for use in
