+
+<p>Starting with Slackware-10.0, the X Window environment in Slackware is provided by
+Xorg. X is responsible for providing a graphical user interface. It is independent from
+the operating system, unlike Windows or the MacOS.</p>
+
+<p>The X Window System is implemented through many programs that run in userland. The two
+main components are the server and the window manager. The server provides the lowlevel
+functions for interacting with your video hardware, thus it is system specific. The
+window manager sits on top of the server and provides the user interface. The advantage
+to this is you can have many different graphical interfaces by simply changing the window
+manager you use.</p>
+
+<p>Configuring X can be a complex task. The reason for this is the vast numbers of video
+cards available for the PC architecture, most of which use different programming
+interfaces. Luckily, most cards today support basic video standards known as VESA, and if
+your card is among them you'll be able to start X using the <tt
+class="COMMAND">startx</tt> command right out of the box.</p>
+
+<p>If this doesn't work with your card, or if you'd like to take advantage of the
+high-performance features of your video card such as hardware acceleration or 3-D
+hardware rendering, then you'll need to reconfigure X.</p>
+
+<p>To configure X, you'll need to make an <tt class="FILENAME">/etc/X11/xorg.conf</tt>
+file. This file contains lots of details about your video hardware, mouse, and monitor.
+It's a very complex configuration file, but fortunately there are several programs to
+help create one for you. We'll mention a few of them here.</p>
+
+<div class="SECT1">
+<h1 class="SECT1"><a id="X-WINDOW-SYSTEM-XORGCONFIG"
+name="X-WINDOW-SYSTEM-XORGCONFIG">6.1 <tt class="COMMAND">xorgconfig</tt></a></h1>
+
+<p>This is a simple menu driven frontend that's similar in feel to the Slackware
+installer. It simply tells the X server to take a look at the card, and then set up the
+best initial configuration file it can make based on the information it gathers. The
+generated <tt class="FILENAME">/etc/X11/xorg.conf</tt> file should be a good starting
+point for most systems (and should work without modification).</p>
+
+<p>This is a text-based X configuration program that's designed for the advanced system
+administrator. Here's a sample walkthrough using <tt class="COMMAND">xorgconfig</tt>.
+First, start the program:</p>
+
+<table border="0" bgcolor="#E0E0E0" width="100%">
+<tr>
+<td>
+<pre class="SCREEN">
+<samp class="PROMPT">#</samp> <kbd class="USERINPUT">xorgconfig</kbd>
+</pre>
+</td>
+</tr>
+</table>
+
+<p>This will present a screenful of information about <tt
+class="COMMAND">xorgconfig</tt>. To continue, press <kbd class="USERINPUT">ENTER</kbd>.
+<tt class="COMMAND">xorgconfig</tt> will ask you to verify you have set your <tt
+class="ENVAR">PATH</tt> correctly. It should be fine, so go ahead and hit <kbd
+class="USERINPUT">ENTER</kbd>.</p>
+
+<div class="FIGURE"><a id="X-WINDOW-SYSTEM-1" name="X-WINDOW-SYSTEM-1"></a>
+<p><b>Figure 6-1. <tt class="COMMAND">xorgconfig</tt> Mouse Configuration</b></p>
+
+<p><img src="x-window-system/xorgconfig1-w.png" /></p>
+</div>
+
+<p>Select your mouse from the menu presented. If you don't see your serial mouse listed,
+pick the Microsoft protocol -- it's the most common and will probably work. Next <tt
+class="COMMAND">xorgconfig</tt> will ask you about using <var
+class="OPTION">ChordMiddle</var> and <var class="OPTION">Emulate3Buttons</var>. You'll
+see these options described in detail on the screen. Use them if the middle button on
+your mouse doesn't work under X, or if your mouse only has two buttons (<var
+class="OPTION">Emulate3Buttons</var> lets you simulate the middle button by pressing both
+buttons simultaneously). Then, enter the name of your mouse device. The default choice,
+<tt class="FILENAME">/dev/mouse</tt>, should work since the link was configured during
+Slackware setup. If you're running GPM (the Linux mouse server) in repeater mode, you can
+set your mouse type to <tt class="FILENAME">/dev/gpmdata</tt> to have X get information
+about the mouse through <tt class="COMMAND">gpm</tt>. In some cases (with busmice
+especially) this can work better, but most users shouldn't do this.</p>
+
+<p><tt class="COMMAND">xorgconfig</tt> will ask you about enabling special key bindings.
+If you need this say &#8220;<kbd class="USERINPUT">y</kbd>&#8221;. Most users can say
+&#8220;<kbd class="USERINPUT">n</kbd>&#8221; -- enter this if you're not sure.</p>
+
+<div class="FIGURE"><a id="X-WINDOW-SYSTEM-2" name="X-WINDOW-SYSTEM-2"></a>
+<p><b>Figure 6-2. <tt class="COMMAND">xorgconfig</tt> Horizontal Sync</b></p>
+
+<p><img src="x-window-system/xorgconfig2-w.png" /></p>
+</div>
+
+<p>In the next section you enter the sync range for your monitor. To start configuring
+your monitor, press <kbd class="USERINPUT">ENTER</kbd>. You will see a list of monitor
+types -- choose one of them. Be careful not to exceed the specifications of your monitor.
+Doing so could damage your hardware.</p>
+
+<div class="FIGURE"><a id="X-WINDOW-SYSTEM-3" name="X-WINDOW-SYSTEM-3"></a>
+<p><b>Figure 6-3. <tt class="COMMAND">xorgconfig</tt> Vertical Sync</b></p>
+
+<p><img src="x-window-system/xorgconfig3-w.png" /></p>
+</div>
+
+<p>Specify the vertical sync range for your monitor (you should find this in the manual
+for the monitor). xorgconfig will ask you to enter strings to identify the monitor type
+in the <tt class="FILENAME">xorg.conf</tt> file. Enter anything you like on these 3 lines
+(including nothing at all).</p>
+
+<div class="FIGURE"><a id="X-WINDOW-SYSTEM-4" name="X-WINDOW-SYSTEM-4"></a>
+<p><b>Figure 6-4. <tt class="COMMAND">xorgconfig</tt> Video Card</b></p>
+
+<p><img src="x-window-system/xorgconfig4-w.png" /></p>
+</div>
+
+<p>Now you have the opportunity to look at the database of video card types. You'll want
+to do this, so say &#8220;<kbd class="USERINPUT">y</kbd>&#8221;, and select a card from
+the list shown. If you don't see your exact card, try selecting one that uses the same
+chipset and it will probably work fine.</p>
+
+<p>Next, tell <tt class="COMMAND">xorgconfig</tt> how much RAM you have on your video
+card. <tt class="COMMAND">xorgconfig</tt> will want you to enter some more descriptive
+text about your video card. If you like, you can enter descriptions on these three
+lines.</p>
+
+<p>You'll then be asked which display resolutions you want to use. Again, going with the
+provided defaults should be fine to start with. Later on, you can edit the <tt
+class="FILENAME">/etc/X11/xorg.conf</tt> file and rearrange the modes so 1024x768 (or
+whatever mode you like) is the default.</p>
+
+<p>At this point, the <tt class="COMMAND">xorgconfig</tt> program will ask if you'd like
+to save the current configuration file. Answer yes, and the X configuration file is
+saved, completing the setup process. You can start X now with the <tt
+class="COMMAND">startx</tt> command.</p>
