-<p>As Linux becomes more and more useful as a desktop operating system, many users find
-it desirable for the machine to boot straight into a graphical environment. For this, you
-will need to tell Slackware to boot straight into X, and assign a graphical login
-manager. Slackware ships with three graphical login tools, <tt
-class="COMMAND">xdm</tt>(1), <tt class="COMMAND">kdm</tt>, and <tt
-class="COMMAND">gdm</tt>(1).</p>
-
-<p><tt class="COMMAND">xdm</tt> is the graphical login manager shipped with the X.org
-system. It's ubiquitous, but not as fully features as alternatives. <tt
-class="COMMAND">kdm</tt> is the graphical login manager shipped with KDE, The K Desktop
-Environment. Finally, <tt class="COMMAND">gdm</tt> is the login manager shipped with
-GNOME. Any of the choices will allow you to log in as any user, and choose what desktop
-you wish to use.</p>
-
-<p>Unfortunately, Slackware doesn't include a nice program like <tt
-class="COMMAND">xwmconfig</tt> for choosing what login manager to use, so if all three
-are installed you may have to do some editing to choose your preference. But first, we'll
-discuss how to boot into a graphical environment.</p>
-
-<p>In order to start X at boot, you need to boot into run-level 4. Run-levels are just a
-way of telling <tt class="COMMAND">init</tt>(8) to do something different when it starts
-the OS. We do this by editing the config file for <tt class="COMMAND">init</tt>, <tt
-class="FILENAME">/etc/inittab</tt>.</p>
-
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="PROGRAMLISTING">
-# These are the default runlevels in Slackware:
-# 0 = halt
-# 1 = single user mode
-# 2 = unused (but configured the same as runlevel 3)
-# 3 = multiuser mode (default Slackware runlevel)
-# 4 = X11 with KDM/GDM/XDM (session managers)
-# 5 = unused (but configured the same as runlevel 3)
-# 6 = reboot
-
-# Default runlevel. (Do not set to 0 or 6)
-id:3:initdefault:
-</pre>
-</td>
-</tr>
-</table>
-
-<p>In order to make Slackware boot to a graphical environment, we just change the 3 to a
-4.</p>
-
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="PROGRAMLISTING">
- # Default runlevel. (Do not set to 0 or 6)
- id:4:initdefault:
-</pre>
-</td>
-</tr>
-</table>
-
-<p>Now Slackware will boot into runlevel 4 and execute <tt
-class="FILENAME">/etc/rc.d/rc.4</tt>. This file starts up X and calls whatever login
-manager you've chosen. So, how do we choose login managers? There are a few ways to do
-this, and I'll explain them after we look at <tt class="FILENAME">rc.4</tt>.</p>
-
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="PROGRAMLISTING">
- # Try to use GNOME's gdm session manager:
- if [ -x /usr/bin/gdm ]; then
- exec /usr/bin/gdm -nodaemon
- fi
-
- # Not there? OK, try to use KDE's kdm session manager:
- if [ -x /opt/kde/bin/kdm ]; then
- exec /opt/kde/bin/kdm -nodaemon
- fi
-
- # If all you have is XDM, I guess it will have to do:
- if [ -x /usr/X11R6/bin/xdm ]; then
- exec /usr/X11R6/bin/xdm -nodaemon
- fi
-</pre>
-</td>
-</tr>
-</table>
-
-<p>As you can see here, <tt class="FILENAME">rc.4</tt> first checks to see if <tt
-class="COMMAND">gdm</tt> is executable, and if so runs it. Second on the list is <tt
-class="COMMAND">kdm</tt>, and finally <tt class="COMMAND">xdm</tt>. One way of choosing a
-login manager is to simply remove the ones you don't wish to use using <tt
-class="COMMAND">removepkg</tt>. You can find out more about <tt
-class="COMMAND">removepkg</tt> in <a href="package-management.html">Chapter 18</a>.</p>
-
-<p>Optionally, you can remove the executable permission from those files that you don't
-want to use. We discuss <tt class="COMMAND">chmod</tt> in <a
-href="filesystem-structure.html">Chapter 9</a>.</p>
-
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="SCREEN">
-<samp class="PROMPT">#</samp> <kbd class="USERINPUT">chmod -x /usr/bin/gdm</kbd>
-</pre>
-</td>
-</tr>
-</table>
-
-<p>Finally, you can just comment out the lines for the login manager you don't want to
-use.</p>
-
-<table border="0" bgcolor="#E0E0E0" width="100%">
-<tr>
-<td>
-<pre class="PROGRAMLISTING">
- # Try to use GNOME's gdm session manager:
- # if [ -x /usr/bin/gdm ]; then
- # exec /usr/bin/gdm -nodaemon
- # fi
-
- # Not there? OK, try to use KDE's kdm session manager:
- if [ -x /opt/kde/bin/kdm ]; then
- exec /opt/kde/bin/kdm -nodaemon
- fi
-
- # If all you have is XDM, I guess it will have to do:
- if [ -x /usr/X11R6/bin/xdm ]; then
- exec /usr/X11R6/bin/xdm -nodaemon
- fi
-</pre>
-</td>
-</tr>
-</table>
-
-<p>Any lines preceded by the hash mark (<var class="LITERAL">#</var>) are considered
-comments and the shell silently passes them. Thus, even if <tt class="COMMAND">gdm</tt>
-is installed and executable, the shell (in this case <tt class="COMMAND">bash</tt>) won't
-bother checking for it.</p>
