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.

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?

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.
