Slackware 13.0 x86_64 is released as stable! Thanks to everyone who
helped make this release possible -- see the RELEASE_NOTES for the
credits. The ISOs are off to the replicator. This time it will be a
6 CD-ROM 32-bit set and a dual-sided 32-bit/64-bit x86/x86_64 DVD.
We're taking pre-orders now at store.slackware.com. Please consider
picking up a copy to help support the project. Once again, thanks to
the entire Slackware community for all the help testing and fixing
things and offering suggestions during this development cycle.
As always, have fun and enjoy! -P.

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?
