	<title>How do I change the default window manager?</title>

	<para>First thing to do is to install the window manager you
	  prefer. You can find a lot of them, ready to install, in
	  pkgsrc's <filename role="pkg">wm</filename> category. After
	  a successful installation, figure out how is the
	  binary named. It will usually match package's name.</para>

	<para>Once you know how to execute the window manager, you
	  have to configure your X session to start it up. We will be
	  using ctwm in our examples (which comes with X), whose binary
	  is named <code>ctwm</code>:</para>

	  <listitem>If you are using &man.startx.1;, edit the
	    <filename>~/.xinitrc</filename> file and
	    append the following line to it:
	    <code>exec ctwm</code></listitem>
	  <listitem>If you are using &man.xdm.1;, edit the
	    <filename>~/.xsession</filename> file and append the 
	    following line to it:
	    <code>exec ctwm</code></listitem>

	<para>You can see that the content for each file is the same,
	  so you may want to create a link between them.</para>

	<para>If it is a third party item of software, you should
	  check if a version is available via the <ulink
	    url="../software/packages.html">NetBSD packages collection</ulink>.
	  Otherwise, you need to ensure the linker flags (or
	  <varname>LDFLAGS</varname>) contain 
	  <code>-L/usr/X11R7/lib, -Wl,-R/usr/X11R7/lib</code>.</para>
