<para>The <application>gdm</application> <application>PAM</application>
config files contain modules not present in a <acronym>BLFS</acronym>
installation.  The following commands will replace those files:</para>
<screen><userinput><command>cat &gt; /etc/pam.d/gdm &lt;&lt; "EOF"</command>
auth        required    pam_unix.so
auth        required    pam_nologin.so
account     required    pam_unix.so
password    required    pam_unix.so
session     required    pam_unix.so
<command>EOF</command></userinput></screen>
<screen><userinput><command>cat &gt; /etc/pam.d/gdm-autologin &lt;&lt; "EOF"</command>

<para><command>gdm</command> can be tested by executing it from a root console.</para>

<para>To automate the running of <command>gdm</command>, use the following command to
create the init.d script if your GNOME_PREFIX=/opt/gnome-&gnome-version;.  The fully qualified paths can be removed for GNOME_PREFIX=/usr:
<screen><userinput><command>cat &gt; /etc/rc.d/init.d/gdm &lt;&lt; "EOF"</command>
#!/bin/bash
# Begin $rc_base/init.d/gdm

# Based on sysklogd script from LFS-3.1 and earlier.
