<para>
The GDM daemon is configured using the
<filename>/etc/gdm/custom.conf</filename> file.
Default values are stored in GConf in the
<filename>gdm.schemas</filename> file. It is recommended that end-users
modify the <filename>/etc/gdm/custom.conf</filename> file
because the schemas file may be overwritten when the user updates their
system to have a newer version of GDM.
</para>
<important>
<para>
If the system-wide <application>D-BUS</application> daemon was
running during the installation of <application>gdm</application>,
ensure you stop and restart the <application>D-BUS</application>
daemon before attempting to start <command>gdm</command>.
</para>
</important>
<para>
<command>gdm</command> can be tested by executing it as the
<systemitem class="username">root</systemitem> user. If you wish to stop
it you will need to go to a different tty and then kill it.
