Comment 22 for bug 562423

If you're setting up a new machine or one where you haven't already set a remote desktop password, this can be done from the command line;

vi ~/.gconf/desktop/gnome/remote_access/%gconf.xml

<?xml version="1.0"?>
<gconf>
        <entry name="vnc_password" mtime="1285453727" type="string">
                <stringvalue>your base64 password</stringvalue>
        </entry>
        <entry name="prompt_enabled" mtime="1285453727" type="bool" value="false"/>
        <entry name="authentication_methods" mtime="1285453735" type="list" ltype="string">
                <li type="string">
                        <stringvalue>vnc</stringvalue>
                </li>
        </entry>
        <entry name="enabled" mtime="1285453720" type="bool" value="true"/>
</gconf>
