Cannot disable user switching

[Pausanias]

On a fully patched feisty, no matter what I do, I cannot disabled the "Switch user" button when the screen is locked. I have turned off /apps/gnome-screensaver/user_switch_enabled, and turned on /desktop/gnome/lockdown/disable_user_switching. No matter what I do, the login screen still displays the "Switch User..." button.

Same problem here.

With /desktop/gnome/lockdown/disable_user_switching only the Switch user Button in the logout menu disappears.

Add following entries to /etc/gconf/gconf.xml.mandatory/%gconf-tree.xml

<?xml version="1.0"?>
<gconf>
    <dir name="apps">
        <dir name="gnome-screensaver">
            <entry name="user_switch_enabled" mtime="1181222573" schema="/schemas/apps/gnome-screensaver/user_switch_enabled" type="bool" value="false" />
        </dir>
    </dir>
</gconf>

gnome-screensaver also doesn't respect the "user_switch_enabled" setting when making it mandatory.

Marcel, your suggested change to %gconf-tree.xml has no effect even after a restart. The switch user button still appears.

Marking this as confirmed as several have reported the same experience.

There's a patch for g-s 2.19 at http://bugzilla.gnome.org/show_bug.cgi?id=469890

[Peter Meiser (meiser79)]

Issue is fixed in g-s SVN trunk (http://svn.gnome.org/viewcvs/gnome-screensaver/trunk/src/gs-lock-plug.c?r1=1272&r2=1273).

The diff can also be used for 2.18.1 which is in Feisty.

   * New upstream release

    * Hide switch button if not enabled. Fixes #442853

      extra 'if' statement.

Found a workaround for those still with Feisty.

sudo mv /usr/bin/gdmflexiserver /usr/bin/FOOgdmflexiserver

This will cause the Switch User button to have no effect.
