Comment 43 for bug 951000

@Sebastien, thanks for your reply.
I have tried the patch; it works good as expected and I have no issue with it.

The reason I tried "dbus-launch gsettings set org.gnome.desktop.lockdown disable-lock-screen true" was because you commented on our private bug and ask us to try dbus-launch. Therefore, I assumed you still expected my reply.

Your patch works perfectly on the machine I tested, but I still hope to understand the reason why dbus-launch gsettings does not work for you. In the old guest-account, it does the following

  su $USER <<EOF
  gconftool-2 --set --type bool /desktop/gnome/lockdown/disable_lock_screen True
EOF

Since it su to guest user, it is reasonable to me that the gsetting can be set properly for guest user, and that is also what I see when I made tests to use "dbus-launch gsettings". I will be very happy to know what kind of difference causes "dbus-launch gsettings" not function in your side but my side.
