Comment 8 for bug 871560

I can confirm that "gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'" works but it's really not a workable solution for me at all because it disables screen locking system wide. I still want to lock my screen manually when I have sensitive documents up but I don't require the screen to lock every time I suspend. In Ubuntu 11.04 with Gnome 2 it used to be possible to not have the screen lock on suspend while still having the option to manually lock the screen in the session menu.
