Something has to draw a window over the user's session. Lightdm does _not_ do this.
If you use dm-tool to tell lightdm to lock the screen, it calls logind over dbus, and whatever you use in the user's session to hide the screen needs to receive the dbus signal from logind to lock the screen. In Unity, it is gnome-screensaver, in GNOME, it is gnome-shell. I don't believe XScreensaver listens to logind signals over dbus, hence, if you want to use XScreensaver in lubuntu, you need to call it to lock the screen before you use dm-tool. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1205384 Title: Lock can be circumvented by switching to console To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lightdm/+bug/1205384/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
