As temporary workaround - you can add this option to your lightdm-gtk-greeter.conf: active-monitor=0

Fix is commited to trunk version, so it will be a part of the next release. -- You received this bug notification because you are a member of LightDM Gtk+ Greeter Development Team, which is subscribed to lightdm-gtk- greeter in Ubuntu. https://bugs.launchpad.net/bugs/1449567 Title: Cannot see login box on a locked screen Status in lightdm-gtk-greeter package in Ubuntu: New Bug description: 1.
