Fixed on vivid. I attempted to connect using the ethernet interfaces address (Xephyr :1 -query <address>) and was not able to when this option is enabled.

It is desirable for these to be limited to a particular interface to limit who can connect (i.e. only allow local connections on 127.0.0.1). [Test Case] 1. Enable the VNC server in LightDM in lightdm.conf: [VNCServer] enabled=true listen-address=127.0.0.1 2. Start LightDM With this setup you should only be able to make a local connection. [Regression potential] Low. If the option is not set LightDM has the old behaviour.
