Bug Description

Consider the following, real scenario:

I have my office computer set to automatically lock after 5 minutes. I leave for the weekend and the following day I SSH to my computer with a local redirect to :5900 and start x11vnc -display :0. I unlock my screen and proceed to use the computer over VNC. I then disconnect from VNC. I later return to my office computer to find it unlocked, in the state I left the session on VNC.

Expected behaviour: the screensaver automatically locks the computer after 5 minutes of inactivity, regardless of the VNC session.

Ubuntu: 12.04.5 (Precise)
gnome-screensaver: 3.4.1-0ubuntu1

This is a fundamental bug in the design of X11 and cannot be easily fixed within X11.

You should manually lock your screen if a locked session is important to you.

Please continue to report any other bugs you may find.
