Description of problem: I have T500 in docking station connected to external monitor. When I lock the screen and then undock the laptop (i.e. disconnect the external monitor) the laptop screen flickers and my desktop appears for a second then unlock dialog is displayed. Also the same happens the other way - when the external monitor is connected. Version-Release number of selected component (if applicable): gnome-screensaver-2.28.3-15.el6 How reproducible: 100% Steps to Reproduce: 1. lock the screen 2. connect/disconnect external monitor Actual results: Desktop appears for a brief moment Expected results: the locked screen should remain blank all the time.
Similar behavior can be observed in multi-user env. When I have two users logged in, and I logout one of them then I can see the other's desktop for a brief moment before gdm or lock screen kicks in. This is probably related to Xorg fast user switching.
