I have found a workaround: for some reason, the password dialog wants to only show up on one of the monitors, but only the one on which the mouse is when showing the password dialog is displaying "stuff" (stuff being anything else besides the top bar). So what I do when I don't see the password dialog is to press escape once, then move the mouse to the other monitor, and press escape again.
This may have something to do with the fact that I'm using nVidia drivers (there are always some annoyances with it and two-monitor setup). Nouveau had better behaviour with two monitors, but I have not been using it for a very long time. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-screensaver in Ubuntu. https://bugs.launchpad.net/bugs/848562 Title: gnome-shell lock screen does not display password prompt Status in GNOME Screensaver: Invalid Status in GNOME Shell: Incomplete Status in “gnome-screensaver” package in Ubuntu: Confirmed Bug description: I have two monitors, the laptop screen and an external one connected via display port. When I do 'ctrl-alt-L' in gnome-shell to lock the screen, the laptop screen displays the screen background and the second monitor displays whatever was on it before locking the screen. When I press a key, no password prompt appears - the laptop continues to display the background. However, entering the password at this point unlocks the computer.
