Public bug reported: I find sometimes that if I plug in my monitor into my laptop (via an HDMI port, and and then HDMI to DVI connector) the monitor doesn't seem to be recognized by ubuntu and no image displays on it. I have gotten around this issue by having my laptop go to sleep and then plugging it in then, at which point I could wake it up and things would generally work. It seems lately though that the lock screen is just frozen upon waking up (though not always, I can't seem to notice any pattern or triggers), and therefore I usually have to restart X.
What I expect to happen is to be able to plug in my secondary monitor at any point, at the lock screen, when at the desktop, or when the laptop is closed or asleep, and then just have it recgonized and work without needing to reboot or restart the display server.
