Public bug reported: My monitors become unavailable and hard to configure after blanking, or switching to a different input, let alone unplugging.
I can boot into 14.04 and do not see this problem. It is present in 16.04. I did not use the releases in between on this system. It is a core-i7 machine, so the graphics is Intel and is on the motherboard. I'm using all three of the outputs provided by my Z97-Deluxe mobo. I have had to disable blanking because otherwise I will definitely have at least one monitor no longer active when I wake up the system. Getting it active again requires a number, at least 3, of attempts to "use this monitor" in the Display widget. plus un- mirroring and putting it back in its proper place. This also happens if I switch the monitors to using another input, which I wanted to do because I have two systems and I'd like to switch the monitors between them. I'm having to use a workspace of ssh+tmux instances instead, which has some drawbacks of its own, but is at least workable.
