This will also solve issues with laptops using docking station (and attached screens): when you dock/undock laptop, Plasma crashes almost all the times.

Older monitors didn't do that; but Qt 5.5 tries to be honest about it: the QScreen is destroyed whenever its corresponding monitor is disconnected, QGuiApplication::primaryScreen() returns null, and so on. KDE developers have been complaining. So in Qt 5.6 we made it keep the last-remaining QScreen as a fake instance, whenever the last monitor is disconnected. The main patch is here https://codereview.qt-project.org/#/c/138201/ You might need to cherry-pick that (a094af001795c9651b299d700a992150d1aba33a in qtbase) for as long as you are shipping Qt 5.5, to get Kubuntu behaving decently. It's relevant on Ubuntu 16.04. Too bad that Ubuntu LTS is not shipping the LTS Qt 5.6 release, but I know we are behind on our release schedule. Some users have also reported that their laptop's screen disconnects when it sleeps. And I have often experienced 5.5-based builds of Creator crashing or disappearing when I switch machines on my KVM. So, sorry that we didn't fix it sooner. It was my mistake for believing that modeling disappearing screens "correctly" was a good idea: it turned out to be a platform inconsistency which developers were not ready for.
