Description
If you have two screens configured in such a way that they are not one large virtual desktop, e.g. you cannot move windows between them, then for most X applications you can choose which screen to start the app by setting the DISPLAY variable, e.g. open up a terminal on the first display and then start something else on the second display:
DISPLAY=:0.1 xterm
If you do that with a Qt 5 app, it will start up on the first display anyway.
I didn't figure out why yet; when XOpenDisplay is called, the Display object does have the display name as given.
