Fn key to blank screen also locks screen (i.e. logs out)

[tinymarsracing]

This was different in Ubuntu 18.04 (and Windows). There it just turns off the screen and when you move your mouse again, there is no need to login. I'm using this functionality a lot because I don't use automatic blank screen - I prefer controlling that manually. Not sure what package controls that, possibly a udev rule?

(PS: I was thinking about whether this is actually a bug or a feature change. But I reached the conclusion that it actually *is* a bug because turning off the screen and locking the OS are two independent actions - you can also lock the OS without locking the screen and the fn key clearly refers to the screen.)
