I have ubuntu 18.04 LTS installed with gnome 3.28.1. In settings I can't find a switcher which turns built-in display off. I proceeded settings->devices->displays. And there is no buttons as were on 17.10. How can I turn the display off either via bash or GUI?
See a screenshot

Use the Single display tab instead of Join displays tab.
