Go to display settings. Click the "star" icon on either of the displays. The icon is highlighted with a circle around it. Apply the settings. Primary screen is set.
But the highlighting around the primary screen has gone away. The next time I will open the display settings dialog, I cannot directly see which display is the primary one at the moment.
I suggest that the primary display always gets a star filled with black colour.
Oh I just saw that it in fact is highlighted with a white star.
I'd like black more because it gives better contrast on the pastel-colored screen rectangles
Scenario: have at least 2 monitors.
