Yesterday I had ny computer working just fine with the laptop monitor and a secondary monitor used as additional desktop space. I could easily move windows between the two by dragging. Today, I turned on the computer with the extra monitor as usual. The laptop screen showed the usual logo but then all of the activity switched to the secondary monitor. The laptop screen is blank. I tried to detect in the settings but it says there is only on screen.
Any help is appreciated
