I was tried chrome remote desktop app with a friend. He has a Mac. By mistake he clicked cmd + s, I do not know if that is super + s combination, the thing is it killed all my kde plasma widgets.
Is there a short way to restore it?
OK, found the solution. Was really simple, it creates a new activitie. It is as simple as got to activities, change back to the old one, and stop and delete the new one.
