Nope! Plasma has a nice settings page dedicated to to this power related configuration, so you click exactly what you want to happen and forget about it. I configured plasma to work almost identically to gnome with the overview and gestures and it is so snappy. Still hope that the gnome devs work out a way to make these options more accessible, but even if they added those there’s no way I’d switch back now!
At mine it was not. Hotspots and the like that stayed up for too long were flagged and action was taken to have them disabled and the student reprimanded.
