Is there a way to take a screenshot of the gnome shell activities screen i.e the screen that pops up on pressing the Win key or Alt+F1? The PrintScr button works normally but doesn't seem to work when I'm on the activities screen. Is this normal behavior? If yes, are there workarounds?
Open up the gnome-screenshot (Alt+F2 and type
gnome-screenshot --interactive) tool and enable "Grab the whole desktop" and then enable "Grab after a delay of 5 seconds"
Then simply click "Take Screenshot" and bring up your Activities screen by pressing Win/Super key and in 5 seconds it will take a Screenshot.
Hope that helps! :)
