I've upgraded two laptops to Ubuntu 20.04 LTS. On one of them pressing Super (aka the Windows Logo key) opens the Activities overview. On the other one it doesn't, and I have to use Super+S, or Alt+F1.
The main difference between the laptops is that one uses Ubuntu on Wayland (where Super works fine), and the other one uses Ubuntu on Xorg (where Super doesn't work).
How do I make Super work on both laptops?
Would you convert your comment to an answer so I can accept it?
