I have a laptop running Ubuntu 20.04 LTS which is connected to an extenal monitor, while the built-in display is off (and the lid is closed). I have an external wired keyboard and mouse and when I suspend the computer I would like to be able to tap a key or click the mouse and the computer would wake up again. However, this is not the case and I end up having to lift off all the things I have sitting on my laptop and pry open the top so the computer wakes up and the monitor detects it. How could I fix this?
