Connecting a Controller

I am trying to follow instructions to setup an xbox controller with QGroundControl but am having some issues. I have toggled ‘Virtual Joystick’ in general settings and get stuck there. Do I have to plug in the PX4 first? I have just installed today and don’t know where to go from here.

Virtual Joystick is not related to using a joystick. That is to use your thumbs on the tablet screen for control. In order to setup a joystick you need to connect to a vehicle and then if the joystick is plugged on an recognized you will get a Joystick setup page that shows up.
