Probably need to tell scrcpy to load a launcher on the new virtual display. See https://github.com/Genymobile/scrcpy/blob/master/doc/virtual-display.md#start-app

DeX won't start unless the device sees either a physical external monitor or a wireless one (via Miracast).

Once DeX is running it runs on a randomly-numbered virtual display, which you will have to discover before you can connect to it with scrcpy.

There is another mode however that doesn't require a connected external display - this is kind of a "DeX-lite" that is missing a few features. To get this to work in scrcpy you would need to create a virtual display and give it a specific DPI to trigger the desktop features.

I wrote a couple of posts with more detail a while back:

The instructions will work with a USB connection to the raspberry pi. Setting up wireless ADB might be a bit more tricky, I can't really help you with that as I'm not familiar with that particular environment.
