[Feature Request] Add casting of xserver support

[ThaDaVos]

I am currently looking into a way to extend on this image to add casting support, for example automatic casting to a Miracast adapter (compatible device) (or Chromecast).

Is this something you've looked into? Maybe up front know if even would be possible with your base image?

I see there are already some projects for it out there for linux:
https://gitlab.gnome.org/GNOME/gnome-network-displays
albfan/miraclecast#4

So, maybe we can look into this together perhaps even

I just went with it, and I can get it working till the point the gnome-netwerk-displays is booted - sadly I need a real Linux machine (not Windows with WSL) to actually test it:
