BalenaOS Jetson Nano |  X server Docker Container & Box64 Unity3D Docker Container 
Hey. I might be in a special use case here. 

We're trying to deploy graphical interfaces OTA with BalenaOS on ARM architecture. The license from Unity was quite expensive to compile to ARM so before we take that route I thought I'd try with Box64.

I've got one container managing the X server through this https://github.com/balena-labs-projects/xserver
And another container running the exported unity project. 

But nothing shows up on the display other than a mouse cursor that i can move around once plugged in..


Heres the docker container for the Unity project:

```

FROM balenalib/jetson-nano-ubuntu:latest

RUN apt update && apt install wget -y

RUN wget https://ryanfortner.github.io/box64-debs/box64.list -O /etc/apt/sources.list.d/box64.list
RUN wget -O- https://ryanfortner.github.io/box64-debs/KEY.gpg | gpg --dearmor -o /usr/share/keyrings/box64-debs-archive-keyring.gpg 
RUN apt update && apt install box64 -y


WORKDIR /usr/src/app
COPY JetsonNanoTest .
COPY entry.sh .
RUN chmod +x hmi.x86_64
RUN chmod +x entry.sh

RUN apt install libxss1 libwayland-egl1 libwayland-cursor0 libxkbcommon0 libxkbcommon-x11-0 libxcursor1 libxinerama1 libxi6 libxrandr2 libxxf86vm1  -y


ENV BOX64_LOG =2
#ENTRYPOINT ["/bin/bash", "/usr/src/app/entry.sh"]

CMD [ "box64" ,"/usr/src/app/hmi.x86_64"]
```

Docker-compose file:

```
version: '2.1'

volumes:
  x11:


services:

  xserver:
    build: ./Containers/XServer
    restart: always
    privileged: true
    network_mode: host
    volumes:
      - 'x11:/tmp/.X11-unix'

  emulator:
    build: ./Containers/emulator
    restart: always
    privileged: true
    network_mode: host
    devices:
      - /dev/dri
    group_add:
      - video
    volumes:
      - 'x11:/tmp/.X11-unix'
```


The display is default :0 , is there any specific command that Box64 needs to target a display somehow?
