Sorry to take so long.

You can get X11 to run on target despite all attempts to lock it down.
Helps if one edits this
sudo cat /var/sota/storage/docker-compose/docker-compose.yml

so it looks like this

services:
  weston:
    cap_add:
    - CAP_SYS_TTY_CONFIG
    container_name: App_weston
    device_cgroup_rules:
    - c 4:0 rmw
    - c 4:7 rmw
    - c 13:* rmw
    - c 199:* rmw
    - c 226:* rmw
    environment:
      ACCEPT_FSL_EULA: '1'
    image: torizon/weston-vivante@sha256:b39bd723e554a95522bd6774796d6af7cac7cf4960e1c142b9a6f45e62691f45
    network_mode: host
    volumes:
    - source: /tmp
      target: /tmp
      type: bind
    - source: /dev
      target: /dev
      type: bind
    - source: /run/udev
      target: /run/udev
      type: bind
version: '2.4'

Then cold boot first.

docker run --rm -d -v /tmp:/tmp -v /var/run/dbus:/var/run/dbus -v /dev/galcore:/dev/galcore --device-cgroup-rule='c 199:* rmw' seasonedgeek/xclock-demo
