Dual screens Single DRM

I have been following the Multi-display - Redirecting the output - one DRM interface document.

I can get each app working individually. For some reason I cannot get both applications to start at the same time.

I started by getting the wayland app-ids:

torizon@verdin-imx8mp-15207741:~$ docker compose run --rm -e WAYLAND_DEBUG=1 infotainment 2>&1 | grep set_app_id [3625339.789] -> xdg_toplevel@24.set_app_id("StarOSApp") ^C torizon@verdin-imx8mp-15207741:~$ docker compose run --rm -e WAYLAND_DEBUG=1 dash 2>&1 | grep set_app_id [3645913.156] -> xdg_toplevel@24.set_app_id("StarDashApp")

I added these values to my weston.ini:

torizon@verdin-imx8mp-15207741:~$ cat weston.ini [core] idle-time=0 require-input=false xwayland=true modules=screen-share.so shell=kiosk-shell.so #require-outputs=all-found [shell] panel-position=top locking=false allow-zap=true num-workspaces=1 [output] name=HDMI-A-2 mode=preferred app-ids=StarDashApp [output] name=HDMI-A-1 mode=preferred app-ids=StarOSApp

The docker compose file I am using is as close to https://github.com/toradex/torizon-samples/blob/bookworm/multi-display/single-drm-interface/docker-compose.arm64.yml as I can manage. I can post it if that helps?

When I try to start the second container I get the following:

torizon@verdin-imx8mp-15207741:~$ docker stats --no-stream CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS 3a0b29ca1608 live-infotainment-1 44.68% 111MiB / 7.754GiB 1.40% 3.43kB / 0B 0B / 61.4kB 9 7e96d7a3546c live-weston-1 16.12% 18.26MiB / 7.754GiB 0.23% 0B / 0B 32.8kB / 307kB 11 torizon@verdin-imx8mp-15207741:~$ docker compose up dash --no-deps [+] Running 1/1 ✔ dash Pulled 0.7s [+] Running 1/0 ✔ Container live-dash-1 Created 0.0s Attaching to live-dash-1 live-dash-1 | Loaded language: "en" live-dash-1 | Font "Inter-Bold.ttf" loaded live-dash-1 | Font "Inter-Medium.ttf" loaded live-dash-1 | Font "Inter-Regular.ttf" loaded live-dash-1 | Font "Inter-SemiBold.ttf" loaded live-dash-1 exited with code 139

I am really hoping you can point me to where I can even start to work out what is going on!
