Dual screens Single DRM

[sebastian-verge]

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-c... 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

torizon@verdin-imx8mp-15207741:~$ docker compose up dash --no-deps

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

I asked over in the Toradex community: https://community.toradex.com/t/25126

You can see how our issues were resolved there.

Thank you!
