Hi @rawmance !

I have an update to share with you, although it is most probably not so useful.

It is related to the IVI shell on Weston.

After going to Weston’s source code, I found a weston.ini.in example for IVI shell:

Important observation:

  • I went for the branch 10.0 as we have in our Bookworm container the weston 10.0.1.
  • This is not the “final” file. I had to
    • replace @westondatadir@ with /usr/share/weston, and
    • replace @bindir@ with /usr/bin

After modifying the file, I placed it on the module (outside containers) in /home/torizon/weston-ivi/weston.ini

Then, I killed all containers running on the module (e.g. $ docker rm $(docker stop $(docker ps -a -q))) and ran the following command on the module to launch the Weston container using IVI shell:

$ docker run -e ACCEPT_FSL_EULA=1 --rm --name=weston \
--net=host --cap-add CAP_SYS_TTY_CONFIG \
-v /dev:/dev -v /tmp:/tmp -v /run/udev/:/run/udev/ \
-v /home/torizon/weston-ivi/:/etc/xdg/weston/ \
--device-cgroup-rule='c 4:* rmw' --device-cgroup-rule='c 13:* rmw' --device-cgroup-rule='c 199:* rmw' --device-cgroup-rule='c 226:* rmw' \
torizon/weston-vivante:$CT_TAG_WESTON_VIVANTE --tty=/dev/tty7

Some comments:

  • The command above is based on the command from the section Debian With Weston Wayland Compositor of High performance, low power Embedded Computing Systems | Toradex Developer Center
  • Because of how this container image works (specifically due to dos2unix program) I must bind mount the folder /home/torizon/weston-ivi on top of the folder /etc/xdg/weston instead of mounting only the file weston.ini.
  • I removed the --developer in order to use the weston.ini from /etc/xdg/weston instead of from /etc/xdg/weston-dev

With all this, I had access to the following on HDMI:

And I could launch applications which will stay on half screen, as you need:

A general comment:

  • To launch the applications since the startup of the container, I think you can edit the entry point of the container (there is more than one way to do this), so you can launch your applications.

A potential issue:

  • Quickly looking into IVI shell’s source code, seems like the panel is hard coded. I could not find a way to remove it (maybe it is possible and I just didn’t find a way…).

Let us know if this helps you :slight_smile:
