Where the cinematics app autostarts in the tdx-reference-multimedia-image?

I need Linux with Qt and I choose
as a starting point.

After successfully loading I see Qt5_CinematicExperience application running.
But I have not found where it is started?
I have check all suggestions from the article How to Autorun application at the start up in Linux.
And there are no references to this application.

Where is Qt5_CinematicExperience launched?
Is anywhere a description of tdx-reference-multimedia-image?
Is tdx-reference-multimedia-image a good base for building a system with Qt?

I have found the roots of the application launching.

systemd runs x-window-manager script

x-window-manager script starts Qt5_CinematicExperience

while [ $RET -ne 0 ]; do
        cd /usr/share/cinematicexperience-1.0

Perfect that it is working. Thanks for the feedback.

Has anyone figured out how stop this from autobooting? Where is the x-window-manager script?

Hello, jeffbelz!

To temporary stop this you can try
systemctl stop wayland-app-launch.service
Or disable
systemctl disable wayland-app-launch.service

You can find reference to demo launcher in the

You can edit
and remove demo and add your application

And to exclude service from Yocto build look into
