Hi, I have developed a python application that uses Pyglet library to show videos and images using HDMI port. It runs well on Raspbian but does Balena OS allows to run user applications that uses display since when i deployed the app, it continues to show Balena Logo

PS: I dont want to use BalenaDash since it uses Browser to show media

Hey there! Your app should work fine on balenaOS. Any container can setup an X server to communicate to the display in whatever way you want (this is what balenaDash does under the hood). Check [https://github.com/balena-io/resin-electronjs/blob/master/Dockerfile.template#L72-L74](https://github.com/balena-io/resin-electronjs/blob/master/Dockerfile.template#L72-L74) and [https://github.com/balena-io/resin-electronjs/blob/master/app/start.sh](https://github.com/balena-io/resin-electronjs/blob/master/app/start.sh) for another example
