Full Screen HMI

The reference image includes a second HMI, also written with Qt, that demonstrates how to run a single, monolithic HMI without packaging apps into Blackberry ARchive (BAR) files.

The Full Screen HMI has a simple user interface and doesn't use the Application and Window Management components, such as the Authorization Manager (authman) or Application Launcher (launcher). To display the simple HMI instead of the Home screen, change the following line in the /var/etc/services-enabled file using elvis or vi:
Then, save the services-enabled file and restart your board. After the board restarts, the simple HMI showing the QNX logo and the target's IP address appears:

Note: It's expected that developers write their own Full Screen HMI, as the sample provided is intended just to demonstrate how to start Qt runtime and its dependencies (e.g., graphics/Screen, multimedia/mm-renderer).
