Problem with an application using the graphical subsystem weston on the STM32MP157F-DK2 board

[Forti61]

In the file "Problem description.pdf" you find a description of my problem.

I am using visualgdb to compile a Linux application using the GTK-Graphic running on the A7 core of the STM32MP157F-DK2 board.

The build process principally works correctly, but there is a problem with user privilege settings.

Does sombedy have any ideas how to tackle this problem ?

Hello @Forti61,
The behavior you have looks completely normal, and your PDF well summarize it :

• Graphical application cannot be executed by root user, but only by weston.
• If your IDE execute your program as root user, it will not work

I do not know your editor, but you certainly have a way to execute your program with a different user privilege.

Kind regards,
Erwan.
