EGL Error : Could not create the egl surface: error = 0x3003

[PaulMax]

I've read that you can solutionate this problem with one of the followings:

export QT_QPA_EGLFS_FB=/dev/fb2

but where do I write that: I mean export..... How does that work? Any documentation.....

Thanks in advance

You write that in your shell, before launching your application.

@PaulMax When starting the app from QtCreator go to "Projects" (on the left side), Build & Run, select Run and then go to "Run Environment" - add QT_QPA_EGLFS_FB variable there.
