Any error message on the console ? Do you have a an Xorg server running ?

In my honest opinion you can't use Qml - Quick on xcb (On raspberry Pi) because Quick requires OpenGL ES2.
I have built Qt 5.5.1 for Raspberry Pi in 2 different modes: the first, for QWidgets applications on XOrg (xcb) or framebuffer without OpenGL ES, and a second with OpenGL ES for applications based on Quick, without Xorg.
After many tests I can't run a application based on QWidgets if it Qt was built with OpenGL ES. -
Do you have an Xorg server running ?
-
Do you have any error appearing on the console ? How are you starting your application ? What kind of application is it ?
-
I hope you will resolve yourself.
Anyway I have a lot of open projects based on Raspberry Pi, someone is a console application, some other is xcb, some other QtQuick with OpenGL ES. If you require to have professional support please contact me. I'm gmt+1 (Italy).
