          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 any error appearing on the console ? How are you starting your application ? What kind of application is it ?
