X11 and OpenGL

[goli]

How can I build Qt for X11 with OpenGL support?
I have Hardware acceleration on my device, but when i config the qt(qml) application to work with opengl
i can't see any improvment with the performance... it become more slower performance.

i use the command:
@QApplication::setGraphicsSystem("opengl");@

Did you try the hellogl_es sample? What device is this?

My device is Freescale IMX53 .
This example use the opengl functions for paint on the screen. I want to run a regular qt / qml application using the hardware acceleration of gpu and opengl.

I think this code snippet would be OK.
@ QGraphicsView view(&scene);
view.setViewport(new QGLWidget());
view.setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
view.setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
view.setViewportUpdateMode(QGraphicsView::FullViewportUpdate);
view.setFrameStyle(0);
view.showFullScreen();@
