I started three VFb screens on my desktop and did 

export QWS_DISPLAY="Multi: QVFb:0 QVFb:1 QVFb:offset=20,0:2"

Now if I execute the program and try to show it on screen 1 or screen 2, I get to see it on all screens. Here is the code,

QDesktopWidget *d_widget;
d_widget = QApplication::desktop();
QWidget *w = d_widget->screen(1);
MyWidget widget(w);

regards
