Thanks for your inputs. How to start the multiple screens so that they are part of a Virtual desktop?

I started multiple screens by setting the QWS_DISPLAY env variable like this

export QWS_DISPLAY="Multi: QVFb:0 QVFb:1 QVFb:offset=20,0:2", Is that the write way for the example code to work? I think, it is not, cuase the mouse cursor is seen on all the screens.

What would be the alternate way to start the multiple screens?

regards
