Thanks for reply. I have read your wiki before sent the email.
However, I am not quite understand how to do. Why it need to create  a
symbolic link of X servers but nothing to do with gdm? Moreover, I
don't have seperate keyboard & mouse attached for secondary
display(USB VGA) and therefore I just leave section of input device
empty for xorg.conf-sisusb.
