Display a panel in both screens in GNOME-Classic

view full story

http://askubuntu.com – I am using Ubuntu 12.10 with GNOME-Classic (I got tired of Unity). I use 2 screens, and by default, there is only 1 panel at the top of the the first screen. I can Add a panel to my second screen, but it is empty. I need to add each element of the first one to the second one. How can I display this panel on both screens, or at least, how to duplicate the first panel to my second screen ? (HowTos)
