Using Ubuntu 12.10 with GNOME 3.6
I have plugged in a second monitor to my laptop and can drag windows between. I am using Compiz to handle virtual desktops and have switched that to scroll desktops at the same time.
How can I show the taskbar on both monitors, and only the windows on that monitor show on that taskbar?
For bonus points can I set it so that when I plug in my number of desktops decreases - I no longer need to have 2x horizontally, just vertically. If I unplug I'd like the second screen to switch to desktops 2 and 4 respectively.
