I am using xubuntu 13.04 with a dualmonitor setup. (external monitor as primary, laptop als secondary) I am using xandr to makeup my monitorsetup. However I recognized that the xubuntu panel on the top by default will always be placed on the laptop monitor. I know that i can move the panel via the panel preferences. This works. But i want to somehow either let it move automatically to the right monitor (the primary one) or to move it with a terminal command (so i can create a script which takes care of moving the panel to the primary monitor)... any ideas?
