I am using a secondary monitor connected to my laptop's VGA output.
However, many app popup dialogs, including Ubuntu's display settings show up on that secondary monitor. This is very annoying because I use it for display and I cannot easily see that monitor when working.
I have Unity menus on the laptop, which is supposed to be my primary. How can I enforce all new windows and monitor settings also show up on primary monitor?
I edited monitors.xml and added primary = yes to all displays which looked like laptop screens (for some reason I have several configurations there). Logged out and back in - same problem. See monitors.xml at http://pastebin.com/zJgstAbf
