Comment 9 for bug 661450

Funnnny: what happens if you logout and back in after adding the second monitor?

For me, I had setup my 2nd monitor in a classic session, with my 1920x1200 external monitor to the left of my laptop's 1400x1050 monitor (aligned at the top). I then logged into a unity session, and saw the unity interface on my laptop monitor. However, interacting with the interface showed the pop ups over on the far left, and moving windows made the launcher vanish not when a window was near the launcher, but when it was near the left side of the left screen. I'll attach a screenshot of this as ext-left.png. I have the application menu open, showing (1) its bad position, and (2) that it is blank (I have to mouse over items in the menu to make them appear).

I then use the monitor app to position my external monitor to the right of the laptop screen. The unity interface does not move to its proper position at 0,0, and instead stays way over to the right, drawn in its original size and position relative to the original 0,0. I'm attaching this as ext-right.png.

I then logout and log back in. At this point, unity is sitting at the normal 0,0 position, and behaves reasonably well, though the blankness in the applications menu persists.
