[panel] [multi-monitor] On secondary screen, unable to scrub from indicator menu to app menu

Reproduced this behavior on Precise in Unity as well.

I put nautilus on one display, and gedit on the other, both maximized. On the display with nautilus (the external monitor), using the mouse to navigate the various indicator menus works. Using the arrow keys to do the same likewise works. On the other display (the laptop lvds), mousing through the menus works, but when I use the left/right arrow keys I see an empty menu box pop up, which has arrows at the top and bottom and appears to be sized for content but no content is visible. Also it is positioned at the far top right corner of the screen rather than beneath its indicator.

Further experimentation shows it behaves like this even if all applications are shut down.

Booted into Unity-2d and reproduced it there, except the behavior is slightly different: The content of the menus *does* appear, but the menu is positioned at the laptop's top left corner (instead of top right).

Also, in unity-2d it appears you can only cursor left-wards. The right arrow key doesn't trigger menu navigation activity.

With unity 5.2, the behavior from comment #1 has changed. The arrow keys work to navigate the indicator menus on one screen, but on the other the menus display at the top left corner of the screen. (Same behavior in unity as was seen in unity2d from comment #2.)

This bug was fixed in the package unity-2d - 5.7.0-0ubuntu1
