Bug 478696

SUMMARY
Currently the Switch Display popup is only shown on the screen where the mouse (or active window?) currently is. However, if this use can no longer see this screen (e.g. the connected to a monitor which switched to a different input source) it becomes hard to disable that output. The user has to blindly navigate the mouse back to a visible screen in these cases.
Instead, we could simply show the popup on every connected screen and allow cycling through the available modes by pressing the keyboard shortcut again (similar to the task switcher). Other OS are already using this technique.


STEPS TO REPRODUCE
1. Have two screens connected to you machine.
2. Press the "Switch Desktop" shortcut (likely Meta+P, or a function key).
3. Press the same shortcut again

OBSERVED RESULT
The popup is only shown on a single screen and pressing the same shortcut again does not rotate through the available options.

EXPECTED RESULT
The popup should be shown on every connected screen. Pressing the same shortcut again should also rotate through the options similar to how Alt+Tab works with the task switcher.
