Bug 496150

SUMMARY
On a multiscreen setup, starting to type the password before all windows are awake causes the focus to shift to another screen's password input. This leads to half the password being present on one screen's password input, and the other half being on another screen.

STEPS TO REPRODUCE
1. Lock your screen (Meta + L)
2. Press ESC to force your monitors to go to sleep
3. Wait for your monitors to go into "power saving mode"
4. Once the monitors are all asleep, start typing the password without waiting for monitors to be awake.

OBSERVED RESULT
As each monitor returns from sleep, the focus shifts to that monitor's password input.

EXPECTED RESULT
The password input in focus should always be the one on the main monitor, unless the user clicks on another monitor's password input.

ADDITIONAL INFORMATION
I personally don't see the need of having a password prompt on *every* monitor, but that's not the main issue. What really bugs me is the focus shifting around.

I've added a video of the bug in action [WARNING: some flashing lights].
