Bug Description

I'm using 5.0.0~+bzr1824ubuntu0+611 from the unity-team ppa. I had it working on my laptop and then I plugged in a larger external screen. The left-side panel is still only the size of my original laptop screen, rather than resizing to fill the whole screen.

=====Steps=====
the duplicate bug report had mentioned a few steps to reproduce the problem

1 connect a 24" LCD to laptop
2 turn off internal LCD panel with DIsplays, then only external LCD will be used
3 the length of launcher is supposed to be expanded accordingly, in this case, it should be expanded to 1080pixel, but it doesn't

From one of the duplicate bugs:

"""
For Oneiric:

It looks like this bug depends on the state of the monitor during switching, i.e. it occurs when the monitor is off/on some powersafe-settings.

Steps to reproduce:
1) Turn off the external monitor
2) Go to the Monitor-config in ubuntu and disable the laptops screen and enable the external monitor (at the same time)
3) Press 'apply'
4) Switch the external monitor on
5) Observe bug
"""

When I follow these steps with an external monitor configured to the left of the laptop, the launcher bar is the correct height, but I see a second launcher bar to the right about 3/5ths of the screen width. See attached photo.

I also note the extraneous launcher also has pointer barrier action going on. Funky.

having just hit the variant of this bug 933942, I can promise you the monitor was not off or powersaved per se. it may have been transiently offline while the screens were rearranged.
