Title:
  Unity does not recognize twinview settings after crash and manual
  restart.

Bug description:
  I have a dual monitor setup with twinview. After Unity crashes and
  does not restart, I have to switch to a terminal and re-run Unity
  manually in order to interract with windows. Before I do this, windows
  maximize to only one monitor and I have a panel on both screens. (The
  top of my screens are not vertically aligned.) After restarting Unity,
  it treats the whole display as one big monitor. Windows maximize
  across both screens and there is only a panel on the first monitor
  (because it has disappeared off the top of the other one.)

  To reproduce:

  1. Do something that crashes Unity, such as 
https://bugs.launchpad.net/ubuntu/+source/nux/+bug/923567 (ie enable or disable 
the compiz window rules plugin)
  2. Repeat step 1 until Unity no longer automatically reloads. (might not be 
necessary)
  3. Switch to a console with ctrl-alt-f1 and log in.
  4. DISPLAY=:0 unity
  5. alt-f7 and maximize any window.
