Bug#789392: general: fails to show dual screens on startup

[Carlos Cunarro <carloscunarro@gmail.com>]

Package: general
Severity: normal

Dear Maintainer,

   * What led up to the situation?

The problem I am having is that when I turn on my laptop with the hdmi cable
connected to another screen, the laptop screen seems like "turned off".

Laptop (Screen 1) + Samsung Screen 22" (Screen 2).

The same problem happens if I logout (my laptop screen "turns off").


   * What exactly did you do (or not do) that was effective (or
     ineffective)?

To solve this I have to go to display settings and start playing with the
configuration 2 o 3 times until I can see my laptop screen working.


   * What outcome did you expect instead?

The outcome expected is being able to turn on my laptop connected with the hdmi
to another screen and see both screens fine. Screen 1 on the left and Screen 2
on the right, both visibles.
