How to get multiple displays working with docking station?

Solution 1:

This affected me too. Finally after weeks of frustration I found the solution posted in a Launchpad bug (https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1382462).

In short:

  1. Install CCSM (sudo apt-get install compizconfig-settings-manager)
  2. In CCSM go to "General Options" --> "Display Settings" and do the following:

    • Un-check "Detect Outputs"
    • In the Outputs array, set the resolutions of each of your screens.

      In my case it was:

      1920x1080+0+0

      1920x1080+1920+0

  3. Now edit your display configuration as usual. In Unity: Dash --> Screen Display
