Public bug reported:
Resubmitting this bug because it seems to have disappeared from this
site?
I was asked to find out if nvidia-settings detects the monitors properly
and it doesn't.
The original bug I submitted was as follows:
This is my xorg.conf file

At the moment, if I chose Unity3D, it will just display on 1 screen, if
I choose Unity2D it will mirror 1 screen to all screens, so I have to
resort to gnome-classic to get all 4 screens to work with the above
xorg.conf.
