nVidia-185.18.14, Quadro NVS & Multi-monitor

For anyone who recently upgraded their drivers to 185.18.14, you may have this
problem where your secondary monitor refuses to work anymore.

This is especially so if :
-  your graphics card is one of those Quadro types
-  it has one of those special card-output (video-cable connectors) where one
   single DVI connector splits into two separate VGA ones.
   
This might also affect laptops with a VGA port to output to a secondary screen.

Long story short, put this in your [xorg.conf] file, under the Device section :

Option         "ConnectedMonitor" "CRT-0, CRT-1"

So it'll look something like this :

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "Quadro NVS 290"
    Option         "ConnectedMonitor" "CRT-0, CRT-1"
EndSection

That basically forces the card/driver/gremlins to detect your second monitor
as a CRT, not a DFP (digital flat-panel). If you're connecting both screens via
normal 15-pin VGA cables, they're both CRT connections, not a DFP.

I sourced this from a Debian user's posting :

Hopefully, this will solve your problem as it did mine.
