NVidia-185.18.14, Quadro NVS & Multi-monitor

Question

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.

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

Answer 1

I get the same error after replacing my VGA-cable. Maybe the cable (without those 'noise-cancelling magnets' on it) is hindering the EDID-data to be correctly detected...
