Hello.

> We have an NVIDIA Quadro NVS 290 graphics adapter.

We use NVIDIA Quadro NVS 400 / 440 for quad-view setups:

I'm not sure that NVS290 can do this ?
(according to: http://www.nvidia.com/page/quadronvs.html:
NVS440 - Max Displays/Board = 4
NVS290 - Max Displays/Board = 2 ...)

We use 96.43.01 nvidia driver at present (but 87 series worked too,
with slightly different xorg configs, with "UseDisplayDevice" option
AFAIR ..).

Frankly saying I never got too much luck with nvidia's own
config tool , therefore I always did it manually ;-);

You may need to change the following:

- BusID lines in Device sections
  (you may see these on your system using /sbin/lspci)

- ConnectedMonitor in Device sections
  (ie if you use DVI connected LCDs that would be "DFP,DFP"
   rather than "CRT,CRT")

The config we use for 4 outputs is as follows:
