Thanks!  This is the closest I've got so far, but it still isn't quite
right.

I can run `./nv-control-dpy --probe-dpys` and see the two devices:
Using NV-CONTROL extension 1.20 on :0.0
Connected Display Devices:
  DFP-0 (0x00010000): Seiko
  DFP-2 (0x00040000): DELL 2408WFP

but running set-associated-displays to 0x50000 just returns:
Using NV-CONTROL extension 1.20 on :0.0
Connected Display Devices:
  DFP-0 (0x00010000): Seiko
  DFP-2 (0x00040000): DELL 2408WFP

set the associated display device mask to 0x00050000

and "nothing" happens.  I can use any combination of 0x10000 and 0x40000
but it doesn't actually do anything to my displays.

The only way I got nv-control-dpy to do anything was to use
--dynamic-twinview and then xrandr to try and change to the new mode,
however it didn't quite work, leaving one screen black (except for the
cursor).  In the end I still had to run nvidia-settings to fix it...

I'm getting closer!  Maybe I should just look at the nvidia-settings
source...

Does anyone know if the nvnews forums are good with this kind of thing?

thanks,
