Cannot get 3D Vision 2 to work...

Also from NVIDIA regarding the legacy driver:

We plan to also fix this in the legacy 340* driver but that will take more time and unfortunately currently there is no schedule.

Hello Guys,
did you actually manage to get the stereo to work correctly under linux?
I experience problems with a partially working stereo which does not function on the lower quarter of the screen.
There is a thread on this subject here:
https://devtalk.nvidia.com/default/topic/963902/cannot-get-3d-vision-2-to-work-/?offset=14#4986531.
Any ideas are welcome how to overcome this problem and it would be nice to know whether this problem is experienced more widely.
Best
Wim
