Not aware of it; only the use of a window.  But I'm wondering about the 
NVCtrl thing.  libXNVctrl is installed but "not available on screen ''", 
and I just added nvidia-settings, but no difference seen.  I think 
that's where the other box finds the precision rates, and maybe audio 
uses one and video, deep in the works, another.
