I may not be technically correct, but I would assume that the nVidia
tool does not change brightness of the display, but does change the
settings of vcgt of the graphics card - most probably just gamma. Then,
argyllcms wants to calibrate the display using changes in the graphics
card, too, which overrides what nVidia tool originally set. This is
probably an expected behaviour.
What you should aim for, is first calibrate your lcd using hardware
knobs (I doubt there are any apart from backligt brightness on the
notebook), then let argyllcms do some further calibration using changes
in the video card.
I.e., do not do any adjustments in the nVidia tool.
