NVidia GT 640 (Kepler) on new Dell Inspiron Models

[Dreamwatcher]

i made DSDT include graphics-injection or GrapchisEnabler =yes , so black screen.

i tried no graphics-inject and GraphicsEnabler=no, full worked with QE/CI.

GK107 is worked by default setting (NO DSDT , DSDT no gracpcs-inject or GraphicsEnabler=no).
