ok, I remember someone told me it'll just magically work. I found "Optimus" yesterday, but that seems only support GF serial.I'm currently use VNC + headless NV on linux, learn from VirtualGL | Documentation / Headless nVidia Mini How-To

Technically the igd-assign document and the idea of UPT is specific to Intel IGD, but Quadro cards work similarly to UPT mode. IME only Windows 10 will take advantage of the assigned GPU to render into the emulated graphics, but performance will take a large hit. Thanks, Alex
