Hi there, I'm trying to setup my xorg configuration on my dual graphic card desktop system. The system has two cards, one iGPU Intel HD Graphics 530, another is a dGPU Nvidia GTX 1070 on PCIe. I plugged one monitor to the iGPU port and another to the dGPU port and let the motherboard boot from iGPU. Right now, the fbcon works well on the iGPU, and I installed Nvidia non-free driver, and would like to run X on dGPU. I used the nvidia-xconfig to generate a Xorg configuration, and after starting Xorg, I got display from the monitor connected to dGPU, but it seems that the 3D rendering on that screen is software-based, and `glxinfo | grep vendor` showed that libglvnd on that X environment is selecting mesa as the GL library to use. With mesa being called on a dGPU connected screen, apparently it could not find a correct device to do dri, and fell back to software rendering. Does anyone know the proper way of config X so that libglvnd could know which GL library to use correctly in this case? Thanks, K.H.
