Yes, that’s a good point, I think the thunderbolt out only works on the iGPU, so I’m assuming that to get dual external monitors (HDMI and usb-c) the bare metal OS (Linux) will have to be running at least the iGPU.
I guess that also begs the question: X or Wayland in this scenario?
Great info, thanks! That makes two mentions of Pop_OS so I guess I’ll give that a try first.
