    So it’s possible to have two different GPUs rendering content which is then output to a single monitor at the same time? Could I have a game rendered by a discrete GPU running in a window being handled by an Xorg session rendered by an integrated GPU? Do I understand this correctly? Would it matter if the video output was physically connected to the discrete GPU or the motherboard, or is that configurable?

      I used to do this, but I use wayland now. Similar setup though.

      Yes it matters. On many laptops the hdmi out is ONLY on the discrete gpu, meaning the discrete gpu must be on (and sucking power) in order to display to external monitors, even if the internal gpu is doing the rendering.

      While I’ve not tried this yet, and won’t eb able for a while it does sound like this would be possible. Quite the cool tech. Not sure about your last part of your question unfortunately. Probs best to follow their forums for this.
