I noticed that when you have an external monitor wired to the NVidia chip on an Optimus laptop, it doesn’t work unless you configure Xorg to use NVidia exclusively. Is there any chance to be able to use PRIME while having both the laptop monitor and the external monitor working?
You’re probably talking of render offload. The answer for that is no, not possible…
Any chance for it to ever be implemented?
Yes, it’s the output sink feature that’s missing, nvidia devs are looking into implementing it. Don’t hold your breath, though.
