i’ve been playing with the render offload capabilities on these most recent drivers, following the documentation here
i have it working with manjaro using a patched xorg, by all accounts seems to be working as intended. xorg starts and shows the intel gpu as the rendering, im able to start both vulkan and opengl apps on the nvidia gpu using the launch variables, xrandr --listproviders shows both modesetting and nvidia.
where im uncertain is regarding power management, with this setup since the xorg process is running on the nvidia gpu there is no way to power it down short of killing the xorg process > unloading nvidia modules > and starting xorg entirely on the intel gpu exclusively.
is there no way to be able to run xorg on the intel gpu and use the nvidia to launch processes and offload to modesetting for display so that when the process (game, etc…) is ended, be able to unload the nvidia modulesto allow the nvidia gpu to power off.
am i wasting my time attempting to make this work?
do i understand correctly that getting the nvidia gpu to go into a low power state is the best possible outcome?
thank you for your time, i look forward to hearing back.
