hi pd1986

I think it depends on the compositor, if i remeber correctly it was working on wayfire (or mutter) and not in kwin.

Regards

I tried this some time ago with xorg and discussed the results here in the forum. Then experimented further with wayland. In my experience, dual gpu use is dependent on the linux distribution. Short answer: gentoo and debian can't do it.

If you find a solution I would be very pleased.
