Dear Maintainer,

On Asus Zenbook pro laptop with Nvidia and Intel 630 GPUs, not using NVIDIA
prop. driver, switching
to external display only (LG 27" 4K display) the system becomes super sluggish,
3-4 sec. on average to respond to any interaction (keyboard or mouse clicks).
Using "join" or "mirror" option fixes the issue, however I don't like the
laptop display on, waste of energy.
Ths is under Gnome Xorg, when login in using Gnome wayland both displays show
black screen.
