I have a very simple solution that solved it for me.

I have an Acer Nitro with NVIDIA GeForce GTX 1650. After installing Ubuntu 22.04, every time I attached an external monitor the Xorg CPU usage was 25% - 33% even when nothing is running. This happens with driver 470 and 510.

To fix it - run the NVidia X-server settings app. Under Prime Profiles, select
NVIDIA (Performance Mode).
Reboot. Now Xorg CPU usage is 0.3%.
