High CPU usage on xorg when the external monitor is plugged in

Hi,

I would like to share my “workaround”

lets go:
my bios is mshybrid (nvidia optimus)
prime-select on-demand

I inserted into 70-uaccess.rules (udev), affet this line # DRI video devices

  • SUBSYSTEM==“drm”, KERNEL==“fb0”, TAG+=“uaccess” ← avoid built-in monitor glitches when nvidia is set primary_gpu

10-nvidia.conf

  • Option ""PrimaryGPU “Yes”

It is not final solution but i believe it can contribute some with this issue …

Thank you

Luiz
