Plasma-shell loads to dGPU by default

General

My plasma-shell loads to dGPU (NVIDIA), not iGPU (Intel) no matter what i do. Is it possible to correct it?

Step 1 (mostly success)

  1. go to bios
  2. change your prefered GPU to iGPU first, instead dGPU
  3. boot normally

Step 2 (if step 1 is failed / no access / no option on bios)

  1. check your card path with lspci -v | grep -A 10 -i "vga"
  2. create a override environtment variable in .config/environment.d/99-gpu-primary.conf (adjust the priority with your card, on my example, i prioritize the card1 instead card0)
KWIN_DRM_DEVICES="/dev/dri/card1:/dev/dri/card0"
KWIN_DRM_NO_AMS=1
  1. reboot
