How does one force Plasma to use the iGPU in a system?

Title. Trying to get my Plasma install to not use my 1650 and instead use my HD 530, as I’ve been having issues with Waydroid and the only plausible fix is to force the DE to use the iGPU.

Is this a laptop with hybrid/optimus setup or is it a desktop?

Two things.

  • In a desktop, you need to plug the monitor into the motherboard and not the GPU if you want to use it.
  • Make sure the BIOS doesn’t disable the iGPU when an actual GPU is connected. That is pretty common.

Two things.
Main monitor is iGPU, secondary is dGPU. Don’t ask.
* iGPU is detected and sometimes used by Arch already.

Might be a little off topic, but have you set up PRIME to render with the dGPU when needed?

PRIME

This is what I used when I still had a NVidia GPU and only wanted to use the motherboard output.
