I managed to get my dGPU to run in D3cold state in my hybrid graphics laptop (RTX 4060 + Intel UHD). I could verify it with cat /sys/class/drm/card*/device/power_state. However, as soon as wayfire run, it uses both my GPUs for some reason and the power states are stuck at D0 for both. Can wayfire be configured to exclusively use iGPU only (so that I can save power on my laptop)? This is the result of nvtop with wayfire running

You can try setting WLR_RENDER_DRM_DEVICE=/dev/dri/renderD# and WLR_DRM_DEVICES=/dev/dri/card# before starting wayfire? (where the number # is specific to your device)

I have pretty much the same setup and @soreau's suggestion is exactly what I do:

WLR_DRM_DEVICES=/dev/dri/card0 WLR_RENDER_DRM_DEVICE=/dev/dri/renderD128 wayfire

Just make sure to replace D128 and card0 with the numbers corresponding to the iGPU.
