tl;dr: Enable DRM for all graphics output and retire fbdev drivers in TW.
Quoting Alex Deucher regarding relatively high idle power consumption of GPUs on Linux vs Windows:
"That explains it. Windows is able to power off the dGPU when it's not in use, but in Linux, due to the limitations of the framebuffer console, we can't power down the primary GPU right now when the console is bound to it. As a workaround, you can unbind console from the fb or disable the drm fbdev emulation in your kernel config."

I'm wondering if going full DRM will help solve this issue?
No, not yet. I'm sorry. Replacing the current fb console by something modern is another big project for next year. At least a fully DRM'd graphics stack is a step in this direction. Best regards Thomas
