It should be noted that setting the “low” profile (as suggested by “echo low | sudo tee /sys/class/drm/card0/device/power_profile”) is not guaranteed to actually work at all. There are a large number of cards which cannot drive a monitor correctly with the lowest clock settings. “medium” should be regarded as the lowest profile that's certain to work.
