I haven't tried turning off dynamic power management during boot time. Just in case I edit that line, does that mean that I would have to start DPM manually if I want to use discrete GPU?
dynpm != dpm. dynpm controls whether the dGPU is powered down when not in use or not. dpm dynamically adjusts the clocks on the GPU based on load.
