* Having ethernet plugged in (e1000e) makes it only get to pc2
* Having the discrete gpu powered off with bbswitch while xorg starts freezes the machine
* Having the discrete bpu powered off with bbswitch while loading the proprietary nvidia driver freezes the machine
* nouveau seems to freeze the machine no matter what bbswitch state
* Using bbswitch to power off the gpu it only gets pc3, loading the proprietary nvidia driver instead causes it to get into a lower pc-state (pc8? iirc), but more total power usage
* switching the powertop tunable "Runtime PM for PCI Device NVIDIA Corporation GM107GLM [Quadro M1000M]" makes the nvidia driver fail to load until next reboot (even if you switch it back)
