If I understand it correctly, if the laptop is an Optimus one or has a mux, we are not "allowed" to opt-out of DynPwr/DynOff by powering down the card? In the same commit adding this conditional (5addcf0a5f0fadceba6bd562d0616a1c5d4c1a4d), you added the possibility to enable/disable dynpm. How is it supposed to work, by simply echo'ing ON or OFF to vga_switcheroo/switch? Then I probably forgot some stuff as it doesn't want to work on my laptop.
I can't remember to be honest
I think I wanted to stop the user from changing the state if it was dynamic, now if you turn off dynpm then you should probably enable that.
Dave.
