powermizer adaptive mode stays on max performance
nvidia-settings/PowerMizer shows that although the preferred mode is set to adaptive on my PC (with a GeForce 8600M GT card), the performance level/mode is always set to 2, ie maximum performance.
I can successfully use RegistryDwords in xorg.conf to force a lower performance level, eg I've done this for when on battery to save power (and 2d performance is fine), but when it's in adaptive mode it won't budge from high performance. It doesn't matter whether I run compiz or not.
Is this normal? Is there some setting I'm missing?
