New powertop is nice, but it seems to have lost my favourite feature which was the reading of current power consumption in Watts. Is there a good reason why that is no longer printed?
Currently I can twiddle params between 'good' and 'bad', and I can see how that changes the fraction of time in various states, but not the _actual power consumption_ which is what I am trying to optimise.
I can sort of guess by wiating a while and looking at the 'time left' pop-up in xfce4-power-manager, but that's still not actual current average consumption, although I naively hope it's linearly related to it.
And more help on the what the various params actually _do_ would be really nice. For the non kernel-power-management guru most of it is highly cryptic. Some idea of each tradeoff and associated risks would be very nice.
In practice I've found that turning everything to 'good' still leaves my machine working, and this article has allowed me to discover there there is an easy way to put all that lot in my 'onbatt' script, which is great. Some of them should perhaps be on for mains use too though - and I have no idea how to work out which.
