G'day all, I still can't get powertop 2.0-beta to work properly, but the old 1.12 version does a good job of documenting those apps that cause most of the wakeups.
I keep firefox open with ~100 tabs most of the time, plus thunderbird and Zimbra desktop. Combined, this party is good for about 300 wakeups/s. I like to keep them open as I often refer to stuff while on a flight even if I can't get to the world, but they sit there chewing up battery like nobodys business. I use Gnome and I have 8 virtual desktops that I flick between, and I thought it might be an idea to send a -SIGSTOP to any apps on all but the current desktop. With the leverage of some already well written code (someone elses), I managed to knock up a little python script that automatically STOP's and CONT's anything running locally on the desktops as you switch between them. Significantly, over a 6 hour flight this averaged a watt of saving over what I saw on the way there. I can't be the first person to have done this, so I'll put the feelers out to see if anyone else has seen something similar?
