Great! Thanks for the report > However, there is one issue. What version of upower are you guys using?

You might be able to take a page from the nvidia support hack in asus-switcheroo. If you load asus-switcheroo with the dummy-client=1 option, you don't need nouveau. Then you can echo ON/OFF to the vgaswitcheroo/switch file. I don't know if the power saving is as good as when the nouveau driver does it, but I can definitely tell a difference in watching the battery stats. If you don't need/want nouveau, you don't have to go through all the hassle of loading asus-switcheroo in the initramfs and making sure it gets loaded before nouveau. You can load it much later in init for that. > The problem is documented here and here (timing fits the timeframe for > 0.9.8) and consists on upowerd going berserk, sucking 100% of CPU, and it > happens with either the old or this new method. > version 0.9.7 works fine, though. > Since it happens with both methods, the problem should lie in upower.
