Ubuntu's Power Consumption Tested

Posted by kdawson on from the no-lyme-disease dept.

RedDragon writes "Ubuntu 7.10 is due out on Thursday, October 18, and in addition to desktop 3D effects, GNOME 2.20, and other features is the use of the Linux 2.6.22 kernel with the tick-less (CONFIG_NO_HZ) kernel feature. But does this mean enhanced power savings when compared to past Ubuntu releases? Phoronix tested Ubuntu power consumption looking back 2-1/2 years at the six Ubuntu releases from Ubuntu 5.04 to the yet-to-be-released Ubuntu 7.10. Testing was done when the system was idling and then under load, and when the Lenovo notebook was powered via the battery and then again with the AC adapter. The Pentium M CPU temperature was also monitored. While Ubuntu 7.10 does include the tick-less kernel feature, more daemons and processes running by default on these modern Ubuntu releases is actually causing an increase in power consumption."

    Me too, but I'd need to be able actually read the article with Safari on OS/X first.

    1. Run the particular distro.
    2. Make sure the power cord is long and in the open.
    3. Allow a penguin to chew through the cord.
    4. Measure the distance the penguin flies after chewing into the cord. This will give you some idea of the power usage.
    5. Well, don't let that penguin go to waste! BBQ and teriyaki are great ways to make penguin. Personally, I prefer General Tso's Penguin myself.

    Scary for me -- CDs auto unmount when you press the eject button. When did that happen? Worried I'll start getting BSODs next ...

    I think you mean 3d acceleration. 3d accelerometers measure tilt and motion in three dimensions. I think you mean thrii diimensions. But Wii forgive you.
