Ubuntu/Xubuntu/Kubuntu/Lubuntu Power Tests
Phoronix: Ubuntu/Xubuntu/Kubuntu/Lubuntu Power Tests
With the extensive Linux power consumption tests that I've been carrying out to solve some nasty Linux kernel power regressions and find other areas for optimization, one of the requests that has come in frequently is to compare the power consumption of the KDE, GNOME, Unity, Xfce, and LXDE desktops. After the article earlier this week to look at how the desktop environments / compositing window managers affect OpenGL performance, I carried out a quick desktop power test. In this article are battery power consumption results for Ubuntu, Kubuntu, Xubuntu, and Lubuntu.
Why is the wattage so high?
Having an unoptimized OS running idle sucking battery really bothers me, my laptop idles at ~7.2Watt with screen and wifi ON and it's not even a new model (only Core 2 Duo) So a normal 6 cell 4800mAh battery = 6 hours idle, 5 hours web for me.
Depends on the age of the battery, which I never see mentioned in the power consumption articles written out unto the Internet vast.
My Five year old Laptop began dying early in its third year.
Now in it's fifth year it barely maintains six minutes of computer activity.
Just saying it can be a false positive to point the finger at Linux sometimes.
The results look to be rather uniformed across the board. I'm surprised because I would have assumed Lubuntu would have been substantially great in its' ability to outperform its' brethren.
Another test would have been to utilize XBox Media Center (XBMC) and seen the power consumption performance during its' being run idle.
But I digress
I think they should start using KDE as the default, and create a Gubuntu for a Gnome-centric distro.
what does X axis is?
stretch it more in Y axis, to see differences
Nepomuk was indexing files and then stoped, so power usage droped to normal level?
