I am running Ubuntu 11.10, I found it is very power hungry, my notebook battery can last up to 3hrs. with previous version, but now barely enough for an hour. I installed a CPU scaling applet on previous version, which effectively scale down the clock rate, but I can't find similar app for this version, now when I put my hand next to the cool fan, I feel the burning heat from the notebook, it seems the CPU is running at full clock rate all the time !! I need an effective power saver, simple dim the screen is no use, and make it hard to read things, ok my battery is dying got to go...
Yeah, the previous version is better, and I can install an applet to control the clock rate, but now I've to look for other ways. Now I just 'go back' to Kubuntu, it has better widgets and there is one to control the CPU clock.
Thanks, but I keep updating everyday never stop, it is already kernel 3.x but didn't change thing, now I running Kubuntu and installed a CPU clock widget, I turn down it to powersave mode manually, the notebook now running cooler, but I still miss the old applet on Ubuntu that can control the clock rate on demand, this is the best way to do thing
Here is an alternative analysis of the power issue, but, be aware that the main disagreement with Phoronix is that it is argued that the use of the word regression (or, indeed, bug) in this situation is in error. So, you could say that this argument is mere semantics, but if the use of words leads you to the wrong actions...
The applets here and here might actually be of some use, but I have no idea whether either can be made to function with your distro, or to what extent they improve the situation. But if you do try, it would be worth posting back to keep us informed of your progress.
