How To Control CPU Speed of your Atom-powered ASUS EEE PC in Ubuntu Linux
Since the release of Ubuntu 9.04 Linux for netbooks, I have finally started using Linux more than I used to. However, there was one thing that I found that was missing from the Ubuntu that ASUS offered for Windows XP: Super Hybrid Engine (SHE). This allowed you to downscale the speed of the processor which played an active part in improving the battery life. Unfortunately, ASUS never made SHE available for the Linux OS. Luckily, Grigori of geekmind.org has made a utility known as eee-control that lets you downscale as-well-as upscale the CPU speed as per your requirement.
eee-control is an easy-to-use utility for controlling Eee PC hardware under Linux. It can toggle hardware (WiFi, Bluetooth, etc.) on and off, lets you configure all hardware hotkeys, enables aggressive powersaving, and more.
Now, when I am on AC-power, I use my EEE 1000H in performance mode and when I am mobile, I use it under powersave mode to prolong the battery life. Earlier, I used to get 3.5-4 hours in Linux and now, I am able to get 5 hours in Ubuntu Linux, which is pretty respectable for a netbook.
The eee-control automatically starts when you log-in and resides in the taskbar so that you always have access to it when needed.
PS: Regarding the above screenshot, it is Ubuntu 9.04 with Mac theme

Nice tip there Kamal! Now, I can finally put ubuntu in my eee 901.
It works fine on my 1000HE. :)
I assume it should work with 1101HA as well, right?
I do not have that netbook, but there is no harm in testing
using Ubuntu 9.10 on 1000H, works but do not have “Super” performance option.
