Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I have Ubuntu Server 11.04 installed on an old noisy laptop. Its only purpose is to run subversion and I commit code quite rarely, but the laptop should work all the time.

So I would like to know how to turn on power management features for Ubuntu Server to enable automatic cpu scaling (reduce noise and heat) and make system power off display.
