Scaling CPU in Ubuntu Natty

When I use my laptop in Ubuntu Natty I notice extra heat from the CPU. It seems like Windows is being more agressive at slowing the CPU down to save power. Unfortunately, the Power Management control in Natty doesn’t mention CPU speed at all.

There is (or was?) an option for controlling the CPU in the Power Management control. But I wasn’t able to get it to work.

Instead I installed the cpufreq indicator:

$ sudo add-apt-repository ppa:artfwo/ppa
$ sudo apt-get update
$ sudo apt-get install indicator-cpufreq
$ indicator-cpufreq&
