In Ubuntu 10.10, I added the CPU scaling applet on my panel in order to control the CPU frequency scaling. Since Unity no longer has a panel that supports applets, what mechanism do I use in 11.04 to achieve the same goal?
you can also create a launcher. Right click on desktop, select "create launcher" name it, icon it, and put "indicator-cpufreq" as the command. then drag it to the unity launcher. I have a folder in home which keeps my desktop free of launcher clutter while the applet war wraps up.
