Indicator CPUfreq

Yet another very useful Gnome applet got an Ubuntu indicator applet (AppIndicator): CPU frequency scaling applet. By using an appindicator, this tiny application will be able to run in Ubuntu 11.04 without using a Gnome panel (the Unity panel doesn't support the regular Gnome applets).

For now it still depends on gnome-applets, but this might change in the future.

It's nice to see that most applets are getting an indicator and will thus work on future Ubuntu versions, but it's a shame for all the good applets that will be lost in this transition. And it's not just Ubuntu - Gnome Shell won't support all these applets either.

Install Indicator Cpufreq in Ubuntu

Add the PPA and install Indicator-Cpufreq in Ubuntu by using the following commands:
sudo add-apt-repository ppa:artfwo/ppa
sudo apt-get update
sudo apt-get install indicator-cpufreq

Then to run it, press ALT + F2 and enter: "indicator-cpufreq" (without the quotes).

Indicator Cpufreq is very new so you may find bugs - report them @ Launchpad!
