GFreqlet is a Linux software that helps users monitor CPU frequency scaling, and adjust related power management settings via a gnome applet with easy-to-use features.
The applet itself is not run as root and does not require modification to run with root ownership. However, it does prompt for passwords with gksudo if a super user action is required. As open source software, licensed under the GNU GPL (General Public License), there's no doubt that GFreqlet is a reliable and trustworthy applet.
To use GFreqlet, you'll need a modern processor that supports CPU frequency scaling, and a Linux kernel 2.6.x compiled with CPU frequency scaling, procfs, and sysfs support. Additionally, you'll need the GNOME Desktop, GNOME applets, the Python programming language, GTK+ bindings for Python, Python bindings for the gnome desktop environment (python-gnome-desktop in Ubuntu), cpufreq-selector, and gksudo.
What's even better about GFreqlet is the new release with support for Power Management (ACPI) on notebook systems. New preferences for default frequency scaling on AC and battery power make it even easier for users to manage their CPU frequency scaling. So if you want an applet that's easy to use and reliable, GFreqlet is the way to go.
