Trayfreq (pronounced trayfreek) is a GTK+ application released under GPL that lets you select your CPU's governor or frequency from a tray icon and displays information for your battery. Trayfreq is designed to be desktop-environment-independent so it depends only on GTK+ and a system tray to show its icons. Trayfreq is the perfect addition to Xfce, LXDE, and Window Managers (Openbox, Fluxbox, etc.).


  • Displays a icon that shows you the relative current CPU frequency
  • When the CPU icon is right-clicked, it provides a menu of available frequencies and governors to choose.
  • When the CPU icon is left-clicked, it runs a command (set in config file, default nothing)
  • Displays a icon that shows you the status of your Battery (Charging, Discharging, Charged) and its relative current charge (optional)
  • Toggling of CPU governor based on if the battery is discharging or not.
  • Lightweight, Desktop-Environment Independent

Latest Version



Install trayfreq from the AUR. I suggest using one of the AUR Helpers.

System Setup

CPU scaling requires you to have a kernel with the ability already built in or have an appropriate driver module loaded. If the former case represents you, then you do not have to worry. If the latter case represents you, follow the following steps:

Most modern computers use the module acpi-cpufreq. Other options include the p4-clockmod, powernow-k6, powernow-k7, powernow-k8, and speedstep-centrino drivers.

To load the driver, modprobe it:

# modprobe acpi-cpufreq

To load the driver automatically at start up, add the module to Template:Filename:

# MODULES=( ... acpi-cpufreq ... )

CPU Governors Setup

Some CPU governors may not be built into your kernel, but you can add them to Template:Filename to have them automatically load at start up. Again, edit Template:Filename to load the governors' drivers.

# MODULES=( ... cpufreq-powersave cpufreq-userspace cpufreq-ondemand ... )

Trayfreq Setup

Now, let's edit the configuration file for trayfreq.

$ cp /usr/share/trayfreq/trayfreq.config ~/.trayfreq.config
$ nano ~/.trayfreq.config

Everything will be commented out; uncomment what you want to use. Let's go through the options

Note that, if a default frequency is set, it will override the governor.

Sample File:


If you want, you can have a configuration file in your home folder, but it can now set the program to run when the tray icon is activated too. The file should be Template:Filename; if it exists, trayfreq will not look at Template:Filename.


A desktop file is installed into /etc/xdg/autostart/. It will automatically start once installed. If you do not want it to start automatically, open the start up manager that comes with your desktop enviroment and uncheck trayfreq.
