Trayfreq (pronounced tray-freek) 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
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
[battery]– the group battery
show=1– 1 to show the battery tray icon, 0 to not show it
governor=powersave– this sets the governor to use if the battery is discharging
[ac]– the group for if the batter is not discharging
governor=ondemand– this sets the governor to use if the battery is not discharging
[events]– the group events
activate=/usr/bin/xterm– this sets the program to launch when the tray icon is activated (left clicked usually)
[governor]– the group governor
default=ondemand– this sets the default governor to be set when trayfreq starts
[frequency]– the group frequency
default=800000– this sets the default frequency in hertz to be set when trayfreq starts
Note that, if a default frequency is set, it will override the governor.
[battery] show=1 governor=powersave [ac] governor=ondemand [events] activate=/usr/bin/showbatt [governor] default=ondemand #[frequency] #default=800000
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
~/.trayfreq.config; if it exists, trayfreq will not look at
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.
