NAME

cpupower-gui - Set the scaling frequencies and governor of a CPU

SYNOPSIS

cpupower-gui

DESCRIPTION

This manual page documents briefly the cpupower-gui command.

cpupower-gui is a graphical (GUI) utility to change the CPU frequency.
This utility can change the operating frequency of the CPU for each core separately. Additionally, the cpu governor can be changed. The program can detect offline cores and only present the available ones. Furthermore, if a core doesn't support frequency scaling, is not shown. There is also an option to apply the same settings to all cores simultaneously.
To apply the settings, the user must be local and active, as well as in group sudo. Local and active users not in this group must authenticate themselves as admin in order to apply the settings.

The cpupower-gui program can be configured using the configuration file in /etc/cpupower_gui.conf. Files that are stored in /etc/cpupower_gui.d/ take precedence over the main configuration file. The files are read in a lexicographic order and the last files override the first.
Apart from the main configuration users can store their customisations under ~/.config/cpupower_gui/. Files read from this location will override the system configuration.

Custom frequency settings are stored in *.profile files and user can use them to quickly apply their preferred settings. These files are simple text files where the first line contains the name that the profile will be known as and the rest of the file contains CPU settings in a table-like format.An example profile file is located at /etc/cpupower_gui.d/my_profile.profile.ex.

On some platforms there is the ability to change the energy performance preferences. These feature is available on Intel systems that use the intel_pstate driver.
