Cpupower-gui is available on the official repositories for a few distributions.

Packaging status

Prebuilt binary packages for Arch, Debian/Rasbian, Fedora, and Ubuntu are available on openSUSE Build Service


Arch Linux and derivatives

Packages exist in AUR as cpupower-gui (cpupower-gui-git), built from this repo.

blackPanther OS

To install cpupower-gui run updating repos to update the repositories and install by running installing cpupower-gui.



To change the frequency settings, select the CPU from the drop-down menu, adjust the sliders and click Apply. Additionally, the cpu governor can be changed by selecting a governor from the drop-down menu. Last, to apply the same settings to all CPUs, toggle the All CPUs switch.

There are two governor profiles available, Performance and Balanced. The performance profile sets the governor for all CPUs to performance. Similarly, the balanced profile set the governor to either powersave (if available) or to a scalling governor such as ondemand or schedutil.

These profiles can be selected either from the desktop icon or the tray icon actions.

There is an option to enable or disable a specific cpu. This can be controlled via the the Online checkbox next to the CPU drop-down menu. Initially, the checkbox displays the state of the cpu, i.e. if it is online or offline.

Note: If this checkbox is greyed-out, it means that this cpu is not allowed to go offline.


The governor profiles can be used from the command line.

$ cpupower-gui -h

  cpupower-gui [OPTION…]

Help Options:
  -h, --help                 Show help options
  --help-all                 Show all help options
  --help-gapplication        Show GApplication options
  --help-gtk                 Show GTK+ Options

Application Options:
  -p, --performance          Change governor to performance
  -b, --balanced             Change governor to balanced
  --display=DISPLAY          X display to use

For example to switch all governors to performance run cpupower-gui -p. Alternatively, the application actions can be executed via gapplication.

# Switch to balanced profile
gapplication action org.rnd2.cpupower_gui Balanced

# Switch to performance profile
gapplication action org.rnd2.cpupower_gui Performance

Manual Installation

This package uses the Meson build system for build configuration and Ninja as the backend build system.

Clone the repository

git clone
cd cpupower-gui

Install build dependencies

The main build depencies are meson (>=0.50.0), ninja, glib2.0, and pkg-config.

To install them,

  • On Arch and derivatives: pacman -Sy pkg-config meson
  • On blackPanther OS and derivatives: (TBD)
  • On Debian and derivatives: apt update && apt install meson ninja-build, pkg-config, libglib2.0-bin, libglib2.0-dev
  • On Fedora: dnf install meson gettext pkg-config glib2-devel
  • On openSUSE Tumbleweed: zypper install meson gettext-tools

Optionally (for meson check) the following programs are needed: desktop-file-validate, appstream-util, glib-compile-schemas.

To install them,

  • On Arch and derivatives: pacman -Sy desktop-file-utils appstream-glib
  • On blackPanther OS and derivatives: (TBD)
  • On Debian and derivatives: apt update && apt install appstream-util desktop-file-utils
  • On openSUSE Tumbleweed: zypper install glib2-devel
