CPUPower-GUI is a simple graphical utility allows to change the frequency limits of your cpu and its governor.
With the tool, you can easily change the frequency settings based on CPU core by adjusting the sliders and clicking apply button.
You can also change the cpu governor profiles, Performance and Balanced. And the profiles can be selected easily from the system tray indicator menu.
The software also offers an option to enable or disable a specific cpu via the online checkbox. If this checkbox is greyed-out, it means that this cpu is not allowed to go offline.
How to Install cpupower-gui in Ubuntu:
The software is available in Ubuntu universe repositories since Ubuntu 20.04. The package however is always old.
To get the most recent packages, go to opensuse build service page.
Download and install the .deb package either via Gdebi package installer or by running apt command in terminal:
sudo apt install ./Downloads/cpupower-gui*.deb
For the source tarball and more about the utility, go to github project page.
Doesn’t work on Ubuntu 20.10:
Traceback (most recent call last):
File “/usr/bin/cpupower-gui”, line 367, in

Unfortunately same on Mint
latest mint works with this version
https://silvae86.github.io/2020/06/13/switching-to-acpi-power/
however the icon on the bottom right hand corner does not work at all but the cpupower-gui from the start menu does work and it seems to be an older version than the one supplied here but it works!
so i removed the startup entry for the icon from at bottom right hand corner and just use the cpupower-gui from the start menu.
also i did not go past the entry below to install the startup applet as suggested in the link above but the applet installs itself irregardless.
FROM THE SITE ABOVE…
First, you need a way to see your actual CPU speed to see if any of these changes work.
watch grep \”cpu MHz\” /proc/cpuinfo
Changing to acpi-cpufreq CPU management driver
sudo apt-get update
sudo apt-get install acpi-support acpid acpi
The idea here is to replace the intel-pstate CPU power management driver with the acpi-cpufreq one. This allows for better performance and slightly more efficient power use in some cases, as shown here.
Disable intel-pstate in grub config
To disable the default intel-pstate driver, you need to
sudoedit /etc/default/grub
and add
GRUB_CMDLINE_LINUX_DEFAULT=”i8042.reset quiet nosplash debug intel_pstate=disable”
After making our edits, we need to refresh grub:
sudo update-grub
cpufrequtils tool family
sudo apt-get install cpufreqd cpufrequtils indicator-cpufreq
sudo apt-get install -y linux-tools-$(uname -r)
# GUI for editing cpu power configs
sudo apt-get install cpupower-gui
so i went no further than that command but that gets an older working cpupower-gui!
