Restarting Gnome Shell

Different ways to restart or re-log current Gnome Shell session

  • user’s Log-out / Log-in (X11/Wayland)
  • Alt+F2 and enter r command (X11 only)
  • or just reboot PC (X11/Wayland)


Managing Extensions

Here are some ways to manipulate the extension state (enabling, disabling, installing, updating, removing settings...).

You can manage your extensions in many ways:

  • gnome-shell-extension-prefs
  • web browser page Installed Extensions
  • gnome-tweak-tool
  • Gnome Software Center.
  • Manual method by removing any extension folder you will remove the extension. After this operation you have to restart current Gnome session.


Finishing the installation

After installing/updating the extension on the system, you have to finalize the procedure in order to allow it to manage the system's power settings

A couple ways to do so:

  • In the extension menu Select ⚠ Install… or ⚠ Install Updates… menu item.
  • In the terminal Run install command
    sudo ~/.local/share/gnome-shell/extensions/cpufreq@konkor/cpufreqctl install


Upgrading the extension

Here are some ways to upgrade the extension

Hopefuly frequently, the extension will receives updates to fix bugs, update the documentation or add new features and abilities. So here is a few ways to do this:

  1. You can update the extension through the web browser page Installed Extensions
  2. You can do this in the Gnome Software Center.
  3. You can get the development version from GitHub.
    • Download desired archive from GitHub
    • Extract
    • Replace all files in the ~/.local/share/gnome-shell/extensions/cpufreq@konkor folder.
    • Restart GNOME Shell.
  4. You can use installation script to do it. Using the command will switch you to the latest desired GitHub branch:

    After Upgrading you may have to finish the installation as the extension could also update its API.



Sometimes we need to remove some extension. The cause could be for example complete reinstallation or bugs. It can be useful if you have saved broken settings values or to clean up previous installations.

Completly removing the extension and stored settings.

  1. Remove the extension folder
    rm -Rf ~/.local/share/gnome-shell/extensions/cpufreq@konkor

    Be careful with this command as any mistake could cause a data loss!!!

  2. You can check this values in the dconf-editor at /org/gnome/shell/extensions/cpufreq/
    dconf reset -f "/org/gnome/shell/extensions/cpufreq/"
    sudo rm /usr/share/polkit-1/actions/konkor.cpufreq.policy
    sudo rm /usr/bin/cpufreqctl

    If you want reset the extension’s values to defaults just run it and restart gnome-shell.

    dconf reset -f "/org/gnome/shell/extensions/cpufreq/"



Missing symbols

If you have missing symbols you are, probably, missing some fonts, try to install TTF Freefonts, DejaVu or/and Droid font packages to fix it.

Gathering information for reports

Provide more information about your hardware and system like:

  • Intel or AMD CPU
  • intel_pstate or acpi_cpufreq CPU driver
  • Kernel version
  • IRQ Balance enabled or disabled
  • Are you using CPU powering off/on in your profiles
  • Include system journal log’s messages or just related parts. See more about logs below.

Report to issues with included system information like distributions, CPU, acpi-cpufreq/intel_pstate mode, system journal errors and description of the issue.


  1. First thing to do is check your clean desktop environment to do so you should disable all Gnome shell extensions including this one. Some distributions including pre-installed many extensions and they could conflict with new updates or each other. If all looking fine you can go to the next step.

  2. Enable only this extension to test it and easy check system messages. You can check the system journal messages in a terminal.

  3. Run the command sudo journalctl -f in a terminal to see real-time system messages monitoring and restart Gnome Shell (X11 only): Alt+F2 and enter r command.

sudo journalctl -f
  • Do not close the monitor in a terminal. Open the extension menu and try to change profiles and/or other settings. You could see maybe some warnings, errors or when it locks. Copy/paste related messages to text file and include it in your report.

  • Alternatively, you can just grep all messages and check for errors and other warnings.

# For cpufreq messages
sudo journalctl |grep cpufreq

# For all gnome-session messages
sudo journalctl |grep gnome-session
