Configure Logitech or SteelSeries Headset in Ubuntu via This App

Last updated: March 21, 2023 — Leave a comment

Got a Logitech or SteelSeries headset? This app may help to adjust sidetone, get battery state, toggle LED, and set inactive time in Ubuntu Linux.

It’s HeadsetControl, a free and open-source application that supports:

  • Logitech G430, G432, G433, G533, G535, G633, G635, G733, G930, G933, G935, G Pro.
  • Logitech Zone Wired/Zone 750
  • SteelSeries Arctis 1, Arctis 1 for XBox, Arctis (7 and Pro), Arctis 7+, Arctis Nova 7, Arctis 9, Arctis Pro wireless.
  • HyperX Cloud Flight Wireless
  • Corsair Void (Every void-version*, regardless whether Elite, Pro, HS70 Wireless)
  • Roccat Elo 7.1 Air

The application is a command line tool, though it has a graphical interface for GNOME 42+ (Ubuntu 22.04 / Fedora 35 and higher).

How to Install the HeadsetControl app

The app so far does not have binary package for Ubuntu Linux, though it’s not hard to build it from source. The following steps is tested and works in my case in Ubuntu 22.04 LTS.

1. First, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to install build dependencies:

sudo apt install build-essential git cmake libhidapi-dev

2. Then, clone the source by running the git command in terminal, and then navigate to the source folder:

git clone https://github.com/Sapd/HeadsetControl && cd HeadsetControl

3. Create ‘build’ sub-folder, navigate to that sub-folder and start building it:

mkdir build && cd build && cmake ../

4. Finally, run make and then make install to build and install the tool:

make -j4
sudo make install

Once successfully installed, it will output that ‘/usr/local/bin/headsetcontrol‘ and ‘/usr/local/lib/udev/rules.d/70-headsets.rules‘ installed.

How to Install the Extension for graphical UI

For Ubuntu 22.04 and higher, first search for and install “Extension Manager” from Ubuntu Software.

Install Extension Manager in Ubuntu 22.04+

Then, use “Extension Manager” to search and install the ‘HeadsetControl’ extension under ‘Browse’ tab.

Once installed, it should show the indicator applet in system tray area immediately with menu options to control your headset! Other Linux can go to this page to use ON/OFF switch to install the extension.

Uninstall:

To remove the extension, either go to the link page above and use ON/OFF switch, or use “Extension Manager” or Gnome Extensions tool.

To remove the command line application, open terminal and run command:

sudo rm /usr/local/bin/headsetcontrol /usr/local/lib/udev/rules.d/70-headsets.rules

Though, it’s universal Linux package format that runs in sandbox.

For users who prefer the classic .deb package format, The Debian/Ubuntu Games Team maintains an Ubuntu PPA with the latest stable/devel release (1.16.x stable at the moment) of the game packages. Which, so far supports Ubuntu 20.04, Ubuntu 22.04, Ubuntu 22.10, and their derivatives.

Type user password (no asterisk feedback) when it asks for sudo authentication, and hit Enter to continue.

3. If a previous 1.16.x version of the game package was installed on your system, launch “Software Updater” (or Update Manager) to upgrade the game:

Or, run command in terminal to install/upgrade the game package:

sudo apt instatll wesnoth-1.16

NOTE: Linux Mint user may first run sudo apt update to refresh package index.

Once installed, search for and launch the game either from start menu or ‘Activities’ overview depends on your DE and enjoy!

Uninstall:

To download the game to the stock version available in system repository, open terminal (Ctrl+Alt+T) and run command:

sudo apt install ppa-purge && sudo ppa-purge ppa:pkg-games/wesnoth-devel

This command will install ppa-purge tool and purge the PPA, which also downgrade installed packages.

To simply uninstall the game package, use command:

sudo apt remove --autoremove wesnoth-1.16

Also remove the PPA, either via “Software & Updates” under Other Software tab in Ubuntu, or use “Software Sources” tool in Linux Mint, or run command:

sudo add-apt-repository --remove ppa:pkg-games/wesnoth-devel

That’s all. Enjoy!
