Requirements for Solaar
Installing Solaar from a repository should have set up all these requirements so in this situation you should be able to skip this section.
Solaar needs a reasonably new kernel (5.2+ should work fine),
with kernel modules
hid-logitech-hidpp loaded. Also, the
udev package must be installed
and its daemon running. If you have a recent Linux distribution, you are
most likely good to go.
Solaar requires Python 3.6+ and the
To run the GUI Solaar also requires Gtk3 and its GObject introspection bindings.
The Debian/Ubuntu packages that need to be installed are
in Fedora you need
if you’re using another
distribution the required packages are most likely named something similar.
You may have to install
gcc and the Python development package (
depending on your distribution).
If desktop notifications bindings are also installed
gir1.2-notify-0.7 for Debian/Ubuntu),
you will also see desktop notifications when devices come online/go offline.
For GNOME Shell/Budgie Desktop/KDE/XFCE support, you also need to have
gir1.2-ayatanaappindicator3-0.1 installed in Debian/Ubuntu. Although it is
recommended to install and use
gir1.2-ayatanaappindicator3-0.1 if it is
available, you can also use
gir1.2-appindicator3-0.1 if necessary (e.g.,
for Unity in Ubuntu).
Installing Solaar’s udev rule
Solaar needs to write to HID devices for receivers and devices. To be able to do this without running as root requires a udev rule that gives seated users write access to the HID devices for Logitech receiver and devices.
You can install this rule by copying, as root,
rules.d/42-logitech-unify-permissions.rules from Solaar to
You will probably also have to tell udev to reload its rule via
sudo udevadm control --reload-rules.
For this rule to set up the correct permissions for your receivers and devices you will then need to either disconnect your receivers and any USB-connected or Bluetooth-connected devices and re-connect them or reboot your computer.
Running from the Download Directories
To run Solaar from the download directories, first install the Solaar udev rule if necessary.
Then cd to the solaar directory and run
bin/solaar for the GUI
bin/solaar <command> <arguments> for the CLI.
Do not run Solaar as root, you may encounter problems with X11 integration and with the system tray.
Installing Solaar Using Pip
Python programs are usually installed using pip.
The pip instructions for Solaar are in
setup.py, the standard place to put such instructions.
To install Solaar for yourself only run
pip install --user . from the solaar directory.
This tells pip to install into your
.local directory, but does not install Solaar’s udev rule.
(See above for installing the udev rule.)
Once the udev rule has been installed you can then run Solaar as
Installing python programs to system directories using pip is generally frowned on both
because this runs arbitrary code as root and because this can override existing python libraries
that other users or even the system depend on. If you want to install solaar to /usr/local run
sudo bash -c 'umask 022 ; pip install .' in the solaar directory.
(The umask is needed so that the created files and directories can be read and executed by everyone.)
Then solaar can be run as /usr/local/bin/solaar.
You will also have to install the udev rule.
Solaar in other languages
If you want to have Solaar’s user messages in some other language you need to run
tools/po-compile.sh to create the translation files before running or installing Solaar
and set the LANGUAGE environment variable appropriately when running Solaar.
Running Solaar at Startup
Distributions can cause Solaar can be run automatically at user login by installing a desktop file at
If you install Solaar yourself you may need to create or modify this file or install a startup file under your home directory.
Installing from PyPI
As an alternative to downloading and installing you can install the most recent release
(but not the current github version) of Solaar from PyPI.
pip install --user solaar.
This will not install the Solaar udev rule, which you will need to copy from
/etc/udev/rules.d as root.
