It is available though the ppa:daniel.pavel/solaar PPA (if you do not know how to install such a "PPA", see What are PPAs and how do I use them?).

After doing so, you can pair a new device with the sudo ltunify pair command and unpair devices with a command like sudo ltunify unpair mouse (be sure to have a second device that you can use after detaching your Unifying device!).Ī graphical tool is also available, Solaar. This will fetch the sources and install the program to $HOME/bin/ltunify, if $HOME/bin did not exist before, then you may have to re-login or reopen your terminal. Quick installation instructions if you are in a hurry: sudo apt-get install git gcc For Linux, I have created the ltunify tool which is described in detail on my article Logitech Unifying for Linux: Reverse Engineering and unpairing tool.

Meanwhile, USB Bluetooth dongle designed to immediately connect with the mouse seamlessly.
Please refer to the manual book to follow the step-by-step of the pairing process. If you consider using an onboard Bluetooth, it may require manual installation by adding a new device.
On the other hand, if the mouse did not include a dongle in the product packaging, it means the device can work with a built-in Bluetooth - no extra dongle needed. Manufacturers usually provide extra dongle just in case their customers didn’t have a Bluetooth connection on their devices. Only plug-in dongle if your device doesn’t have Bluetooth.
If your notebook, laptop, or desktop PC already has a Bluetooth connection, then USB dongle may not be necessary to be plugged in. Some Bluetooth mouse bundled with USB dongle but it still works fine without it. Yes, you can use a Bluetooth mouse without its USB dongle
