Solaar, Logitech Unified Mouse/Keyboard Configuration App

 I bought a new Logitech M720 Mouse.  It can connect via Bluetooth or a Logitech Unified USB Dongle.  In addition, it can connect to three different device.  Since I already have a Logitech keyboard that is using a unified USB dongle I wanted to pair the new mouse with the old unified USB dongle.  There was no way to do this through hardware and the instructions said you had to use the Logitech software on either a MS Windows Machine or and Apple.  After a little research I found a nice little app called Solaar.  It gives you a way to communicate with your Logitech hardware (mouse/keyboard/unified USB receiver) and pair your peripherals with the unified USB receiver.  It also lets you change some of those peripherals settings, basically giving you a Linux version of the Logitech software.

To install it on Ubuntu 22.04 simply open a Terminal Window and type:

sudo apt install solaar

When it's done simply run the solaar app by typing solaar into your terminal window or finding the app in your start menu.  You should see your Logitech Unified USB Dongle listed.  If not just unplug and plug the dongle back in.  Once you see the dongle simply highlight it and click on the "Pair New Device" button in the lower left corner and follow the onscreen instruction.



Clicking on the different devices you will get their configuration setting and see their battery levels.  Click on the Lock Icons to change the setting.  Lock them back when finished.  Notice in my screen shots my old mouse is grayed out because it is turned off.  My unified USB dongle said it can have 6 devices connected to it.  I currently have 3.
