What Solaar is
Solaar is free software for managing Logitech keyboards, mice, trackpads, and other supported devices on Linux. Devices can connect through Unifying, Bolt, Lightspeed, or Nano receivers, USB, or Bluetooth. Solaar can pair and unpair supported hardware, show information such as battery status, and change available settings. Depending on the device and receiver, settings may include scroll behavior, sensitivity, backlighting, function keys, polling rate, and onboard memory; some devices also support key or button remapping. User-editable rules can react to device notifications, such as changing the speed of certain thumb wheels. Solaar runs as a graphical application or command-line interface and stores device settings in ~/.config/solaar/config.yaml. The project is distributed under GNU GPL version 2 or later. Bluetooth connections themselves still use normal Bluetooth mechanisms.
