Solaar is a Linux manager for many Logitech keyboards, mice, and other devices that connect wirelessly to a Unifying, Bolt, Lightspeed or Nano receiver as well as many Logitech devices that connect via a USB cable or Bluetooth. Solaar is not a device driver and responds only to special messages from devices that are otherwise ignored by the Linux input system.
