The Solaar program manages connections with Logitech Unifying receiver on Linux, including pairing/unpairing. This means wireless keyboards and mice, including wireless trackballs work well on Linux. Logitech wireless firmware updates are provided seamlessly in Linux. The Unifying receiver “just works” on Linux upon plugging in, with trackballs being recognized as an HID device.
Solaar is strictly a GUI program, so you will need a display or VNC graphical desktop to perform operations like
- configuring buttons
- monitoring battery level
- checking firmware version of Unifying receiver and connected devices
Logitech Unifying receivers can be paired with multiple devices. This allows one to carry a laptop from home to office without dragging the wireless keyboard or mouse along.
