Solaar
Manager for Logitech keyboards and mice. Shows battery level, pairs devices to a receiver and changes button behaviour.
Our verdict
Solaar is what Logitech owners install on Linux instead of Options or G HUB. Its most-used job is the simplest one: it tells you how much battery is left in the mouse and keyboard, which nothing else on the desktop does.
Beyond that it pairs devices to a Unifying, Bolt, Lightspeed or Nano receiver, so a mouse that came unpaired can be put back without hunting for a Windows machine. It also exposes the settings the device itself offers, which usually covers scroll wheel behaviour, pointer speed and reassigning a few buttons.
It is not a full replacement for G HUB. Per-game profiles and the more elaborate macro work are not here, and what you can change depends on the model in your hand. For a work mouse and keyboard it covers everything most people ever touched.
What's good
- Shows the battery level of each Logitech device, which Linux otherwise hides from you
- Pairs and unpairs devices with a Unifying, Bolt, Lightspeed or Nano receiver
- Changes scroll behaviour and reassigns some buttons
- Free, and sits quietly in the system tray
What to know first
- Logitech only. It will not touch a keyboard or mouse from any other maker
- Not everything G HUB does is here, and the deeper gaming settings are missing
- Which settings you get varies by model, because each device exposes a different set
- The window is a plain list of options rather than the visual layout Logitech gives you
