Supported devices

Solaar will detect all devices paired with your Unifying Receiver, and at the very least display some basic information about them.

For some devices, extra settings (usually not available through the standard Linux system configuration) are supported:

• The K750 Solar Keyboard is also queried for its solar charge status. Pressing the Light-Check button on the keyboard will pop-up the application window and display the current lighting value (Lux) as reported by the keyboard, similar to Logitech's Solar.app for Windows.

• The state of the FN key can be toggled on some keyboards (K750 and K800). It changes the way the function keys (F1..F12) work, i.e. whether holding FN while pressing the function keys will generate the standard Fx keycodes or the special function (yellow icons) keycodes.

• The DPI can be changed on the Performance MX Mouse.

• Smooth scrolling (higher sensitivity on vertical scrolling with the wheel) can be toggled on the M705 Marathon Mouse and M510 Wireless Mouse.

Supported features

These tables list all known Logitech Unifying devices, and to what degree their features are supported by Solaar. If your device is not listed here at all, it is very unlikely Solaar would be able to support it.

The information in these tables is incomplete, based on what devices myself and other users have been able to test Solaar with. If your device works with Solaar, but its supported features are not specified here, I would love to hear about it.

The HID++ column specifies the device's HID++ version.

The Battery column specifies if Solaar is able to read the device's battery level.

For mice, the DPI column specifies if the mouse's sensitivity is fixed (-), can only be read (R), or can be read and changed by Solaar (R/W).
