# 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][K750] 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][K750] and
  [K800][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][P_MX].

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


# Supported features

These tables list all known Logitech [Unifying][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).
