Solaar

Solaar usage

Under normal usage Solaar creates an icon in your system tray. This icon is usually a battery icon showing the approximate battery level for your device with the lowest known battery level. If there are no battery information, then the icon is one of the Solaar icons.

Solaar also has a main window. When it is invisible, click on the icon in the system tray to bring up the menu, and then click on a receiver or device in the menu.

The following is an image of the Solaar menu and the icon (the battery symbol is in the system tray at the left of the image). The icon can also be other battery icons or versions of the Logitech Unifying icon.

Clicking on “Quit” in the Solaar menu terminates the program, and “About Solaar” pops up a window with further information.

Solaar options

There are several options that affect how Solaar behaves:

Solaar main window

The Solaar main window shows your Logitech receivers and devices that Solaar knows about and can be used to pair new devices, unpair paired devices, and view and change some settings of the selected receiver or device. To select a receiver or device click on it in the left side of the window.

Closing the main window does not terminate Solaar (unless Solaar is not using the system tray). Clicking on “Quit Solaar” terminates the program, and “About Solaar” pops up a window with further information. The light bulb (or a similar icon) displays detailed information about the selected receiver or device (useful for debugging).

Pairing and unpairing devices

When a receiver is selected in the main window, you can pair a new device by clicking on the “Pair new device” button. Then turn on the device and it should pair with the receiver if that is possible.

Some receivers can only pair with certain kinds of devices, other receivers pair a new device by replacing an existing paired device of the same kind, and even other receivers can only pair a limited number of times. A receiver with the Unifying logo should be able to pair with any device with the Unifying logo. If there are no open pairing slots, however, you may not be able to pair a new device. In this case to pair a new device you first need to unpair a device.

When a device is selected you can unpair the device if your receiver supports unpairing. To unpair the device, just click on the “Unpair” button and confirm in the window that pops up.

Viewing and changing device settings

When a device is selected you can see the approximate battery level of the device, if that is reported by the device, and the status of the link between the device and its receiver. You can also see some settings of the device and change some of these. Changing settings is performed by clicking on buttons or moving sliders.

If the selected device is powered down or otherwise disconnected its settings cannot be changed but it still can be unpaired if its receiver allows unpairing.

Remapping key and button actions

For many devices Solaar can remap some of their keys or buttons to perform a different action. (This changes the information that the device sends when the key or button is activated.) Only some keys on some devices can be remapped and they can only be remapped to a limited number of actions. The remapping is done by selecting a key or button in the left-hand box on the “Action” setting line and then selecting the action to be performed in the right-hand box. The default action is always the shown first in the list. As with all settings, Solaar will remember past action settings and restore them on the device from then on.

Solaar-main-window-actions

The names of the keys, buttons, and actions are mostly taken from Logitech documentation and may not be completely obvious.

It is possible to end up with an unusable system, for example by having no way to do a mouse left click, so exercise caution when remapping keys or buttons that are needed to operate your system.

Solaar command line interface

Solaar also has a command line interface that can do most of what can be done using the main window. For more information on the command line interface, run solaar --help to see the commands and then solaar <command> --help to see the arguments to any of the commands.
