The Logitech G13 is a 25-key "advanced gameboard" from Logitech's Gaming series, with the intention of replacing the left half of your keyboard whilst gaming. It uses rubber dome key switches for the main 22-keys, mouse-like buttons for the two buttons around the joystick, a joystick (which can be pressed in), four Mode buttons, four option buttons, a menu button, and a backlight toggle.

## Installation

There are a couple options for drivers, but only one that appears to work well today:

- Running the official Logitech Gaming Software under Wine. Despite working fine, the software has a garbage rating on WineHQ, as it cannot actually communicate with USB devices (however, the reports available are quite old, and you may have better luck).
- linux-g13-driver-gitAUR is a maintained driver and configuration tool with modern C++ & Java Codebase for the G13, forked from the older linux-g13-driver (see README for more information).
- g13-gitAUR is an unmaintained user-space driver.

Both packages will install a g13d daemon and a systemd service that runs g13d as user/group `g13`. They will also set up rules for udev to identify your G13 device and automatic starting and stopping of the service by connecting or unplugging by default.

## Usage

Note The binary is named g13d, since there is already a binary named g13 within gnupg.

After following the steps above, when you reboot and launch g13d (either manually or automatically through systemd), you should receive an image with a "linux inside" logo, "G13", and the GNU logo.

## Configuration

Note When g13d is run as a systemd service it uses a fifo at `/run/g13d/g13-0` instead of the default `/tmp/g13-0`.

g13d is configured in one of two ways, either by writing commands to `/run/g13d/g13-0`, or preferably by specifying keybindings and commands in a configuration file which is read at launch.

When running g13d manually you can specify a configuration file using the `--config` parameter, and when running as a service the file `/etc/g13/default.bind` will be used.

Note In most cases, specifying your default keybindings in `/etc/g13/default.bind` is the easiest option. You may need to create the `/etc/g13 directory` if it was not created during initial install.
Tip You can take inspiration from an example default.bind file.

Manual commands can also be evoked one at a time by manually writing to `/run/g13d/g13-0`:

For example, to set the display a purple colour:

    $ echo "rgb 177 13 201" > /run/g13d/g13-0

g13 can also handle multiple commands at once:

    $ echo -e "rgb 177 13 201\nbind G4 KEY_W" > /run/g13d/g13-0

Tip g13 can handle multiple commands at once, and will ignore lines starting with `#`. You can use this to make files full of commands and run `cat file > /run/g13d/g13-0` when you are ready to play.

## Commands

### rgb

Set the backlight to an rgb colour, values are expressed in decimal from 0 to 255.

    rgb rrr ggg bbb

For example, to set the display green:

    rgb 0 255 0

### bind

Binds a G13 key. All keys are bound to `a` by default.

    bind g13key actual_key

For example, to setup WASD movement:

    bind G4 KEY_W
    bind G10 KEY_A
    bind G11 KEY_S
    bind G12 KEY_D

See below for how to configure this.

### mod

Sets the backlight status of M1, M2, M3, and MR.

    mod n

Where `n` is a bitmask. To find the desired state compute the sum of 1 (M1), 2 (M2), 4 (M3) and 8 (MR).

For example, to set M1, M3, and MR on, and turn M2 off (1+4+8=13):

    mod 13

Since that can be less than explanatory, here is a diagram showing where the keys physically are on the device:

    Keypad:

       G15  G16 G17 G18  G19
           G10  G21  G22

    Joystick:
     L            STICK_UP
     E  STICK_LEFT  TOP   STICK_RIGHT
     F           STICK_DOWN
     T
                   DOWN

Tip As a jumping off point, you can use default.bind, which has the same bindings as the default profile when using the official software, along with a purple backlight.
