G15Daemon(1) 1 G15Daemon(1)

g15daemon - provides access to extra keys and the LCD available on the logitech G15 keyboard.

G15Daemon allows users access to all extra keys by decoding them and pushing them back into the kernel via the linux UINPUT driver. This driver must be loaded before g15daemon can be used for keyboard access.

The G15 LCD is also supported. By default, with no other clients active, g15daemon will display a clock. Client applications and scripts can access the LCD via a simple API.

The current version of G15Daemon understands the following options:

-v Show version info.

-s By default, g15daemon uses the L1 key to switch between client screens. Using this switch on the cmdline alters this, making MR (Macro Record) the button to achieve this function.

-k Stop a previously running copy of G15Daemon. For the keys and LCD to work, you'll have to restart the daemon manually.

-h Show a brief summary of commandline options available.

G15Daemon must be run as the root user, either from a startup script (sample scripts are available in the contrib folder) or manually, via the su command.

To run the daemon with default options, run:



g15daemon -s to have the MR key as the client screen switch.

If all required libraries are installed and in locations known to your operating system, the daemon will slip quietly into the background and a clock will appear on the LCD. Congratulations! The linux kernel will now output keycodes for all your extra keys.

Current versions of the Xorg Xserver dont have support for the extra keys that g15daemon provides. This support will be available in the next release of Xorg (7.2).

For now, if you want access to the extra keys for hotkey support in X11, you need to run the xmodmaprc script on each start of X. This script is available in the contrib folder (if g15daemon is installed in the default location, the contrib folder is in /usr/share/doc/g15daemon-${VERSION}/contrib

Depending on your linux distribution, copying the xmodmaprc file (or pasting the text below) into ~/.Xmodmap may be all that's required.

Copy the following into ~/.Xmodmap (depending on your distribution) for X11 to recognise all extra G15 keys:
