The G15daemon is a userspace driver/multiplexer for the keyboard and its LCD, using libg15 for low-level keyboard control. Some of the features of g15daemon are:
•Allows all extra G15 keys to be used in applications.
•It allows for multiple simultaneous LCD clients.
•Virtualises the LCD, the user can select which application is displayed with a simple keypress.
•Clients talk to the daemon via a simple protocol.
•Client applications have full control over LCD backlight and contrast.
•Perl and Python bindings are available in the archive.
•Lcdproc 5.1 contains a driver to talk to the daemon.
•A patch is available in the archive for version 1.3 of libgraphlcd, which allows any application using graphlcd to now use the keyboard's LCD via the daemon. [The SVN version of graphlcd now includes the driver this patch provided].
•Shell scripts can talk to the daemon via g15composer.
•G15daemon now has Mac OS X support. Check out the download section for some binary files. A Mac OS X howto is also available (Thanks to Fabrizio Sestito).
