This section talks about using LCDproc with LCD displays on Logitech G15 gaming keyboards.
If libg15daemon_client is present during build time, the g15 driver will include g15daemon support. If build with g15daemon support, the driver first tries to connect to the g15daemon. If the g15 is build without g15daemon support, or cannot connect to the g15daemon, it will use direct /dev/hidraw? device access. The g15 driver uses text and other rendering functions from libg15render. The g15daemon client-lib and libg15render are available from the g15daemon and g15tools projects at sourceforge.net.
If g15daemon is used, then input is provided by g15daemon, enabling use of the L1-L5 and G1 keys. When hidraw access is used the linux_input driver can be used for input.
