    I have been trying to setup lcdproc on my pi for a few days now and i am not having much luck i am using a 20x4 lcd with a i2c adapter i have changed the conf file to the hd44780 driver and all i get is two lines of blocks and a flashing back light if i change the driver to curses and run it i get the lcdproc server in my terminal window ??

    here is a copy of my conf file

    # LCDd.conf -- configuration file for the LCDproc server daemon LCDd
    #
    # This file contains the configuration for the LCDd server.
    #
    # The format is ini-file-like. It is divided into sections that start at
    # markers that look like [section]. Comments are all line-based comments,
    # and are lines that start with '#' or ';'.
    #
    # The server has a 'central' section named [server]. For the menu there is
    # a section called [menu]. Further each driver has a section which
    # defines how the driver acts.
    #
    # The drivers are activated by specifying them in a driver= line in the
    # server section, like:
    #
    #   Driver=curses
    #
    # This tells LCDd to use the curses driver.
    # The first driver that is loaded and is capable of output defines the
    # size of the display. The default driver to use is curses.
    # If the driver is specified using the -d <driver> command line option,
    # the Driver= options in the config file are ignored.
    #
    # The drivers read their own options from the respective sections.
    
    ## Server section with all kinds of settings for the LCDd server ##
    [server]
    
    # Where can we find the driver modules ?
    # IMPORTANT: Make sure to change this setting to reflect your
    #            specific setup! Otherwise LCDd won't be able to find
    #            the driver modules and will thus not be able to
    #            function properly.
    # NOTE: Always place a slash as last character !
    DriverPath=/usr/lib/lcdproc/
    
    # Tells the server to load the given drivers. Multiple lines can be given.
    # The name of the driver is case sensitive and determines the section
    # where to look for further configuration options of the specific driver
    # as well as the name of the dynamic driver module to load at runtime.
    # The latter one can be changed by giving a File= directive in the
    # driver specific section.
    #
    # The following drivers are supported:
    #   bayrad, CFontz, CFontz633, CFontzPacket, curses, CwLnx, ea65,
