daemon for ''lcd'' display devices


lcd4linux [OPTIONS...]


LCD4Linux is a small program that grabs information from the kernel and some subsystems and displays it on an external liquid crystal display.

If started without any options, it will try to read its configuration from  /etc/lcd4linux.conf and daemonize. Please make sure your configuration file is owned by the user you run lcd4linux (typically root) and has permissions 600.


Alternate configuration file to read. Use this switch to make lcd4linux read another file than /etc/lcd4linux.conf.


Run in forground and don't daemonize. Useful for debugging.
