CONFIGURATION

Anonymous (anonymous@undisclosed.example.com) — 2022-02-15T20:09:05+00:00

CONFIGURATION The config file (default: /etc/lcd4linux.conf) contains the configuration and layout of LCD4Linux. Starting with 0.10, the format changed a lot, and is now much more flexible. Any text on a line after a hash character ('#') (and empty lines) will be ignored (If you want to use '#' in a value (think of X11-colors), you have to quote it with a backslash). Empty lines and lines containing only whitespace characters will be ignored, too.
