Hi,
Am I having issues with getting this (http://learn.adafruit.com/drive-a-16x2-lcd-directly-with-a-raspberry-pi/init-script) to display at start up.
It runs fine if I run it manually and I have followed the guide but it stays blank on startup.
I am thinking the error must be related to when I run the following command.
$ sudo update-rc.d lcd defaults
as I get this message.
pi@raspberrypi ~ $ sudo update-rc.d lcd defaults
update-rc.d: using dependency based boot sequencing
insserv: warning: current start runlevel(s) (empty) of script `lcd' overrides LSB defaults (2 3 4 5).
pi@raspberrypi ~ $
Could someone please help me resolve this?
This is the contents of my /etc/init.d/lcd file
### BEGIN INIT INFO
# Provides: LCD

Thanks in advance.
