[lcd4linux] Automatically start lcd4linux and Ubuntu

[Jan P. <jp...@mg...>]

Hi All,

Since a day or two, I'm now using lcd4linux to show some messages on a 
MatrixOrbital LK202-25 LCD Display. Everything is working fine, I also 
managed to get my own personal message on the display when it is turned on.

But now I would like to automatically start lcd4linux when my ubuntu 
boots. So I followed the guide on the website and created the lcd4linux 
file under /etc/init.d/ with the code found here 
(http://ssl.bulix.org/projects/lcd4linux/wiki/Howto) and I also created 
the softlink /etc/rc5.d/S99lcd4linux

But when I boot my Ubuntu, the lcd4linux isn't starting at all. Should I 
do something more to launch the lcd4linux when booting Ubuntu???

An other issue that I would like to solve is that when I manually boot 
lcd4linux (sudo /etc/init.d/lcd4linux start) I first get a message:

LCD4Linux 0.11.0-SVN
lcd4linux.bulix.org

I would like to remove this message and replace it with my own. Where 
should I change this message? I figured out that the message is in the 
file drv_generic_text.c, but I think that that's not the place to change 
the message since at that point, I'm messing with the main code...

All help would be great!!

Thanks in advance!

Hi,

Ok the first part of my question is already solved... Using the method:
update-rc.d lcd4linux defaults

solved my problem and lcd4linux is now running when booting the system...

As far as I know, that's the only option, to get a custom message. 
Running lcd4linux with the "-q" switch supresses the message altogether 
(if I recall correctly), but I'm not aware of setting a custom message 
without hacking the source code.

I hope that helps

Martin

Martin is right: there is no way to customize the startup message, you can only suppress it using the -q flag.

Hi all,

Thanks for the information, I used the -q option and everything is fine. 
My welcome message is shown until the lcd4linux is booted on the Ubuntu 
platform. At that point, my data is shown as it should, without the 
startup message!!

Thanks
