Automatic startup script/program Linux Mint 12/LXDE

Postby Krookroo on Sun Mar 18, 2012 11:44 am

Hello all.
I'm new to linux for one week now. For the moment, linux mint is quite a pleasant os to use, but as I'm still new it is still inferior to "windows ?" in my hands in terms of productivity (which doesn't mean that I consider LM12 inferior of course, this is just a statement).
In an attempt to "customize" my OS and getting it better suited to my needs, I wish to be able to add scripts or programs to be launched on startup. After a bit of searches over this forum and the web, here is where I am:

=> A tip I could read was to go through the startup application manager, however (unless I made an embarrassing mistake) in LM12 LXDE, in the menu/preference what I have is the "desktop session settings" which seems to manage the startup program, and I wasn't able to find how to add a line or script. However, even if it would have worked this way the solution would have been totally distro-dependant since I would'nt have been able to do the same on another distro without this feature, so quite happily I thought that I had to learn a few things to get it work!

=> Tried to play with the /etc/init.d directory. What I basically did was:

1/ creating a test script in /etc/init.d:

test:
#! /bin/sh

PATH=/usr/sbin:/usr/bin:/sbin:/bin
DESC="enables logitech g300 mouse to work properly"
NAME=test
SCRIPTNAME=/etc/init.d/$NAME


# Define LSB log_* functions.
# Depend on lsb-base (>= 3.0-6) to ensure that this file is present.
. /lib/lsb/init-functions

#
# launches lxterminal
#
do_start()
{
lxterminal
}

#
# does nothing
#
do_stop()
{

}

case "$1" in
start)
do_start
;;
stop)
;;
restart|force-reload)
;;
esac

:

What I did here was taking another script which seemed to work at startup, deleting the entries which I though had only something to do with the initial task and not with mine. As I didn't really had a clue about what the lsb stuff at the beginning was here for, I did let it stay.
I also made the file executable through:
Code: Select all
chmod 755 /etc/init.d/test


2/ Link it to the file that will be used at startup (don't really have a clue about how this works, neither about how the startup process is going on, but...)
I went
Code: Select all
sudo update-rc.d /etc/init.d/test defaults

It actually seemed to work and create the links even if the lsb wasn't very happy (I suppose I did delete too much things in when I wrote "test", however I kept going on since I read that lsb was some kind of a "model" which files in here should adopt for stability issues or something along the way and did not seem to prevent execs from working, but I may(must) have read too fast).
(maybe I had to deal with some permission issues along the way also, I don't really remember, sorry about not being able to be more precise)

3/ Reboot and no lxterminal got launched.

I also have a few questions:
-> which programming language is used in "test"? I searched a few minutes though google but wasn't able to find it out, probably a keyword issue, I ask this because it will be faster and possibly more precise that way. If you think it is only laziness then sorry and don't take the time to answer :)
-> does the problem come from the command line to call the program? I did this way because I sort of thought that I read this was the way the previous file went to call programs.
-> how (very basically of course, just to get the starting idea from which I will be able to document myself efficiently) does the system boots (loading of kernel then??? in fact the "mechanics" of booting)
-> In my opinion, loading a script or a program on startup would be exactly the same in terms of command lines and stuff, because to read a script and having it have an effect I need to call a program which runs through the script. Am I right?
(if not then it's stupid for me to "test" by launching lxterminal because the first idea was to launch a script (to fix some hardware issue)

Thank you in advance, and sorry for the huge post!

Edit: I forgot to mention that I'm not really advanced in the world of computer sciences. I have a few basics of how things work, and had basics courses in the university and a few hours using python as a programming language but please consider me as someone who doesn't know a programming language, just switched to linux and wasn't an advanced user under windows.

Looks like I'm starting quite well in the wrong section, sorry about that.
Might a moderator move my topic to the appropriate (LXDE/newbie questions) or should I copy it there myself and they will delete this one?

Not sure if this is what you want but for starting programs or scripts in LXDE you can do this: http://blip.tv/file/get/Llelectronics-L ... art754.m4v

If the script starts with "#! /bin/sh" then it's Bash but you can start others:
Some typical shebang lines:

#!/bin/sh — Execute the file using sh, the Bourne shell, or a compatible shell
#!/bin/csh — Execute the file using csh, the C shell, or a compatible shell
#!/usr/bin/perl -T — Execute using Perl with the option for taint checks
#!/usr/bin/ruby — Execute using Ruby
#!/usr/bin/python -O — Execute using Python with optimizations to code
#!/usr/bin/php — Execute the file using the PHP command line interpreter

Thank you for the information about the start of files that could be used, your links are bookmarked.
Thanks to also your first link, I managed to bring an application at startup. However the .sh script doesn't seem to load. Just in case, here's the line in the xxx.desktop file:
Code: Select all
Exec=~/.ipconfig/autostart/logitechg300.sh

I strictly followed the video. I have the exact same file working with
Code: Select all
Exec=lxterminal


I did not try with "Exec=sh file.sh" but I'm not really sure it's worth the 30 seconds.

Edit: yes, this tip would basically do the job, but I was looking for a more "dirty hands" way to do this, in order to learn some useful stuff. In fact, I'm new to linux, and decided to go with a "ready" distribution as a start and moving as fast as possible to a more tunable environment, hence my questions.

I'm not sure what you are trying to do, but if you just add lxterminal to autostart, it will launch at boot. Similar for exec of any application. Autostart is at /etc/xdg/lxsession/lubuntu/autostart. http://lxlinux.com

Okay, maybe I did not write things clear enough, english isn't my first language so apologizes about this :)
In fact, my mouse does not work well in linux mint. I have a bash script which fixes this, but I have to manually launch it each time I log in, and this is annoying, so I tried to look how to get it launched automatically on startup. For my tests on how to "manually automate the autostart", I used lxterminal, because it is faster for me to see if it worked, and I don't have my mouse allways plugged on my laptop.

I'll have a look at your links, thank you for taking the time :)

Edit: many thanks. If anyone else asks himself the question:
sudo leafpad /etc/xdg/lxsession/Mint-LXDE/autostart
add simply a line:
@yourcommandline
and it works.

Hop, in fact the problem is not fully solved:
this solution is ran twice at login! I would like to have it run only once!
I made a test by adding at the end of the file
Code: Select all
@lxterminal

and on startup I have two of them launching (and of course when I comment that line I don't have any popping up!)

Not that it is a problem in that case (since I have another location where I can put my link towards an application for startup), however if I want to custom things with a script that shouldn't be ran twice, then the solution isn't one.

Any idea?

Krookroo, have you tried to copy the .desktop file of the program you want to autostart into /home/[user]/.config/autostart? The .desktop files can be found in /usr/share/applications. Once the program's .desktop file is in /home/[user]/.config/autostart, you should be able to go to Menu > Preferences > Desktop Session Settings and enable/disable autostarting the program under Automatically Started Applications.

This method has worked well for me, but I found my way to this thread because I am currently having problems getting Thunderbird to autostart.
