How can I execute my gtk-based program after system boot?

See more:

I have Ubuntu-server 16.04. Installed gtk3 and can execute my program manually by this command: ./img when I go to it's directory /home/m:
[^]
But when I try to execute my program from outside the /home/m folder by this command:

/home/m/img &

It only shows an icon inside a little window in bottom right of the screen.
Why it happens and how can I fix it?
[^]
And my second question is here: I did add this line:

/home/m/img &

to my

/etc/xdg/openbox/autostart

file, and it works after login but doesn't show my image, it shows only a file icon at center of the screen. I think it's same as previous problem!
[^]
How should I fix it?

What I have tried:

My goal is building a gadget, when user turns it on, it shows a welcome image, then waits for user's voice command, then shows another image respect to command and backs to welcome page again. there is no other menu or option for user. This is the whole system I like to build by Linux and for this reason I chose Ubuntu-server (because I don't need to desktop environment and menu and other regular apps). then I installed openbox on it. And now I am trying to find a way that my program starts at boot(like a Kiosk) and the only thing user can do is phyisically turning on/off the system by power button! Or telling some voice command when the system is on

Without more information it is impossible to guess. Why are you running this in the background? And if you want a program to start after boot, you need to put it in a fixed location, not your home directory.

We still do not know anything about your program or what it is supposed to do.

Hello Richard, sorry if I am too late, I was challenging with other problem. What kind of information should I put? where should I put my program as a fixed location?

Put it in a fixed directory that is available to the operating system. You should study the architecture of whichever version of Linux/UNIX you are working with.

I use: Linux nanopim1 3.4.113-sun8i #16 SMP PREEMPT Tue Jun 13 14:15:57 CEST 2017 armv7l armv7l armv7l GNU/Linux

Not every answer is in Google. Sometimes you actually have to sit down and study the documentation.

Member 13376650 22-Nov-17 4:51am

But I don't really know which topic I must study for

Richard MacCutchan 22-Nov-17 5:01am

Get hold of a good book on Linux and study it all.

Dear Ricahrd! This is a little part of my robot project! I had many things in Voice and image recognition before and must do many things later! How can I read a full book about Linux too?

I did edit my post in `what I have tried` section.
