I have made executable file of python tkinter application. It runs well when clicked. But I want to run it at Boot time (AutoStart) in Raspberry Pi Os.

I have tried many methods but they didn't work.

One method which I tried will other applications:

>sudo nano /etc/xdg/lxsession/LXDE-pi/autostart

@/home/pi/Downloads/exes/project2/work/dist/homeP (@path_of_file/applicatin_name)
This didn't work with my Current application, Even no error is observed. Please help me ??

Welcome to LQ, sukritmt786.

I'm no programmer but I can tell you you're probably missing stuff if you're programming on that. It only weighs in about 6G. It's very small with includes, docs, libs, & shares all cut down. I'm trying to slim slarm64 at the moment because I'm low on space on my 20G / partition.

Does this file properly execute when the command is entered exactly as you have written it?
If so then may be a matter of entering a proper line for autostart.
If not then there is something wrong with the file itself. Maybe permissions, maybe file structure, ?

You did not state if this is a binary executable or script.
If script then the autostart would try to run it as an 'sh' script while your user likely uses 'bash'. This could present a problem since the shells are different and the script would need to have the shebang line to ensure it is properly executed for whatever shell language is used. The way you phrased this seems it may be a python script/app so it must be executed appropriately.

Note that clicking on a file is not the same as using a command line, and the first step to getting it to run with autostart is ensuring that it properly executes at the command line. If it requires the gui to start then it may not run with autostart.

Create a first file
create a second file

go out (store it) and make it executable (in a file manager)
thats it
