Thanks, that was a very good advice. Indeed maemo uses upstart.

I have checked the post about batlevel and it helped a lot, finally my script starts at the startup time.

Now, I see I have some other problems also.

I want to start a Qt application and show the window to the user, the problem is, that the application does not want to start(is terminated?), though I have no problems to run it from applications menu or the command line.

I have heard, that I should split my code to 2 applications ( non graphical daemon, and the window app), but I would prefer having only one.

Any ideas?
