how to make linux mint run only one gui program as startup

[behruzMo]

Hi.
I wrote a program with pyqt i want my os to be turn key.When the system runs only shows my logo and doesn't go to common desktop and just run my QApplication as only program in start up.I've tried

Code: Select all

startx mypro

but it's not full screen.

It's your program, your code controls the window state, there is no window manager to do it for you.

I don't want the user see os aspect and desktop

I understood that part, and that's fine, there's no need to run a desktop, I'm just telling you that the window controls require a window manager, and since you are not starting one your code needs to handle the startup window size/state on its own, see the Qt documentation.

Actually when i run my program in tty0 it works but user interface doesn't show.

Might is be something simple like Linux remembering the last state the program was in. I have an app in Base that is configured to open in a window in a particular location on the screen. If I edit it or do something to show full screen and forget to restore the window it does all sorts of strange things, (i.e. tries to show the window of the right size but in full screen - IOW it does not work!!!). Try exiting the program whilst in Full screen and starting form scratch again.
