According to the example from:

How can I start X11 only for a single application?

I'm running python script that shows Tkinter frame by invoking:

startx ./script.py

... when the script is done, it exits with:

root.destroy() # Tk() from Tkinter

... however X server seems still to be running (blank screen is displayed and I have to use Ctrl+C to get access to the console back).

How can i make xserver stopped immediatelly when following application exits?

EDIT: I've noticed that if i didn't use MyThread (but e.g. timer handler method), closing X windows session works fine. Also this script finishes properly when run (tested) on Windows.

Code with issue:

#!/usr/bin/env python

import sys
import threading
import time
from Tkinter import Tk, Frame, BOTH

SCREEN_RES = "1024x600"
DELAY = 1000
TK_ROOT = Tk()

class MyThread(threading.Thread):

    def run(self):
            print "Entering MyThread..."

            print "Exiting MyThread..."    

        except KeyboardInterrupt:

# noinspection PyAttributeOutsideInit
class SysInfo(Frame):
    mt = MyThread()

    def __init__(self, parent):
        Frame.__init__(self, parent, background="gray")

        self.parent = parent

        self.after(DELAY, self.on_timer)

    def init_ui(self):
        self.pack(fill=BOTH, expand=True)

    def on_timer(self):
        print("Timer fired.")
        self.after(DELAY, self.on_timer)

def main():
    TK_ROOT.geometry("%s+0+0" % SCREEN_RES)

According to the flipping manual, which I hope you have found the chance to read, normally startx(1) will look in order for ~/.xinitrc then in the xinit library directory for a system default xinitrc script to run - but as you have provided command line client arguments instead (./script.py) that is used instead. You might find it instructive to look for the system wide script for clues as to how things are normally done.

I think you may get somewhere with further arguments after a -- on the line that you use, arguments after that symbol are server arguments, one of which may be relevant is -terminate which according to the X server command line help:

causes the server to terminate at server reset, instead of continuing to run. This overrides a previous -noreset command line option.

Perhaps this can give some possible pointers...
