Beginners • Auto Run Python script error xdg_runtime_dir not set in the environment

I am trying to set up a Raspberry PI 3b to run a simple Python script to watch for a motion sensor then turn on a power supply ("led") and then play a wav file (see script below)

I have the PI set to boot to CLI. I can execute the script on the CLI: python \home\micgin<me instead of pi>\photosensor_rev1.py and the power supply turns on and the .wav file plays.

Now I want to python script to auto run after power on/boot. I have tried rclocal, bashrc and crontab as described in https://www.dexterindustries.com/howto/ ... t-startup/.

Using rclocal or bashrc or crontab per the website, The photosensor is working and the power supply turns on and off, but no wav file.

From looking at logs I think the error: xdg_runtime_dir not set in the environment

Any ideas what I am doing wrong.

Python script: photosensor_rev1.py

from gpiozero import MotionSensor
from gpiozero import LED
from time import sleep
import glob
import random
import pygame
pygame.init()

howdyfiles = glob.glob("/home/micgin81/Music/*.wav")

led = LED(17)
pir = MotionSensor(4)


while True:
pir.wait_for_motion()
print("You moved")
led.on()
pygame.mixer.Sound(random.choice(howdyfiles)).play()
pir.wait_for_no_motion()
led.off()
print("time out over")
