I have following python script, and want to run it with cron so that every minute cron will popup a message.

#!/usr/bin/python
# -*- coding: utf-8 -*-

import gtk.gdk
import pynotify
import random

m=[]
m.append("test1")
m.append("test2")
m.append("test3")

n = pynotify.Notification(random.choice(m))
n.set_hint('x', gtk.gdk.screen_width()/2.)
n.set_hint('y', gtk.gdk.screen_height()/2.)
n.show()

This is my cron script:

* * * * * export DISPLAY=:0.0 && /home/user/scripts/notifications.py >/dev/null 2>&1

Unfortunately nothing happens. Can you help please?

From this thread at Ubuntuforums, you're possibly running into xauth problems. X tends to be paranoid about giving display/input access to outside processes, even from the same user.

In an X terminal window, type: xhost local:$USER and see if your cron job works. If so, add that command to your ~/.bashrc file and the fix should persist.

In case anyone else is wondering. I had to export DISPLAY and XAUTHORITY

I'm running this script in cron:

export XAUTHORITY=/home/user/.Xauthority
export DISPLAY=:0
python ~/notifications.py

I had similar problems with a script that just need info from GNOME via the X session vars. Truly truly annoying stuff. –  ajstein Jun 15 '11 at 15:00
