Zenity Popup on logout

[drzoo2]

I am trying to create a Zenity dialog pop-up when a user logs out. I had this working on Ubuntu Jaunty but after switching to LMDE I can't seem to get it to work.

I'm using /etc/gdm3/PostSessions/Default and adding a line to run a script.
This works fine and when logging out the script is called but I'm not seeing the pop-up.

Here is my test case for the popup and a dummy action.

Code: Select all

DISPLAY=:0 XAUTHORITY=/home/scott/.Xauthority sudo -u scott zenity --info --text="Please Wait. Backup in Progress." &
touch /home/scott/Desktop/test

When ran from terminal I get the following.

Code: Select all

scott@linux-main:~$ ./.rsync_home
No protocol specified

(zenity:14023): Gtk-WARNING **: cannot open display: :0


Something change in the x-server that is causing this or is it my Authority file in my home directory?

Now honestly I wrote this a few years ago so I don't recall how I came to the parameters I did. Lots of research.
