Allow root to create a popup on screen

Asked by Adam314 in Linux, Linux Programming, Linux Network Security

Tags: , , ,

I have a script that is run by root from cron.  If there is a failure, it creates a log.  I want this to also create a popup.  I am using zenity to create the popup.  I am running Ubuntu 7.04 distro.

The script sets the DISPLAY:
export DISPLAY=:0.0

When the zenity command runs, it gives these errors:
Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified

If I run xhost for a particular user, and set XAUTHORITY to that users ${HOME}/.Xauthority file, then I can get the popup.  But I want the popup to be able to show up no matter what user is logged in.  And if I create a new user, I don't want to have to run xhost for that user...

I want the zenity to work no matter what user is logged in.  Is there a way to say root always has permission to connect to the display?
