I have a script running thru crontab that calls a QT popup (named shutdown_warning). The popup does not display on the screen and the error received is:

shutdown_warning: cannot connect to X server

The script calls "shutdown_warning" from roots home directory. The crontab is being executed from root.

It displays fine on the user console if, as root, I execute the script and export $DISPLAY:1.0

I need this popup to display on the user console and all remote console connections.

Any help would be appreciated.

Is it enough to just put DISPLAY=1:0 at the beginning of the crontab file that describes the job? If that environment variable is all that's missing, that's all you have to do. --Danny
