Cron with notify-send

Issue

I need to show a notification from a cron job. My crontab is something like:

$ crontab -l
# m h  dom mon dow   command
  * *   *   *   *    Display=:0.0 /usr/bin/notify-send Hey "How are you"

I checked /var/log/syslog and the command is actually executed every minute but it doesn’t pop up the notification.
Can anybody help me understand why?

Solution

I found the answer:

$ crontab -l
# m h  dom mon dow   command
  * *   *   *   *    export DISPLAY=:0.0 && export XAUTHORITY=/home/ravi/.Xauthority && sudo -u ravi /usr/bin/notify-send Hey "How are you"
