[SOLVED] Cannot run notify-send from cron job

leonidas · 2017-02-12 12:08:01

I have a backup script that run as root cron job:

export DISPLAY=:0
SHELL=/bin/bash
PATH=/bin:/usr/bin:/sbin:/usr/sbin

BACKUP_DIR="/run/media/leonidas/WD/backup"
LOG_FILE="/home/leonidas/backup.log"

rsync -rtvu --delete --log-file=$LOG_FILE  /home/leonidas/Documents "$BACKUP_DIR"

notify-send --icon=gtk-add "Local Backup" "WD hard disk"

This is the cron job:

45 13 * * *  /home/leonidas/backup.sh >/dev/null 2>&1

But the notify-send doesn't work. Could you provide any help please?

I have already test it.
I run from console:

sudo -u leonidas DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus notify-send 'Hello world!' 'This is an example notification.'

but it didn't work.

Sanity check: is a notification server running, i.e. does notify-send work if you run it normally?

Is XAUTHORITY set?

It works as a regular user but not as root

As root do you use the full line from post #3?

leonidas · 2017-02-12 13:40:17

Yes,

XAUTHORITY=/home/leonidas/.Xauthority

I also added it in my script with:

export XAUTHORITY=/home/leonidas/.Xauthority

but it still doesn't work

Strange, that line it works! I thought the first time that it didn't.
It finally runs from root cron job.
So the line inside my script is:

sudo -u leonidas DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus notify-send "Local Backup" "WD hard disk"

I'm glad it works. Though I don't understand the reaction. This is the second time today someone exclaimed how strange it was that the command well documented in the wiki worked.

Maybe I didn't notice the x_user or x_userid of the example...

Sorry for necropost. I was looking for a solution for the same problem and figured out how to run send-notify without sudo or su (which involves PAM and spams to journal):

# DISPLAY=:0 DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/1000/bus setpriv --euid=1000 notify-send …
