Using dbus-send in Cron [duplicate]

  • 772

I want to setup a cron job to lock my session every day at three PM. When I enter dbus-send --type=method_call --dest=org.gnome.ScreenSaver /org/gnome/ScreenSaver org.gnome.ScreenSaver.Lock in a terminal window, the session locks immediately, but when I do the same in crontab (even by using a BASH script) it didn't work. I want to create a BASH script to lock the session using dbus-send and add it to crontab.

gnome scripts bash cron dbus

  1. Using loginctl to lock your desktop screen from crontab.

    /opt/bin/lock-session.sh:

    #!/bin/bash

# crontab -e
# min hour dom month dow command
# 0 15 * * * /bin/bash -c /opt/bin/lock-session.sh

# Display     (is the first value of Sessions).
# Sessions    (array of sessions).
property=Sessions

for session in $(loginctl show-user $USER -p $property --value); do
    [[ \
    $(loginctl show-session $session -p Desktop --value) ]] && loginctl lock-session $session
done

exit 0
