Imagine no user logged in to neither GUI nor CLI but a background service is running. Is it possible to send a notification to GUI after completion of the processing running on the background?

Thanks Samuel. It worked!

Use the "ps" ("ps auxw | less" is what I usually use) command to see what process is running, maybe lightdm. When you find it, you will see which user it is running as. However, I don't know which DMs support notifications.

I only ever use KDE, but my /etc/sysconfig/desktop file says: $ cat /etc/sysconfig/desktop DESKTOP=GNOME OTOH, I have: $ systemctl status sddm ● sddm.service - Simple Desktop Display Manager Loaded: loaded (/usr/lib/systemd/system/sddm.service; enabled; vendor preset: enabled) Active: active (running) since Fri 2019-09-20 10:53:31 BST; 3 days ago
