Hi,
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?
I have checked notify-send but could not find such a specific example.
Thanks in advance.
Regards,

So you want to send a notification to the gdm login screen? You can do that using the gdm user's dbus and the notify2 python library. Install "python3-notify2" and create a python script for the notification (example below). Then you can run: sudo -u gdm DBUS_SESSION_BUS_ADDRESS=unix:path=/run/user/42/bus /tmp/notif.py My test script was at /tmp/notif.py
# cat /tmp/notif.py #!/usr/bin/python3
import notify2
notify2.init("my test")
n = notify2.Notification("Hey you!", "information here") n.show()
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.

Noticed that there is dbus user not sure if its the correct one to use.

No, you need to find the display manager process. lxdm is usually the one used for lxde.

I have checked /etc/sysconfig/desktop and found that lxdm is the Display Manager

That may not be reliable. 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 ...

Which is why the accurate way to determine the DM is....
[egreshko@meimei ~]$ ll /etc/systemd/system/display-manager.service lrwxrwxrwx. 1 root root 36 Nov 5 2017 /etc/systemd/system/display-manager.service -> /usr/lib/systemd/system/sddm.service
And note where the symbolic link points

Thanks.
That confirmed its lxdm
