yad notifications (https://sourceforge.net/p/yad-dialog/wiki/NotificationIcon/) like in this example are not displayed:

yad --notification --image="gtk-help" --command="echo 'Hello World'" --text="The notification's tooltip"

I guess it has to do with gnome shell. How can I show the yad notification?

GNOME Shell 3.34.1 Ubuntu 19.10

I used gnome tweaks to enable Ubuntu Appindicators to no effect.

  • I am currently using github.com/p-e-w/argos, a gnome shell extension which accomplishes the same thing. But yad is a great tool in general, and seems more simple, so I am interested in getting it to work.

  • Sure the syntax of your command is right? For me, the command hangs the termnal.

  • Is this a default Ubuntu session or a Gnome session?

  • @vanadium Thanks for giving it a try. Pretty sure it is correct. I expect the command to run indefinitely as it is supposed to display an app indicator as long as it is running.

  • @vanadium Not quite sure where you are going with this. I am not an expert on session managers, but I guess that I am using a gnome shell extension is not sufficient evidence? It says in the about dialogue that I am using Gnome 3.34. Please provide some guidance if that does not answer your question.

The classical "system tray" where any application could create an icon has been deprecated in various desktops since 2010. See https://ubuntu.com/blog/notification-area. A more standard notification system has been retained, where applications could, through dbus, create a notification in the notification area that acts in a more standard way for all applications.

Up to version 2.26, Gnome had a "legacy tray" area as a pop out in the bottom corner that could host such icons. Then, Gnome Shell developpers got rid of it all together. Yet, Gnome ShellExtensions such as Topicons Plus and KStatusNotifierItem/AppIndicator Support (used also in Ubuntu desktop as the "Ubuntu appindicators" extension) brought these notification icons back to the topbar. However, application icons have disappeared.

yad for its --notification option may rely on the old mechanism that is now obsolete. Therefore, the option does not work anymore on Unity desktop or Gnome Shell, even with the KStatusNotifierItem/AppIndicator enabled.

Still, the Excellent Gnome Shell extension Argos allows you to create interactive indicators in your top bar. Alternatively, use the notification system instead. In the shell, notifications can be created using notify-send.

  • None of those workarounds works any more 🙁. I shall check out Argos in the meantime.

  • … And Argos isn't compatible with Gnome 42 in Ubuntu 22.04. Ugh.

The gnome shell extension Topicons plus allow us to show icon from yad --notification https://extensions.gnome.org/extension/1031/topicons/
