If you are using xmonad then you aren't using GNOME-Shell?

That fixed it, thank you very much!

I thought gnome was shipping its own notification daemon, that's why I haven't considered installing a standalone notification daemon. Learned something new, thank you!

Install a standalone notification daemon, such as `dunst`.

I'm a little confused and can't seem to find any useful info about this. I installed xmonad via dnf and selected it via the login manager, before logging in. The issue I have is, that notifications aren't showing up at all. Is there anything left to do manually to make this work or should this work out of the box and the issue I'm having is related to something else?

Notification popups not showing up with xmonad
