Qt not using the system notification daemon



  • Hello!

    After switching my notifications from KDE to dunst I've started seeing Qt show these fallback notifications instead of my dunst ones.

    sample

    notify-send still works fine and shows the notifications I'd expect, and so do all GTK applications, it's only Qt that does this.

    Did anyone else encounter this problem before? I am on Arch Linux and running i3wm.

    Thanks in advance

    Hi
    Do you mean that some Qt applications does this or Qt Creator ?
    Also since all of KDE is Qt then maybe its a KDE thing?

    Hello, thanks for your response.
    All Qt applications do this.

    I removed KDE from my system which made this start happening.

    In my program outputs I get a few lines printed to output:

    DEBUG: D-Bus global menu: no
    DEBUG: D-Bus system tray: no
    

    Which did not happen back when I was running KDE.

    And as I said, everything is in theory normal. notification-send works and so do GTK applications.

    I tried running the freedesktop Notify method using the Qt5 DBus debugger, but it errored: error

    That is just about all I know about this issue, thanks again.

  • I've noticed this in the past as well. Would be nice with a fix.

    Does it work well in Gnome? If that's the case then I wouldn't consider it that important. I'm sure the Qt team knows how to allocate resources better than me.

    Hi,

    AFAIK, QSystemTrayIcon doesn't use dbus in its Linux backend. That might be related to your situation.
