GTK DEBUG message from every app. lazarus / 32-Linux ---------------------------------------------------------------------- dbannon · 2018-08-11 07:02 Since I updated my OS to Ubuntu Mate 18.04 I see an debug message  like this on the console - Quote[DEBUG] Name com.canonical.AppMenu.Registrar does not exist on the session bus Its there in the simplest Lazarus project, one form, no other components. Now, its not a Lazarus/FPC message, its GTK  - Code: [Select]$ strings /usr/lib/x86_64-linux- gnu/gtk-2.0/modules/libappmenu-gtk-module.so | grep "does not exist on the session bus" Name %s does not exist on the session bus Apart from reporting it to GTK, any thoughts ?  I guess I'm not the only one to see it ? The message itself is in both the gtl2 and gtk3 library but of course, I don't know if its been left turned on in gtk3. I assume any report I make to gnome will be "use GTK3" ! I'm using Lazarus 1.8.4 built from SVN. Davo ---------------------------------------------------------------------- Rovert · 2019-05-19 17:21 The reason is not actually GTK or gnome. The message GTK [DEBUG] Name com.canonical.AppMenu.Registrar does not exist on the session bus is because ubuntu switched from unity to gnome. ---------------------------------------------------------------------- giahung1997 · 2019-05-19 18:59 Quote from: Rovert on May 19, 2019, 07:21:16 pmThe reason is not actually GTK or gnome.

And he's using the Mate flavor of Ubuntu but not Ubuntu itself. https://en.m.wikipedia.org/wiki/MATE_(software)
