[lubuntu-users] Issue with gtk3, DBus after upgrade to Zesty

[Guillaume Smaha]

 Hi !

After an upgrade from Yakkety to Zesty, I encountered a lot of problems
with the softwares based on gtk3 like : gedit, gtk3-demo,
software-properties-gtk, ...

When I try to execute these softwares, there is no error or output and
nothing happens.

To validate gtk2 software, I tried with **vim-gtk** (gtk 2) and it works.
I tried with **vim-gtk3 -V5** and it doesn't work ; see the output :
852: The child process failed to start the GUI
Reading viminfo file "/home/user/.viminfo" info oldfilesOpening the X
display took 1 msecTesting the X display failed


I tried with gdk and gtk debug messages **G_MESSAGES_DEBUG=all gedit
--gtk-debug=all --gdk-debug=all** :
Gdk-Message: Trying wayland backend
Gdk-Message: opening display
Gdk-Message: Trying mir backend
Gdk-Message: Trying x11 backend
Gdk-Message: visual: true color: 32
Gdk-Message: visual: direct color: 24
...
Gdk-Message: visual: true color: 24
...
Gdk-Message: GLX version 1.3 found
 - Vendor: Chromium
 - Checked extensions:
    * GLX_ARB_create_context_profile: no
    * GLX_EXT_create_context_es2_profile: no
    * GLX_SGI_swap_control: no
    * GLX_EXT_texture_from_pixmap: yes
    * GLX_SGI_video_sync: no
    * GLX_EXT_buffer_age: no
    * GLX_OML_sync_control: no



I also found another message with **gedit -w** :
Failed to register: GDBus.Error:org.freedesktop.DBus.Error.NoReply: Message
recipient disconnected from message bus without replying



So, I tried to launch **gedit** with **dbus-monitor** to see the dbus calls

But I don't know how to search deeper in dbus.

Any ideas ?


Thanks
