Getting rid of annoying messages when executing a GTK+ application from the terminal
- Vous devez vous identifier ou créer un compte pour écrire des commentaires
You may have seen this message when executing a GTK+ application from the terminal:
Gtk-Message: Failed to load module "canberra-gtk-module"
And/or this one:
WARNING **: Couldn't register with accessibility bus: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.
To get rid of the first message, install "libcamberra-gtk-module", in Trisquel's repository.
To get rid of the second message, execute that command:
$ echo 'export NO_AT_BRIDGE=1' | sudo tee -a /etc/environment
Time concerns allowing, please take a look at missing icons will you.
Canberra? Seems to be an GNOME-dependent audio lib as of my slight research. But what is your desktop thanks? LXQt? GNOME? Unity shell? Cinnamon? MATE? Xfce? LXDE?
As for GNOME, Unity, Cinnamon, MATE that shouldnt be a problem, just to perform a dist-upgrade then try again.
As for LXQt, it's dependent on no libs other than Qt, use an Qt-written replacement like a few similar libs from and for Qt-written VLC.
I use GNOME but I am pretty sure Trisquel's default environment was printing those messages as well because common programs, such as 'gksu', were.
A minor detail: it should be libcanberra-gtk-module.
"...MATE that shouldnt be a problem..."
Gtk-Message: Failed to load module "topmenu-gtk-module"
##EDIT##
This error message goes away by installing package 'topmenu-gtk2'.
sudo apt install topmenu-gtk2
