I've ran across bug 711399, and the following might be the case for you, too:
It looks that you had libcanberra-gtk-module installed, but then removed it (but not purged it). This way the file /etc/X11/Xsession.d/52libcanberra-gtk-module_add-to- gtk-modules has been left, which adds canberra-gtk-module to GTK_MODULES. You can fix the (rather cosmetic) error by e.g. pruning the package: "sudo dpkg -P libcanberra-gtk-module". The real fix might be to only adjust GTK_MODULES, if the module itself (.so file) is still installed. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/689434 Title: Gtk-Message: Failed to load module "canberra-gtk-module": libcanberra- gtk-module.so: cannot open shared object file: No such file or directory To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libcanberra/+bug/689434/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
