What is GTK Module?

The error “Failed to load module ‘unity-gtk-module’” occurs when the GTK module for Unity is not installed or not functioning correctly. The “unity-gtk-module” is a specific GTK module that provides integration between GTK-based applications and the Unity desktop environment in Ubuntu.

Unity is a graphical user interface (GUI) that is used in some versions of Ubuntu as the default desktop environment. The “unity-gtk-module” provides a seamless integration between GTK-based applications and the Unity desktop, including support for Unity’s global menu bar and window controls.

When a GTK-based application such as Octave is launched, it may look for and try to load the “unity-gtk-module” to ensure that it is properly integrated with the Unity desktop environment. If the module is not installed or is not functioning correctly, the application may display an error message indicating that it failed to load the module.

The Command

To resolve the issue, you can try installing the “unity-gtk2-module” package. Open the terminal and run the following command: 

sudo apt-get install unity-gtk2-module

This should resolve the issue and allow you to launch software without encountering the error “Failed to load module ‘unity-gtk-module’”.
