Configurable Menu is a Cinnamon Menu I installed on my desktop installation of Linux Mint 17.1, which I just upgraded to Linux Mint 17.2. It’s a menu I like because the dimensions can be adjusted, hence the name.
After the upgrading to Linux Mint 17.2, which included upgrading the kernel, the menu would not open, either by clicking on it or using the corresponding key on the keyboard. Even right-clicking would not bring up the content menu.
Not good, and searching the Internet didn’t help. Attempting to launch it from the terminal only produced the output shown in the code block below.
/usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py:50: RuntimeWarning: You have imported the Gtk 2.0 module. Because Gtk 2.0 was not designed for use with introspection some of the interfaces and API will fail. As such this is not supported by the pygobject development team and we encourage you to port your app to Gtk 3 or greater. PyGTK is the recommended python module to use with Gtk 2.0 warnings.warn(warn_msg, RuntimeWarning)
The only solution I could come up with, was to remove the Configurable Menu and switch back to Cinnamon’s default menu. That’s not a good fix, but at least I have a working menu.
