I'm running MATE on Ubuntu 18.04 and I do not have the Dictionary listed in my Applications > Accessories menu. I do however have Artha, which is useful but not what I want.
When entering mate-dictionary
into the command line the following appears:
Gtk-Message: 07:21:55.447: Failed to load module "topmenu-gtk-module"
Then the dictionary opens and functions as expected.
I would like to have the dictionary available from the GUI rather than having to access the terminal each time.
Any help would be appreciated. Hal.
