I installed the anthy keyboard for Japanese input, and now want to remove it, but it doesn't appear in the text entry sources list.
But it still appears in the text entry sources in the upper right on the menu bar next to the time.
I tried uninstalling anthy itself using
sudo apt-get remove --auto-remove anthy, thinking that would remove it from the list, but it still is there. How can I remove this layout (so I don't have to toggle through 4 choices every time)?
