Comment 17 for bug 1241309

I discovered how to switch the keyboard layout and other preferences in Ubuntu 13.10.

Here is what I did -
1. sudo apt-get install ibus-clutter ibus-qt4 (not sure if this step is necessary, but I noticed these two were missing with my Ubuntu 13.10 install, even after enabling ibus-chewing)
2. log out and log back in using gnome-shell (granted not everyone installs gnome-shell, but I did and it's the only way I found so far)
3. you should see input method icon on top gnome panel, next to speaker icon
4. click on input method icon and select another method (e.g. bopomofo or chewing)
5. click on the same input method icon again and you'll see Preference (for bopomofo) and Settings (for Chewing) !!!!
From what I can tell, you can also do the same for bopomofo without gnome-shell, by executing the following command -
python /usr/share/ibus-pinyin/setup/main.py bopomofo

Hope this helps,
