I have recently upgraded from 13.04 to 13.10 development branch via update-manager. While most of the things run well, but apparently the text-input system is changed in this coming release. It actually worked quite well at first, but I just screwed up the system and decided to start with a new user account, then the input system went broken. Before this I used iBus to input chinese (ibus-pinyin), however in 13.10, after entering the pinyin the candidates failed to show up.
I tried running ibus-setup but apparently that wouldn't work anymore. Just out of curiousity, has Ubuntu changed the input method framework or something? Because there seem to be no way at the moment to change the settings besides the (new?) "Region & Language" applet (there's nothing much to change anyway). I even tried playing with the settings in ibus-setup utility but doesn't seem to have any effect. And is the Language support applet being deprecated?
