I had Chinese input with IBUS working for a long time. Recently the Chinese input started having some problems. When the problem occurred a week or two weeks ago, the input method works, shows the candidates, input my choices, then after a few Chinese characters, it stopped mapping my choice number into Chinese character, just put the number into the document.
But now the input method completely stopped working, doesn't even switch to the Chinese input mode.
I removed and reinstalled Chinese, IBUS, restarted so many times without any success.
What else can I do?
