Problem Description:

After sudo apt get install IBus Pinyin, pressing the shortcut key Ctrl + space cannot switch between Chinese and English. Even if Chinese pinyin is activated in input method settings, it still has no effect

Solution:

First, other input methods can be used

Second, open the terminal, input IBus list engine, press enter, and print out all the input engine information of IBus. Check whether there is a language: Chinese Pinyin – Pinyin engine. If there is, enter IBus engine pinyin to switch to Chinese Pinyin input. However, the input method icon is not displayed in the notification bar. Enter IBus engine xkb:us : eng can switch to English input again. Every time you log in to the system or restart IBus, the default is xkb:us ::eng。
