I have recently upgraded Ubuntu 18.04 to 20.04. In the settings, my default input method is German.
I added the "Chinese Intelligent Pinyin" input method and it mostly worked as expected. But an issue remains: it still uses the German keyboard layout in Pinyin mode, i.e., when I press y, I get a z and vice versa.
How can I change the base layout of the Pinyin input method to English/Chinese?
