Today, I finally figured out how the Linux input method is going to work __linux

My desktop environment is KDE. Last installed Sogou Input method can not be used, and today again installed back. After some toss, roughly understand the logic of the Linux input method.
Linux Chinese input methods are dependent on the input method framework, where the framework has such as IBUs or FCITX, and so on. In the KDE "Input method" (Input im in the program search box) The Setup item should first select which frame the system enables, and then you need to select which input method to enable in the setup of this framework, and switch shortcut between different input methods.

Take Fcitx's Sogou input method to start as an example:
First step, frame selection settings

The second step, Fcitx Input Method frame Setup

The third step, Sogou Input method has been enabled after the personality settings
