About IME black box workaround:
1. Install the FCITX required components
$ sudo apt install fcitx fcitx-tools fcitx-config* fcitx-frontend* fcitx-module* fcitx-ui-* presage
2. Remove redundant components (for non-KDE desktops only)(FCITX does not display the candidate box solution when entering Chinese)
Because the above installation commands are installed in order to facilitate the use of wildcards, it is possible fcitx-module-kimpanel
to install one more, this component may result in non-KDE desktop environment FCITX input Chinese when the candidate box is not displayed, if the KDE desktop does not need to remove.
$ sudo apt remove fcitx-module-kimpanel
