Fcitx Configure UI:

  1. Config Tool Wrapper:

    Found fcitx5-configtool at /usr/bin/fcitx5-configtool.

  2. Config GUI for qt:

Frontends setup:

The environment variable checked by this script only shows the environment under current shell. It is still possible that you did not set the environment to the whole graphic desktop session. You may inspect the actual environment variable of a certain process by using xargs -0 -L1 /proc/$PID/environ for a certain process that you find not working.

Xim:

  1. ${XMODIFIERS}:

    Environment variable XMODIFIERS is set to "@im=fcitx" correctly.
    Xim Server Name from Environment variable is fcitx.

  2. XIM_SERVERS on root window:

    Xim server name is the same with that set in the environment variable.

Qt:

  1. qt4 - ${QT4_IM_MODULE}:

    Please set environment variable QT_IM_MODULE to "fcitx" using the tool your distribution provides or add export QT_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: QT_IM_MODULE.

    fcitx5-qt4-immodule-probing not found.

  2. qt5 - ${QT_IM_MODULE}:

    Please set environment variable QT_IM_MODULE to "fcitx" using the tool your distribution provides or add export QT_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: QT_IM_MODULE.

    It is OK to use qt5 built-in Wayland im module if your compositor fully supports text-input protocol used by qt5.

    Using fcitx5-qt5-immodule-probing to check the actual im module to be used under current environment:

    QT_QPA_PLATFORM=wayland
QT_IM_MODULE=
IM_MODULE_CLASSNAME=QtWaylandClient::QWaylandInputContext

  3. qt6 - ${QT_IM_MODULE}:

    Please set environment variable QT_IM_MODULE to "fcitx" using the tool your distribution provides or add export QT_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: QT_IM_MODULE.

    It is OK to use qt6 built-in Wayland im module if your compositor fully supports text-input protocol used by qt6.

    Using fcitx5-qt6-immodule-probing to check the actual im module to be used under current environment:

    QT_QPA_PLATFORM=wayland
QT_IM_MODULE=
IM_MODULE_CLASSNAME=QtWaylandClient::QWaylandInputContext

  4. Qt IM module files:

    Found fcitx5 im module for qt: /usr/lib/qt/plugins/platforminputcontexts/libfcitx5platforminputcontextplugin.so.
    Found fcitx5 qt6 module: /usr/lib/fcitx5/qt6/libfcitx-quickphrase-editor5.so.
    Found fcitx5 qt5 module: /usr/lib/fcitx5/qt5/libfcitx-quickphrase-editor5.so.
    Found fcitx5 im module for qt6: /usr/lib/qt6/plugins/platforminputcontexts/libfcitx5platforminputcontextplugin.so.
    Found unknown fcitx qt module: /usr/lib/qt6/plugins/plasma/kcms/systemsettings/kcm_fcitx5.so.

    Following error may not be accurate because guessing Qt version from path depends on how your distribution packages Qt. It is not a critical error if you do not use any Qt application with certain version of Qt or you are using text-input support by Qt under Wayland.
    Cannot find fcitx5 input method module for Qt4.

Gtk:

  1. gtk - ${GTK_IM_MODULE}:

    Please set environment variable GTK_IM_MODULE to "fcitx" using the tool your distribution provides or add export GTK_IM_MODULE=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: GTK_IM_MODULE.

    It is OK to use gtk built-in Wayland im module if your compositor fully supports text-input protocol used by gtk.

    Using fcitx5-gtk2-immodule-probing to check the actual im module to be used under current environment:

    GTK_IM_MODULE=fcitx5

    Using fcitx5-gtk3-immodule-probing to check the actual im module to be used under current environment:

你字体配置有问题，建议检查 embeddedbitmap

没有改动过 embeddedbitmap，而且其他的程序都可以正常显示 emoji。

还有什么设定可能会影响这个吗？
