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:

${XMODIFIERS}:

XMODIFIERS is not set

Please set environment variable XMODIFIERS to "@im=fcitx" using the tool your distribution provides or add export XMODIFIERS=@im=fcitx to your ~/.xprofile. See Input Method Related Environment Variables: XMODIFIERS.
Xim Server Name from Environment variable is fcitx.
XIM_SERVERS on root window:

Xim server name: "ibus" is different from that set in the environment variable: "fcitx".

Qt:

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.
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

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-i 8000 mmodule-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
```

Found unknown fcitx qt module: /usr/lib/office6/qt/plugins/platforminputcontexts/libfcitxplatforminputcontextplugin.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:

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.
