Fcitx5 theme options not shown in KDE Plasma settings

Orange-Icepop · 2025-11-09 08:36:56

After installing and configuring fcitx5, I installed a few fcitx5 themes from AUR, such as "fcitx5-theme-macos12", and the files are properly placed under /usr/share/fcitx5/themes/, but only two default themes are shown in kde settings:
fcitx theme on kde
I use KDE Plasma, running on Wayland.

You did install fcitx-kcm ? see https://wiki.archlinux.org/title/Fcitx# … tion_tools

Sadly, the two config tools both rely on fcixt4, conflict to the fcitx5 that I've installed.
Any other solutions? Or fcitx5 exactly doesn't support configuring themes through GUI?

It appears fcitx5 has it's own page , https://wiki.archlinux.org/title/Fcitx5 .

check section 2.1.12 .

This is the result of fcitx5-diagnose(translated from chinese). Note that I'm using KDE+Wayland, and it's not recommended by Plasma to set the GTK_IM_MODULE and QT_IM_MODULE variable.

# Frontend Setup:
The environment variables checked by this script can only show the environment of the current command line. It is still possible that your environment is not applied to the entire desktop. You can check the actual environment variables of a non-functioning process by using the command `xargs -0 -L1 /proc/$PID/environ`.

## Xim:
1. `${XMODIFIERS}`:

**The value of environment variable XMODIFIERS is set to "@im=fcitx5" instead of "@im=fcitx". Please check if you have incorrectly set its value in some initialization file.**

**Please use the tools provided by your distribution to set the environment variable XMODIFIERS to "@im=fcitx" or add `export XMODIFIERS=@im=fcitx` to your `~/.xprofile`. See [Input method related environment variables: XMODIFIERS](http://fcitx-im.org/wiki/Input_method_r … XMODIFIERS).**

The Xim service name obtained from the environment variable is fcitx5.

2. XIM_SERVERS on root window:

**Xim service name: "fcitx" differs from the value set in the environment variable: "fcitx5".**

## Qt:
1. qt4 - `${QT4_IM_MODULE}`:

**Please use the tools provided by your distribution to set the environment variable QT_IM_MODULE to "fcitx" or add `export QT_IM_MODULE=fcitx` to your `~/.xprofile`. See [Input method related environment variables: QT_IM_MODULE](http://fcitx-im.org/wiki/Input_method_r … _IM_MODULE).**

**`fcitx5-qt4-immodule-probing` not found.**

2. qt5 - `${QT_IM_MODULE}`:

**Please use the tools provided by your distribution to set the environment variable QT_IM_MODULE to "fcitx" or add `export QT_IM_MODULE=fcitx` to your `~/.xprofile`. See [Input method related environment variables: QT_IM_MODULE](http://fcitx-im.org/wiki/Input_method_r … _IM_MODULE).**

**If your compositor fully supports the text-input protocol used by qt5, you can also use Qt5's built-in Wayland module.**

Using fcitx5-qt5-immodule-probing to check the input method module that will actually be used in the current environment:

QT_QPA_PLATFORM=wayland
QT_IM_MODULE=

3. qt6 - `${QT_IM_MODULE}`:

**Please use the tools provided by your distribution to set the environment variable QT_IM_MODULE to "fcitx" or add `export QT_IM_MODULE=fcitx` to your `~/.xprofile`. See [Input method related environment variables: QT_IM_MODULE](http://fcitx-im.org/wiki/Input_method_r … _IM_MODULE).**

The following errors might not be accurate, as guessing the Qt version corresponding to the path depends on how the distribution packages Qt. If you do not use any programs of the corresponding Qt version, or use Qt's text-input support under Wayland, the following errors are not critical issues.
