Fcitx5
Fcitx 5 is a generic input method framework.
See portal site
Keyboard
for general keyboard input topics.
Package status
Package status for all Fcitx5 related source packages
It only has been packaged on bullseye and later. For buster and before, please use
fcitx
, aka fcitx4.
Install Fcitx5 on bullseye
For Simplified Chinese users
Install
fcitx5
and
fcitx5-chinese-addons
. Then logout and login again in your desktop environment. The input methods are not added to fcitx immediately. You need to configure it manually. You can run fcitx5-configtool from terminal or system tray.
apt install --install-recommends fcitx5 fcitx5-chinese-addons
Be sure to install recommended packages, it works for most people. But if you want a minimal set of packages to install, try (for KDE user):
apt install --no-install-recommends fcitx5 fcitx5-chinese-addons fcitx5-frontend-gtk3 fcitx5-frontend-qt5 fcitx5-module-xorg kde-config-fcitx5 im-config
im-config
is used to automatically configure the required environment for input methods.
For Traditional Chinese users
You can install
fcitx5-chinese-addons
too, it provides table method. But you can also install
fcitx5-chewing
for zhuyin.
For Japanese users
Install
fcitx5
and
fcitx5-mozc
fcitx5-skk
, and remove
uim
and
uim-mozc
apt install --install-recommends fcitx5 fcitx5-mozc
apt remove uim uim-mozc
or
apt install --install-recommends fcitx5 fcitx5-skk
apt remove uim uim-mozc
For Korean users
Install
fcitx5
and
fcitx5-hangul
apt install --install-recommends fcitx5 fcitx5-hangul
Other languages

GNOME
Gnome users should install
gnome-shell-extension-kimpanel
Fcitx5 works on Wayland, so you don't need to switch to Xorg.
Please notice that GNOME will install iBus regardless, you can switch the input method with im-config.
KDE
KDE users must also install
kde-config-fcitx5
. And see also known issue.
Theme
Except the builtin theme, currently there's extra one available.
fcitx5-material-color
. See the screenshots at
upstream
You can configure theme through "Fcitx 5 Configuration" -> "Configure addons" -> "Classic User Interface" -> "Theme".
Migrate from fcitx4
Install
fcitx5-config-qt
, then open "Fcitx 5 Migration Wizard" from desktop menu. If you want to migrate pinyin and table data from fcitx4,
libime-bin
is also needed.
Known Issues
The fcitx icons in KDE Breeze, Papirus are not applied.
976603
Can't input in some proprietary Qt software.
Because these software don't include fcitx5 modules in their embedded Qt library. Usually they only include fcitx4 modules.
Fcitx5 supports the old fcitx4 modules as well. But to use it successfully on these proprietary Qt software, the
QT_IM_MODULE
should be set to
fcitx
. However im-config set it to
fcitx5
977203
The solution is to modify the environment before running these software, for example run
export QT_IM_MODULE=fcitx
first.
