Using FCITX to Input
Before you can make use of FCITX for input, you have to setup some environment variables. It is quite simple.
- Opening the
.profiledepending on the desktop environment and display manager you are using) file in your home directory and add following lines:
#setup XIM environment export GTK_IM_MODULE=xim export QT_IM_MODULE=xim export XMODIFIERS="@im=fcitx"
Since 4.1.0, Fcitx provides it's own input method module,, , and . It's recommend to use input method module instead of xim directly, in order to resolve strange bugs brought by XIM.
You can set corresponding environment variables
export GTK_IM_MODULE=fcitx export QT_IM_MODULE=fcitx
- Re-login to make such environment effective.
To see if fcitx is working correctly, open an application such as leafpad and press CTRL+Space(the default shortcut for switching input method) to invoke FCITX and input some words.
If everything goes well, you may want to add fcitx to your
.xinitrc file (see xinitrc) if the xdg autostart doesn't work for you:

CTRL+Space does not work
If you cannot invoke FCITX by pressing the CTRL+Space keyboard combination, but FCITX runs in background without problem, please check your locale, and make sure your locale is un-commented in /etc/locale.gen. After that it seems that by simply change LC_CTYPE to zh_CN.UTF-8 (or probably any Chinese locale) will get it done for Chinese input.
