About how to install and configure the fcitx Input Method In Debian locale

For details about how to install and configure the fcitx Input Method for Debian in e-file locale-Linux Release Technology-Debian, see the following. I use debian etch to call up fcitx under locale as en_US.
Gnome Desktop System.

Install fcitx and im-switch: apt-get install fcitx im-switch

If you run locale, the result is as follows:
LANG = en_US.UTF-8
LC_CTYPE = en_US.UTF-8 this line can be done if it is a zh_CN.UTF-8
LC_NUMERIC = "en_US.UTF-8"
LC_TIME = "en_US.UTF-8"
LC_COLLATE = "en_US.UTF-8"
LC_MONETARY = "en_US.UTF-8"
LC_MESSAGES = "en_US.UTF-8"
LC_PAPER = "en_US.UTF-8"
LC_NAME = "en_US.UTF-8"
LC_ADDRESS = "en_US.UTF-8"
LC_TELEPHONE = "en_US.UTF-8"
LC_MEASUREMENT = "en_US.UTF-8"
LC_IDENTIFICATION = "en_US.UTF-8"
LC_ALL =
Do not change the system locale. If the following command is not used
# Dpkg-reconfigure locales

Execute the following commands to analyze the results.
$ Ls-ahl/etc/alternatives/| grep input
$ Ls-ahl/etc/X11/xinit/xinput. d/
$ Ls-ahl ~ /. Xinput. d/
If no such file or directory appears in the last step
Then
$ Cd $ HOME to your user's HOME directory
$ Mkdir. xinput. d
$ Cd. xinput. d
$ Ln-s/etc/X11/xinit/xinput. d/fcitx en_US
Directly link

Modify file:
/Etc/gtk-2.0/gtk. immodules file, change the section about xim:
/Usr/lib/gtk-2.0/2.4.0/immodules/im-xim.so"
"Xim" "X Input Method" "gtk20" "/usr/share/locale" "en: ko: ja: th: zh
Otherwise, right-click to see whether the input method is default.

If you upgrade the system, you may have nothing to do with your/etc/gtk-2.0:
/Usr/lib/gtk-2.0/2.10.0/immodule-files.d/libgtk2.0-0. immodules
Change the xim part:
"/Usr/lib/gtk-2.0/2.10.0/immodules/im-xim.so"
"Xim" "X Input Method" "gtk20" "/usr/share/locale" "ko: ja: th: zh"
Add "en :"
OK. Log On again after logout.
Run
Im-switch-s fcitx sets fcitx as the default input method,
Now you can use ctrl + space to call up the input method. You can click the fcitx icon "smart pinyin" to switch the input.
Method (such as five strokes), enjoy!

Otherwise
Run
$ Im-switch-c
Displays available input methods for the current system.
If fcitx exists, select it.
This works with im-switch-s fcitx.
