安装设置SCIM

本文中的设置是根据SCIM网站的wiki，加上我自己的设置所记录的。官方网址是：

Installation of scim on Ubuntu
先安装中文包

sudo apt-get install language-pack-zh

Make sure you have the universe repository enabled.

sudo apt-get install scim-gtk2-immodule

Then install the input method engines you plan to use.

sudo apt-get install scim-pinyin

System configuration
Environment variables
Create a file called 75custom-scim_init in /etc/X11/Xsession.d
Paste the following into it:

export XMODIFIERS="@im=SCIM"
export GTK_IM_MODULE="scim"
export XIM_PROGRAM="scim -d"

It is useless to export QT_IM_MODULE="scim" because the Qt-immodule patch is not applied in Ubuntu's Qt. Therefore, scim (or skim) interacts with KDE/Qt apps via XIM protocol.

Locale configuration
Please read the System configuration section to know which locale you should use. We strongly recommand you to choose a *.UTF-8 locale.

sudo dpkg-reconfigure locales

Select the locale you have chosen as default, it may be already.
Then edit the /etc/environment file. It must include the following:

LANG=en_US.UTF-8
LC_CTYPE=en_US.UTF-8
**切记，这里不能是utf8

Where en_US.UTF-8 is to replace with the locale you have chosen.
The file must not define the LC_ALL variable !

If your locale is not en_US.UTF-8, you have to add it to scim supported unicode locales.

mkdir ~/.scim
echo '/SupportedUnicodeLocales = en_US.UTF-8,fr_FR.UTF-8' > ~/.scim/global

where fr_FR.UTF-8 is your locale.

Scim loading at start-up
Scim should be loaded when you start a Gtk application.
If you want it to be loaded automatically at start-up, go to System->Preferences->Sessions, choose Startup Programs, and add

scim -d

You can keep the order at 50.

OK，配置完成，重启X或者系统。
