This page attempts to present an easy and simple official method to help any user set up SCIM in Ubuntu. SCIM is used to input different languages, most often Asian languages like Chinese, Japanese or Korean, but it can be used to input many other languages as well. For further explanations, please go to https://wiki.ubuntu.com/InputMethods/SCIM/Setup For Kubuntu, see Kubuntu To install im-ja, an alternative Japanese input method, please see ImJa. Note : on Ubuntu 7.10 Gutsy Gibbon and Ubuntu 7.04 Feisty Fawn, you only need to do the Quick Setup, plus one more step in case your session is not using a CJK (Chinese, Japanese or Korean) language, which would be the case of most occidental languages.

Quick setup

SCIM is the name of the program that will allow you to input a CJK language in Ubuntu. 1.#1 Open System>Administration>Language SupportFootNote(You'll need administrative rights for these kind of tasks, else ask your system administrator to install it for you.): SCIM?action=AttachFile&do=get&target=Menus.jpg 2.#2 and install the support package corresponding to the language you want to inputFootNote(You'll need an Internet connection because these packages don't fit on the Install CD.): SCIM?action=AttachFile&do=get&target=Screenshot-Language_Support.png 3.#3 under Gutsy or Feisty, you will have to check the box at the bottom (Input Method) to activate complex characters input. You will have to uncheck it, click Apply, then check it again and click Apply. 4.#4 then log out (System>Quit>Log Out), and login again. If your session is using a CJK language (for example, all you menus are in Chinese, Japanese or Korean) you should be able to input it in any application (go to Using Using SCIM to learn how to do it).

Additional configuration if you're not using a CJK session

Note : You should already be able to use SCIM input in a few applications, like gedit (Application>Accessories>Text Editor), by right clicking on the document, then selecting Input Methods>SCIM Input Method. However, it won't work in the others, like Open Office. On Gutsy, you might also notice that installing scim have broken deadkeys support - for example, you won't be able to type î, because typing the key before the i key will result in i. Do not worry, the following steps will ensure both deadkeys and scim will work together.

Under Ubuntu 7.10 Gutsy Gibbon

1.#1 Open System>Administration>Synaptic Package ManagerFootNote(You'll need administrative rights for these kind of tasks, else ask your system administrator to install it for you.) and install the package named scim-bridge : SCIM?action=AttachFile&do=get&target=Screenshot-SynapticPackageManager_scim-bridge.png Alternatively, if you prefer the command line, you can type in a terminal :

sudo apt-get install scim-bridge

If you want to use scim input in KDE applications, like Amarok or k3b, you will also have to install the package scim-bridge-client-qt using one of the two aforementioned methods (the package scim-bridge-client-gtk, for Gnome applications, should have been installed automatically along with scim-bridge). 2.#2 Edit the file /etc/X11/xinit/xinput.d/scim by typing in a terminal (Applications>Accessories>Terminal):

sudo gedit /etc/X11/xinit/xinput.d/scim

Change the line :

GTK_IM_MODULE=xim

into :

GTK_IM_MODULE="scim-bridge"

If you want to use scim input in KDE applications, you will also have to change the following line :

QT_IM_MODULE=xim

into :

QT_IM_MODULE="scim-bridge"

The resulting file will look like this: SCIM?action=AttachFile&do=get&target=Screenshot-scim-gedit.png Save the file, then to be sure you won't be affected by previous configurations you can delete the folders .scim and .xinput in your home directory. Since they are hidden folder, you can make them appear in Nautilus with the shortcut Ctrl+H. Now restart your computer and you should be done :)

Under Ubuntu versions prior to Ubuntu 7.10

The recommended method to set up SCIM input for all applications is using a command-line tool called im-switch (where im stands for Input Method, obviously :) ). Before that, you will have to know the name of the locale you're using. In a terminal (Applications>Accessories>Terminal) type :

locale | grep LANG=
The anwer would be something like
LANG=en_GB.UTF-8
where the relevant part is en_GB (en standing for English and GB for the country, here Great Britain). Another example could be fr_FR (fr for French and FR for France). Now you just have to install an additional package called 模板:Scim-qtimm and tell the system you want to use SCIM as the input method for your locale, using
im-switch -z “your locale” -s scim
In the above example, with an en_GB locale, you would type in the terminal :
sudo apt-get install scim-qtimm
im-switch -z en_GB -s scim

Log out, then log in again. SCIM should be now the default input for all applications (go to Using Using SCIM to learn how to use it) Note for Xubuntu users : On Xubuntu, the system will ask you first to install the package libapt-pkg-perl. Install it from Synaptic (see above) or by the command line :

sudo apt-get install libapt-pkg-perl

Then you'll be ready to use im-switch (see just above). In Xubuntu, you will also have to apply the following instructions :

In case all of this doesn't work

You might have to add your locale as a supported locale, by editing (you might have to create it) the file ~/.scim/global (the ~ means it's in your home directory, the . that .scim directory is a hidden file. Just type in a terminal :

gedit ~/.scim/global 

If you can find a line like

/SupportedUnicodeLocales = en_US.UTF-8

add your locale to it after a coma, not forgetting you need to add the full name reported by locale | grep LANG= after LANG= . In case of English for Great Britain, your line would look like this one :

/SupportedUnicodeLocales = en_US.UTF-8,en_GB.UTF-8 

If the line wasn't there, create it, then save the file. Log out, then log in and you should be able to use SCIM input in every application.

Binary Incompatibilities with Some Apps

Note: On Edgy (and possibly under Dapper, not tested), after making these changes, some applications (such as OpenOffice) may fail to start, or may appear to start and then simply die. If you encounter this issue, try using the "scim_xim" option for im-switch instead of "scim", for example: im-switch -z en_GB -s scim_xim Anchor(Using)

Using SCIM

SCIM should now start along with every application. To trigger it, use any of these shortcut keys : Control+space, Shift+space, Zenkaku_Hankaku(on Japanese keyboard), Hangul(on Korean keyboard) While inputting, if you want to switch back and forth between your CJK language and your session language, you can just use the shortcut key. Fast and easy! Note: If you find that the shortcut key has stopped working, check your Caps Lock status. The shortcut key for SCIM will not work if Caps Lock is turned on (this is arguably a bug).

Reverting changes

There are several ways to revert the changes performed above:

  • Use im-switch to set the input method for your locale to "default", for example:

im-switch -z en_GB -s default

  • Remove the file in your ~/.xinput.d directory corresponding to the appropriate locale:

rm ~/.xinput.d/en_GB

  • Remove the SCIM package from your system (this should not be needed, and isn't the cleanest method, but should do the job if nothing else does):

apt-get remove scim
