Follow these steps in the configuration:
- Choose your keyboard (here a default 104 US keyboard)
- If you want the !AltGr key replacement, choose one
- Choose which key you would like your compose key to be mapped to. I use the right logo key.
  I'd much rather like to use the left logo key, but that's not available in the console setting. But in the graphical window environment (KDE Plasma) that is possible.
- Choose the console's encoding, set it to UTF-8
- Choose what character set should be available on the console. I use Combined - Latin; Slavic Cyrillic; Hebrew; basic Arabic
  I guess that selection should give me the wanted characters.
- Choose what type of console output you'd like (do whatever you like, to be safe you can go with the given current defaults)
- A new initial RAM disk for the next boot will be created now.

KDE 3.x 设置

现在我们继续，设置我们的窗口环境（Plasma）。这里用的是Kcontrol或叫 Kubuntu 配置工具，打开的是一样的设置对话框。

启动 系统设置（System Settings）或叫KDE 控制中心（Control Centre）
区域和语言（系统设置）或区域和辅助功能（控制中心） -> 键盘布局
选择你的键盘布局
修改Xkb 选项，选择/启用compose key

KDE SC 4.x 设置

现在我们可以继续，设置我们的窗口环境（Plasma）。这里的描述中用的是系统设置（System Settings），通常能在 Kickoff 菜单中找到：

打开 系统设置
地区和语言
选择键盘布局设置项
在布局标签页，选择启用键盘布局
修改高级选项，选择/启用compose 键

设置 Gtk 程序（Gnome，FireFox 等等）

Gtk（例如 Firefox）和 Gnome 程序（Ubuntu 系统上）通常使用SCIM作为输入法，而非那种依赖(X)Compose 配置的XIM （X Input Method）。Therefore, you will often find that the "a" and "o" macron characters can yield the female/male ordinals "ª" and "º". 为了使其能同样有效，需要"告诉" GTK 程序使用 XIM。

"One Off" Configuration

对于单个程序，你可以这样做：只要设定程序的环境变量GTK_IM_MODULE值为xim：

$ GTK_IM_MODULE=xim firefox

对于单个 shell 会话永久的设置可以这样：

$ export GTK_IM_MODULE=xim

这条变量设置可以放到~/.bash_profile来设定单个用户下的G系程序都是如此，或是放到/etc/environment来设定全部用户都是如此。这种做法并怎么好，更好的方法在下面。

Persistent Configuration

Copy the setup file /etc/X11/xinit/xinput.d/default to /etc/X11/xinit/xinput.d/xim

$ sudo cp /etc/X11/xinit/xinput.d/default /etc/X11/xinit/xinput.d/xim

Edit the file /etc/X11/xinit/xinput.d/xim and set the input method for GNOME and KDE to xim

...
 GTK_IM_MODULE=xim
 QT_IM_MODULE=xim
 ...

Create a link for the locale all_ALL (or the desired locale only):

$ sudo ln -sf /etc/X11/xinit/xinput.d/xim /etc/X11/xinit/xinput.d/all_ALL

If you are using a Debian-derived distribution use following instead

$ sudo update-alternatives --verbose --install /etc/X11/xinit/xinput.d/all_ALL xinput-all_ALL /etc/X11/xinit/xinput.d/xim 20

After a restart of the X server everything should work.

可选的 XCompose Map 调整

既然你当前用 XIM，你可以进一步调整 XCompose 输入映射便于输入更多字符，或是调整键位安排方便输入等等。

照下面这样做：

创建一个~/.XCompose文件，复制下列字段进去：

# ~/.XCompose
 # This file defines custom Compose sequences for Unicode characters

# Import default rules from the system Compose file:
 include "/usr/share/X11/locale/en_US.UTF-8/Compose"

# To put some stuff onto compose key strokes:
 <Multi_key> <minus> <greater> : "→" U2192 # Compose - >
 <Multi_key> <colon> <parenright> : "☺" U263A   # Compose : )
 <Multi_key> <h> <n> <k> : "hugs and kisses" # Compose h n k
 <Multi_key> <less> < p> : "< p></p>" # Compose < p

Just log out and in again (no restart necessary), and you can use your new "multi key short strokes" using the compose key to your desire. As you see this even works for creating longer character sequences.

Typing Macrons, Umlauts, Accents, ...

The compose key will be now whatever you have configured it to be, e. g. right logo.

Macrons

compose + shift + hyphen then <vowel >

or

compose + underscore then <vowel >

-->

āēīōū ĀĒĪŌŪ

Umlauts

compose + shift + <single quote> then <vowel >

or

compose + <double quotes> then <vowel >

-->

äëïöü ÄËÏÖÜ

The German Ess-Zet ligature

compose then s and s (twice the "s")

-->

ß

More bindings can be found in /usr/share/X11/locale/en_US.UTF-8/Compose
