为了帮助在这里绊倒的人，
您需要配置~/.XCompose（请参阅下面的完整文件）并重新启动X session。
在拉丁键盘上键入希腊字母：
- 按住撰写键-通常是正确的Alt（在“系统设置”的“键盘”部分中查找“撰写键位置”）。
<Multi_key>在下面的列表中。
- 键入g小写字母或G大写字母。G代表“ G reek”。大小写不同以方便使用
- 输入等效的拉丁字母。
- 释放撰写键。
您可以在file中看到系统范围内配置的撰写序列的列表/usr/share/X11/locale/$LANG/Compose，其中$LANG是当前语言环境的环境变量（对于美国英语，它等于en_US.UTF-8）：
$ cd /usr/share/X11/locale/$LANG/
$ less Compose
要启用希腊字母撰写功能，请添加到您的~/.XCompose文件中：

也可以使用单独的组合键组合来设置最常用的字母。例如π：
<Multi_key> <p> <i> : "π" U03C0 # GREEK SMALL LETTER PI
您还可以将此列表保存在一个名为的文件中，GreekCompose并在中使用include命令~/.XCompose：
include "%L"
include "/path/to/GreekCompose"
上面的列表是通过手动调整小型Python脚本的输出创建的：https : //github.com/rybak/scripts/blob/master/extra/gen_x_compose.py
