display window manager

基本解释

GNOME 3 introduces “GNOME Shell”, a new window display and activities management interface that uses the Mutter compositing window manager.
GNOME 3引入"GNOME SHELL",一种新的窗口展示，灵活的管理界面使用了Mutter（支持3D动效的窗口管理器）合成窗口管理。
To do this, you'll probably have to omit the runlevel 5 X display manager and login window; instead, log in on a console and start X yourself.
为此，很可能必须省略 runlevel 5 X 显示器管理器和登录窗口；但是可以在控制台上登录，并自己启动 X。
For most Linux users, the X Window System (or "X11", but properly speaking not "X Windows") is probably just the API that their window manager calls to display GUI applications locally.
对于大多数 Linux 用户而言，X Window 系统（或“X11”，但正确地讲不是“X Windows”）可能只是其窗口管理器为在本地显示 GUI 应用程序而调用的 API。
