XFce 4设置管理器提供了对所有 XFce 4 组件进行设置的途经。该程序由两个部分构成。The settings manager dialog, which is the only part a user should need to know about, and the settings manager backend that talks to the XFce 4 programs and informs them of changes to the preferences.
On a technical note, the settings manager backend uses an the XSETTINGS protocol as defined on freedesktop.org, adapted to allow multiple channels, so a module can listen only to changes it is interested in; The mcs in the name stands for multichannel settings.
首先，你可以从XFce 4面板来打开。There is a launcher on the panel in the default configuration. If you want you can also add a special setup button that is part of the Systemsbuttons item.

另外，你可以用右键点击 (或者Shift＋点击)该面板的移动手柄，并选择popup菜单的"Settings manager"选项。
The root window menu provided by the XFce 4 Desktop Manager (xfdesktop) contains an entry to open the settings manager dialog. Right-click on the desktop background and choose All Settings in the Settings sub-menu.

The XFce 4 Settings Manager dialog provides centralized access to the preferences of all installed XFce 4 components. They don't necessarily have to be running.
Just click on the button corresponding to the module that you want to configure. This action will open a new properties dialog. Usually, all modifications will have an immediate effect on the behaviour of the selected module (instant apply). Once you have finished changing the options, you can close the dialog by clicking on the Close button. Note that there is no Cancel; if you change your mind about a setting you will manually have to change it back.
Please refer to the manuals of the different XFce 4 components to learn more about their configuration options.
Settings Manager Backend
The xfce-mcs-manager application should be started before the other XFce 4 components. In fact, the panel and the windowmanager both will try to run the manager if it is not already running.
The startxfce4 script provided with XFce 4 (part of the xfce-utils package) takes care of running it at the start of an X session. If you don't use that add it to your ~/.xinitrc file. The manager will run in the background after it has initialized, so there is no need to add an '&' after the command.
After installing a new package that provides a settings dialog, you can make the manager reread its configuration by sending a SIGUSR1 signal:
$ killall -USR1 xfce-mcs-manager
