Fedora有很多值得学习的地方，这里我们主要介绍Fedora switchdesk Gnome和KDE桌面切换，等方面。

1.在XWindows环境中，使用Desktop switch tools来切换。

2.如果是在字符环境下，用命令switchdesk KDE 或Fedora switchdesk Gnome可以将桌面切换成 KDE 或 Fedora  Gnome的。我看了一下，这两种方式其实都是在修改$HOME下面的.Xclients-default文件。如果是Gnome, 则文件内容为 exec gnome-session 如果是KDE, 则文件内容为 exec startkde

小技巧：利用此脚本，你还可以同时在一台机子的七号及八号虚拟控制台上运行两个完全不同的X-Window  Manager。

# xwin This script display a text menu and allow you to select
# which X-Window Manager you want to use

# Backcup your $HOME/.xinirtc file while run this
