以下是引用Wengier在2003-7-22 8:22:35的发言：
大家知道，Linux是字符型界面的仿Unix操作系统，而Linux Desktop是它上面的一个GUI程序，就像Win9x那样。今天我在VMWare中装了Red Flag Linux 4.0，装好后它自动启动到了Linux Desktop下。但我同时却发现不知道怎样才能回到Linux状态下：不仅Linux Desktop的开始菜单中没有“Linux窗口”的快捷方式，而且“关机”中也找不到“退回Linux”这一项，而且由于运行速度很慢，导致操作很不方便。而且一些程序（如DOSEMU等）好像是不能在Linux Desktop这个GUI中运行的（运行会无效），似乎必须要回到纯Linux状态中才行。请问，如何从Linux Desktop中回到纯Linux下？
6.1.2 Using Virtual Consoles with X
Even while X is running, you can access the Linux virtual consoles. To switch from graphical mode to a virtual console running in text mode, type Ctrl-Alt-F n, where F n is a function key and n is the number of the desired virtual console. X uses virtual console 7, so only virtual consoles 1-6 are accessible while running X.
To switch from a virtual console back to X, type Alt-F7. Nothing is lost when you switch from X to a virtual console or back, so you can move freely between the graphical and text operating modes.
6.1.3 Terminating X
As you learned in the previous chapter, you can terminate X by typing Ctrl-Alt-Backspace. X immediately terminates each program running under X, closes each open window, and returns your system to text mode.
This key sequence terminates X abruptly; most window managers support gentler ways of terminating X. You'll learn about these later in this chapter.
While X is running, you cannot use the Ctrl-Alt-Del sequence to reboot your system. To reboot your system, you can terminate X and then use the Ctrl-Alt-Del sequence, or access a terminal window and enter the command:
shutdown -r now
The shutdown command terminates X and then reboots your system.
