Two. The situation of the system in the virtual machine

ctrl+alt+shift+f1~6 switch to the command line interface; Return to the graphical interface using ALT+F7

(Note: After the above method switch, the graphical interface does not close)

Three. Command mode modification

Open the terminal, type init 3, and enter.

The meaning of the number after Init:

 0-halt (do not set Initdefault to this)   //Downtime (don't set Initdefault to zero 0 because this will make Linux not start)
 1-si Ngle User mode                     //in Single-user mode, just like the security mode under WinXP
 2-multiuser, without NFS (the same as 3, if you don't have NETW orking)     //multiuser, but no NFS
 3-full multiuser mode                 //Full multiuser mode, standard operating pole, command line interface
 4-unused          //generally not, but in some special cases you can do something with him.
 5-X11                /Select this, the system will enter the graphical login interface when logging in
 6- Reboot (do not set Initdefault to this)    //reboot (don't set the Initdefault to 6 because this will keep Linux from restarting)
(note: After switching the above method, The graphical interface is completely closed. If there are files in the window that are not saved, they will be lost. You can return to the graphical interface with Init 5, but the original process is dead. Load the graphical interface at current level 3 with StartX)
