Graphical interface switch to command line interface: CTRL+ALT+F1~F6

Command line interface switch to graphical interface: STARTX

Linux has a total of 7 runlevel to view/etc/inittab files:

0: Stop (remember not to set the Initdefault to 0, as this will make Linux unable to boot)

1: Single-user mode, just like the safe mode under Win9x.

2: Multi-user, but no NFS.

3: Full multi-user mode, standard run level.

4: Generally not, in some special circumstances can use it to do some things.

5:x11, that is, into the X-window system. Graphical interface

6: Reboot (remember not to set Initdefault to 6, as this will cause Linux to restart continuously).

Where run Level 3 is the standard console character interface mode we want to enter.

Continue to look down, you can see in 7 levels, there is a id:3:initdefault this means that each time we start the system, the default entry is the 3 level. If you want to enter the graphical interface by default, you can change it here to change 3 to 5

The Linux system supports multi-user logins and can open multiple terminals for multiuser operation at the same time. Use the TTY command to view the current terminal
