Have GUI installed but you want to just boot in text mode, not starting the GUI ?

Change one line in your “/etc/inittab” file

from:

id:5:initdefault:

to:

id:3:initdefault:

The id number will tell the OS which run-level you want it to start up in.

0 - halt
1 - Single user mode
2 - Multiuser, without NFS (The same as 3, if you don’t have networking)
3 - Full multiuser mode
4 - unused
5 - X11
6 - Reboot
