Modify the ubuntu14.04 command line startup

Method 1:

Originally want to not enter Xwindows by default, just edit the file "/etc/default/grub",
Put grub_cmdline_linux_default= "Quiet splash"
Change to grub_cmdline_linux_default= "quiet splash Text"
That is, add "text" after the Grub_cmdline_linux_default entry),
Then run "sudo update-grub".

Method 2: Primarily to modify the contents of a file:

cat/etc/x11/default-display-/USR/SBIN/GDM

This shows the default content of the original file, if you want to go directly to the command line mode to comment out the/USR/SBIN/GDM, and add the new content false, the following is the modified content

cat/etc/x11/default-display-Manager  #/USR/SBIN/GDM  false

So modified, reboot, you will find that the graphical interface has not come out, but directly into the command line mode, if you want to enter the GUI again, or in the command line mode input startx, you can.

Note: Method 1 verification can be used, the first time to re-login no, the second time from the command line started ...

Method 2 is not validated
