I need to enter the command line alone with no GUI to install the official NVIDIA drivers. I'm trying to get my computer to work over HDMI and someone on Youtube shows how but you have to be in the Nvidia settings program.

To do that just follow this:

  1. Go to CLI mode:

    CTRL + ALT + F1

  2. Stop GUI service on Ubuntu:

    sudo service lightdm stop

    or if you're using a version of Ubuntu before 11.10, run:

    sudo service gdm stop

    Perhaps add more Display managers, for the other variants of Ubuntu. – Uri Herrera Jun 9 '12 at 16:25

    running this from terminal sudo service lightdm stop worked for me. – razzak Dec 8 '15 at 11:53


sudo service gdm stop

to stop the GUI and

sudo service gdm start

to start it again

    If you use kubuntu change gdm with kdm :) – kv1dr May 31 '11 at 12:09
  • I'll accept yours because my question was too way specific. Actually I needed to run telinit 1 to completely disable not required processes. – dierre May 31 '11 at 12:11

If your purpose is to temporarily disable GUI - you can stop the lightdm service ( or whichever greeter you're using ) with sudo service lightdm stop (14.04 and earlier) or sudo systemctl stop lightdm (since 15.04) from tty1, as shown by others already.

If your purpose to boot into command line for extended period of time between reboots, you can open /etc/default/grub with the choice of your text editor. I personally use nano, so for me the command would be sudo nano /etc/default/grub. Now, find GRUB_CMDLINE_LINUX="" to GRUB_CMDLINE_LINUX="text". Or you can create two lines, one commented , one uncommented like so:


Once necessary, just uncomment the line for which mode you wanna enter. Upon completing editing the /etc/default/grub file, save it, and run sudo update-grub to make the configurations loaded into the actual grub.cfg file. Reboot, and you should enter the command line directly.

Start by logging out and striking CtrlAltF1, then log on.

On Kubuntu stopping the GUI can be done through sudo /etc/init.d/kdm stop. On Ubuntu this will probably be sudo /etc/init.d/gdm stop.

Enter your password when prompted.

dm stands for Display Manager, check ls /etc/init.d/ which dm is available when it is not gdm.

To restart it just change stop to start.

You probably automatically change to the GUI, if not strike: CtrlAltF7

  • obysr's lightdm sounds familiar. That would make the command: sudo /etc/init.d/lightdm stop – jippie Jun 9 '12 at 7:15

I know you are not asking this specifically, but you need to install the nvidia-current driver.

You can do this from a gui. Just run jockey-gtk or search for "Additional Drivers" from the dash. Once it is installed, open Nvidia Settings and go from there.

You could open gnome-terminal and type sudo telinit 1. This would drop you to run level 1(single user mode) and kill the gui services.

  • it's not happening. I typed sudo init 3 but nothing changed. – dierre May 31 '11 at 11:53
  • it was sudo telinit 1, then choose root. – dierre May 31 '11 at 12:08
  • @bertmanphx: you are not aware of ubuntu startup process and runlevels used. – enzotib May 31 '11 at 12:36
  • @dierre: I think it is not correct to edit answers in the core, like changing 3 to 1. This invalidates OP intentions and my objection. – enzotib May 31 '11 at 12:42

    Well the answer was actually useful so I thought to correct the wrong parts. – dierre May 31 '11 at 12:43
