I want to know if there is a way to switch to console mode from boot menu. I've NVIDIA 1070 and every time there is an update, GUI stops working. All I need to do is re-install the drivers however to do that I need console.

[EDIT]: I should have added more information to this question but I'll comment on all answers. In short: I've tried text instead of quite splash I do see booting in text more however I don't get login screen ctrl+alt+f1 doesn't help because GDM keep trying to restart. Previously I managed to kill GDM through multiple tries but is not working since latest update

[EDIT]: After searching for runlevel, I've found Change runlevel on 16.04? but I think it required me to have running system to make changes, please correct me if I'm wrong.

    Have you tried appending a 3 to the boot options (adding 3 to quiet splash)? – muru Dec 12 '16 at 2:26
  • I'll try that, so basically just change quiet splash to quiet splash 3 is that correct? – wisemonkey Dec 12 '16 at 5:47
  • Amazing thanks a lot, this is what I was looking for. I would like to know if I can somehow make NVidia (proprietary) drivers configure properly with every kernel update. But even if not this should help me. You can add it as an answer and I'll accept it. – wisemonkey Dec 12 '16 at 6:02

Yes you can. As described here (ubuntuhandbook.org - Boot into text console ubuntu) you need to edit /etc/default/grub to have the next boot end up in text mode. In summary you will set these parameters:

GRUB_CMDLINE_LINUX_DEFAULT="text"
GRUB_TERMINAL=console

After saving changes you need to run:

sudo update-grub
sudo systemctl set-default multi-user.target

Undoing text-mode

To undo sudo systemctl set-default multi-user.target simply type

sudo systemctl set-default graphical.target 
  • Is there any way to show login to terminal by default (like init 3 in old times), problem with ctrl+alt+f1 is that GDM keeps retrying to start and I don't get console. – wisemonkey Dec 12 '16 at 1:24
  • Did you try the grub method described in the answer? – WinEunuuchs2Unix Dec 12 '16 at 2:17
  • I can't login to system to edit /etc/default/grub though. – wisemonkey Dec 12 '16 at 5:53

    @wisemonkey I have updated the answer with manual updating of grub from Live DVD/USB. – WinEunuuchs2Unix Dec 12 '16 at 11:08

    This does not seem to work on Ubuntu 15.04 and up (I tried 16.04 LTS). A crucial step after you fixed the grub file and run update-grub is to execute: sudo systemctl set-default multi-user.target - only then it started booting straight into console for me. Solution from @yury in the comments of the link you gave. – f055 Sep 20 '17 at 14:41

Boot into recovery mode

Boot the computer from an Ubuntu live USB, and after the BIOS screen, hold down the left Shift key. You will then be prompted by a menu that looks something like this:

enter image description here

The timing when to hit the left Shift key can be tricky, so sometimes if you miss it you need to try it again.

Hit the down arrow until you select the 2nd entry from the top (the one with the recovery mode in the description) and then hit Enter.

Now you should see this menu:

enter image description here

Using the arrow keys scroll down to root (the second entry from the bottom in the Recovery Menu) and then hit Enter.

You should now see a root prompt and you can run commands from it.

lightdm is called lightdm because it is a lightweight application compared to GDM which is heavy and takes longer to load. If you still have lightdm installed you can switch back to using lightdm as the default login display manager with the command: sudo dpkg-reconfigure gdm. This will open up a new window allowing you to select either gdm or lightdm as the default login display manager.

Reboot the computer with the command sudo reboot

After that the keyboard shortcutCtrl+Alt+F3 may start to work properly, and allow you to start Ubuntu from the console.

Start Ubuntu from the console

  1. Open a text-only virtual console by using the keyboard shortcut Ctrl+Alt+F3.

  2. At the login: prompt type your username and press Enter.

  3. At the Password: prompt type your user password and press Enter.

  4. Now you are logged in to a text-only console, and you can run terminal commands to reinstall the NVIDIA driver from the console. To reboot the system after you reinstall the NVIDIA driver run the command: sudo reboot. Press the keyboard shortcut Ctrl+Alt+F7 to exit the virtual console. In Ubuntu 17.10 and later press the keyboard shortcut Ctrl+Alt+F2 to exit from the virtual console.

  • I replied to your comment by editing my answer. – karel Dec 12 '16 at 2:07
  • Thanks Karel, but this assumes I can get system running somehow. Is that correct? Is there a way to issue sudo dpkg-reconfigure gdm without logging in? – wisemonkey Dec 12 '16 at 5:49
  • This does not waor anymore sudo dpkg-reconfigure gdm-> package gdm is not installed(ubuntu 16.04). And sudo dpkg-reconfigure lightdm does not do anything. – Robert Mar 30 at 12:44
  • @Robert You are partially right. The reason why I referred to gdm is that gdm is mentioned in the question, therefore I was required to address it in my answer. However if you run the command apt policy gdm in Ubuntu 16.04 you will see that gdm is indeed a package in the default Ubuntu 16.04 repositories. – karel Mar 30 at 12:48

Press CTRL+ALT+F1 or any other function (F) key up to F7, which takes you back to your "GUI" terminal. These should drop you into a text-mode terminal for each different function key.

Otherwise you can boot into recovery mode if you need:

https://wiki.ubuntu.com/RecoveryMode

Basically hold down SHIFT as you boot up to get the Grub menu.

  • (copying previous comment): Is there any way to show login to terminal by default (like init 3 in old times), problem with ctrl+alt+f1 is that GDM keeps retrying to start and I don't get console. And for recovery mode its same results if I say clean start. I'll read up on other recovery modes and see if they are helpful – wisemonkey Dec 12 '16 at 1:26
