How to enable root login? in ubuntu

Posted by Hemprasad Y. Badgujar on December 11, 2013


Here you go:

sudo passwd root
sudo sh -c 'echo "greeter-show-manual-login=true" >> /etc/lightdm/lightdm.conf'

Root won’t show up as a user, but “Login” will, which is how you manually log in with users not shown in the greeter.

Rebooted and then you should be able to login as root.

Warning

While it’s possible to do, it is not recommended.

Enabling

To actually enable root logins, just do a sudo passwd -u root. This will prompt for a new root password and once you confirm it, you can start using the root account to login.

Reverting back

If you want to disable root account in Ubuntu you need to lock the root account by using the following command sudo passwd -l root

Alternatives to root login

If you want to work on a root console you can also use sudo -i.

Only do this if you know what you are doing. More information on why to stay with sudo here

Graphical version needs setting up 1st:

pkexec gnome-terminal will open a terminal with a root prompt.

passwd root will allow you to create a password for root.

Note: Running users-admin with elevated privileges no longer works because of a bug that is marked as “Won’t Fix” for security reasons. See https://bugs.launchpad.net/ubuntu/+source/gnome-system-tools/+bug/685215 for an explanation.

pkexec users-admin will open the users screen:im1
