Then use the new Login option to manually type in the root userID and password. Restart the lightdm service with: sudo systemctl restart lightdm. Add this line: greeter-show-manual-login=true. 
Edit the /usr/share/lightdm//nf configuration file. You can configure lightdm to allow manual logins with these steps: If there were a way to make normal users have full root access, it would be the exact same process with Ubuntu as with Debian.īy default user IDs below 1000 are hidden and aren't shown on the login screen. By the content in your question, you are already familiar with the sudo, and sudo su - variations. A normal user on both OSes will have to have sudoers access to use elevated commands. You will see this usage of sudo pretty much anywhere you read a tutorial about Ubuntu on the web. For instance, to run apt-get dist-upgrade as a superuser, you could use: sudo apt-get dist-upgrade. Having the root account disabled is a layer of defense.Īs far as disabling sudo, that's not something you can do on Debian or Ubuntu. Anybody with full 'sudo' permission may perform something 'as a superuser' by pre-pending sudo to their command. Hackers run scripts to try to break into computers as root. which would be the same as logging in as root on Debian.Ī security risk (among many) to having the root account enabled it that the root account is common on all Linux systems. While it's not advisable, you could enable it just by setting up a password for it with: $ sudo passwd root As mentioned in the comments, by default on Ubuntu (which is another difference) the root account is disabled. UBUNTU SUDO SU INSTALL
The difference is that when you install Ubuntu, it'll prompt you for a username and password for logging it and add this user to the sudoers group. It seems like the second command 'su ' is to fast after prompting password query.
If you are logged in as root (which is userID 0 you will not have to use sudo for the elevated privilege, you'd already have it. Edit: This above did not work on a testing Ubuntu.
Ubuntu, which is Debian based, works the same as Debian. In Ubuntu Linux there is not root account configured by default. The short answer is, no, you can't disable it.
