How to set root permission to log in in ubuntu

How to set root permission login in ubuntu, I believe many inexperienced people are helpless about this, for this reason this article summarizes the causes and solutions of the problem, through this article I hope you can solve this problem.

1. First set the root password, log in to Ubuntu using the existing administrator account, execute the command sudo passwd root on the terminal, then enter the password and root password, and repeat the password. This will give you root users.

2. By default, it is not allowed to log in to the GUI directly with the root account. This can be done by modifying the vi /etc/lightdm/lightdm.conf file to allow root to log in directly

Add greeter-show-manual-login=true allow-guest=false . The entire modified configuration file is

[SeatDefaults]

greeter-session=unity-greeter

user-session=ubuntu

greeter-show-manual-login=true #Manually enter the login username and password

allow-guest=false #guest logins are not allowed

Restart ubuntu, login window will have "login" option, then we can log in through root.

If the above method still cannot be solved, then follow the following method:

Modify the/etc/pam.d/login file:

The code is as follows:

gedit /etc/pam.d/login

find

The code is as follows:

auth [success=ok new_authtok_reqd=ok ignore=ignore user_unknown=bad default=die] pam_securetty.so

Modify to read as follows:

The code is as follows:

auth requisite pam_securetty.so

After doing the above, restart the computer. At this point, the root user can log in to the computer.
