Ubuntu defaults to being unable to log on with root, which is cumbersome for individuals without the root user privileges. Here I will introduce Ubuntu Keylin 14.04 to open root login; If you need a classmate, just study together!!!
1. Set password for root user
Installation complete If you need to log in as root, you can open the terminal to enter the following command: #设置root密码sudo passwd root, enter the current user password, and then enter two times the set root password;
2, #切换到root用户sudo-S. Enter root password, enter root terminal
3, set the login panel to enable it to achieve root login
To log in using root in the login interface, edit the/usr/share/lightdm/lightdm.conf.d/50-in the/usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf directory ubuntu.conf files, such as without this file, create/usr/share/lightdm/lightdm.conf.d/50-ubuntu.conf directly into/usr/share/lightdm/lightdm.conf.d/
Edit 50-ubuntu.conf file content is final: [Seatdefaults]user-session=ubuntu
After the modification, execute the reboot command to restart Ubuntu for effective;
Automatically log in as root after startup autologin-user=root# manually enter the username and password for the login system greeter-show-manual-login=true# Disable the Guest user Allow-guest=false
4. Restart Ubuntu
The command line enters reboot carriage return, waits for reboot, and the default is logged in by the root user after startup.
Note: Learning users if the use of Vim is unfamiliar to use gedit is very convenient.
