I have found some solutions but what I want to do is I want to become a root user "permanently". When I restart computer I still want to stay as a root user. I don't want to use termanial everytime to become a root user. Is there any idea?
In Ubuntu 13.10 / 13.04 / 12.10 and Ubuntu 12.04, User defined login or GUI root login is disabled by default. You can enable the user defined login by modifying the lightdm configuration file. Once the manual login is enabled, then its easy to login as root in GUI.
To Enable Manual Login in Ubuntu 13.10 13.04 12.10 12.04
Open a Terminal run the following command, Issue the password for the user when prompted.
echo "greeter-show-manual-login=true" | sudo tee -a /etc/lightdm/lightdm.conf
Now set / change the password for the root user in your machine.
To set / change the root password run the following command in the terminal and issue the password for the user, when prompted.
sudo passwd
Enter the password twice. After creating the password, restart the system.
Now you can find the manual login option in the login list. Select Login and type user name as root and provide the root password which you have created.
Hope this will be helpful for you!!!
