1. Turn the Chinese interface into an English interface

Yast2->system->language: Main language: American English US

2. Log on by default with the root user

Ubuntu uses root login

Ubuntu system by default does not allow users to log in as root, although there is a certain degree of security, but does not conform to the nature of my control system. The methods found online are as follows:

1, first set the root password, using the existing administrator account to access Ubuntu, the terminal execution command: sudo passwd root, and then enter the password and root password, repeat the password. This will have the root user available.

2, the default is not allowed to log directly into the GUI with the root account. This can be done by modifying the/etc/gdm/gdm.conf file to allow root to log in directly, find Allowroot=false in the file and change it to allowroot=true switch user.

Note: In some systems gdm.conf default is read-only property, you can use sudo chmod 777/etc/gdm/gdm.conf modify file permissions before modifying
