After the installation is complete, restart the system to use Ubuntu.

Automatically log on to Ubuntu

By default, every login to Ubuntu requires a user name and password, which is based on security considerations. However, for the desktop version, everyone is used to automatically logging on to their computer, similar to Windows XP, you can use some settings to automatically log on to Ubuntu. Click System> System Management> logon window (enter the administrator password ), on the "security" option page, select (enable automatic logon) and select your username from the drop-down list. Then Ubuntu will be able to log on automatically.

Automatically run the program on Ubuntu

Similar to the Windows startup menu, some commands can be automatically run at Linux startup. the simple method is to modify the/etc/rc. local file and add the commands to be executed.

Ubuntu system desktop settings

Ubuntu desktop has two Taskbar by default, one on the top and one on the bottom. Windows users prefer to move the above to the bottom. The Ubuntu panel cannot be dragged. right-click the above and choose, it can be displayed at the bottom of the screen. The desktop background settings are similar to those for Windows. right-click "desktop" and click "Change desktop background" to modify the settings.

Change the root password in Ubuntu

The default user of Ubuntu is not the root user. we can use the root Super Administrator account through operations to obtain more permissions. First open the terminal, and then execute the following statement sudo passwdroot to modify the super administrator root password. then, you can use the su command to switch to the root user to execute some operations with higher permissions.

Hosts modification

In Windows, we need to modify the hosts file on Twitter and other websites. in Linux, there are also hosts files, which are located in/etc/hosts. you can edit and modify this file as the root user, the host name and IP address are in the same format as those in Windows. for example:
127.0.0.1 localhost
