Linux study Note 3: reinstall and install chrome

*************************

Reinstall Linux

*****************************

 

I found that Ubuntu sometimes failed inexplicably, so I decided to reinstall it.

I re-installed it once yesterday. During the re-installation process, if the new Linux is returned to the original partition instead of deleting the old partition and re-partitioning, in this way, the original Linux files will be retained in the reinstalled Linux, which is equal to not being reinstalled! Therefore, when you reinstall Linux, you must delete and repartition the original partition.

 

 

 

*************************

Install chrome

*****************************

 

It turns out that Chrome can be successfully installed only after logon with a Super User. Otherwise, normal users will not respond after opening the chrome Installation File.

 

The same is true for flash plug-ins installed with Firefox.

How to Use reboot and other commands in Ubuntu

*****************************

 

By default, Ubuntu has locked the root user, that is, the user cannot Log On As a Super User.

 

 

Default Root Account is locked under Ubuntu Linux. therefore, you cannot Login as root or use 'Su-'command to become a superuser. to run all administrative command use sudo command. sudo allows a permitted user to execute a command as the superuser or another user. ubuntu setup your default account (the one created during installation) to run all administrative commands.

For example create a new user called bar, you need to type sudo command as follows:

$ sudo adduser bar


Password:

 

Therefore, to use the reboot command, you must log on as an administrator, enter sudo reboot in the command line, and enter the administrator password.

Oh, Ubuntu is.

There is a question: how can I enable ibus to start after each system startup?

********************

Ubuntu
After the system is installed, the ibus input method is provided. It is not enabled by default in the English environment.

You can configure the Automatic startup of ibus on Ubuntu
Choose system-preferences-startup applications from the system menu, and add a program in this window:

 

Name: ibus-daemon

Command: ibus-Daemon-D-X-R
