I. During installation, you are asked to enter the name and password for replacing the root user.

When you use sudo root to switch to the root user, you are required to enter the password. At this time, nothing is wrong.

To use the command, set the password for the root user. The command is as follows:

Sudo passwd root

Enter the password twice.

Log out and use another user to log in.

7. decompress the file

 

Install the rar decompression file:

Open the terminal and enter the following command:

Sudo-s-H (allows users to switch to the highest root permission)

Enter your User Password

Then enter the command:

Sudo apt-get install rar

Wait until the installation is complete!

Here you can use the command:

Man rar

To view the details of the rar command, if rar files need to be decompressed, you only need to enter the command on the terminal:

Rar e myfile.rar

That's it!

In addition, you can find a rar compressed file in your folder,

Right-click and you will find an option "extract to here", which is more convenient! Haha!

12. Display kernel buffer system control information

Dmesg

13 kill

It was okay to use it at the beginning of the installation, but later I found that it would always be stuck when I used it for a while.

Later, we can see that the kernel of ubuntu12.04 is 3.2. Later, we upgraded the kernel to 3.5 and found that this situation would not happen.

View and upgrade the kernel

Uname-

Apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal

After the installation, it is found that when the firefox browser is enabled, sometimes the cpu usage is as high as 100%, and then the cause of 3.2 kernel freezing is found.
