I. Install the font

The Chinese font in Ubuntu 12.04 is neat, and I 've been reading it for a long time. It's not good for my eyes. I used to get used to the font in Windows. This time, we continue to use the font,

1. First, download the font file: http://www.linuxidc.com/Linux/2009-11/22691.htm (msyh. ttf and msyhbd. ttf ).

2. Run the following command: sudomkdir/usr/share/fonts/truetype/msyahei. Create the msyahei directory and copy the downloaded font to the directory.

3. Execute the command: sudochmod 664 msyh * to change the font permission.

4. Refresh the font cache, execute the command: sudo fc-cahce, and then restart it.

Ii. Solve the Problem of computer fever and fan conversion in Ubuntu (for N cards)

Here, there is a solution on the Internet, which is listed here (original address: http://www.linuxidc.com/Linux/2014-04/100087.htm)

Write the following two commands to/etc/rc. local. Before exit0, disable the dedicated display every time the system is started.

Echo IGD>/sys/kernel/debug/vgaswitcheroo/switch

Echo OFF>/sys/kernel/debug/vgaswitcheroo/switch

However, I don't know why. after these two commands are written in local, every time the computer enters the login interface, after entering a few passwords, the computer will be stuck. Sometimes the password will be stuck before it is entered, and there will be no way to enter the system, after deleting the above two commands, you can log on normally. Some people say this method is acceptable on the Internet, but my computer (Lenovo y460) cannot work. It may be that my computer hardware does not match. So I found another article. After using this article, the notebook fan was greatly reduced and there was no fever. Address: http://www.linuxidc.com/Linux/2014-04/100086.htm

Below, I will list the main commands:

Sudoadd-apt-repository ppa: bumblebee/stable

Sudoapt-get update

Sudoapt-get install bumblebee-nvidia

Sudoreboot

After running the command, enter

Lspci | grep VGA

The following lists the operations of Intel and NVIDIA dual display. The NVIDIA graphics card information is followed by an "revff", indicating that the dual display has been disabled. So far, the laptop heat dissipation problem has been solved perfectly.

3. Adjust and save screen brightness

After I just installed ubuntu, every time I restart my computer and log on to the system, the screen brightness is the biggest, which is very dazzling. Every time I restart my computer, I have to manually adjust the brightness, which is very troublesome.

The following method can adjust the brightness of the screen after each computer restart and adjust it to the appropriate brightness.

First, cd/sys/class/backlight/, and then ls to check which folders are in this directory. on my computer, there are three folders:

Acpi_video0 acpi_video1 intel_backlight, where the computer may be different. Every folder contains brightness. This is a file to adjust the screen brightness. We use

Sudocat/sys/class/backlight/acpi_video0/brightness, you can see the screen brightness after each computer restart.

The next step is to set the brightness of these files until a proper brightness is reached.

Run the following command:

Echo3>/sys/class/backlight/acpi_video0/brightness

Echo3>/sys/class/backlight/acpi_video1/brightness

I changed the brightness under acpi_video0 and acpi_video1, and solved the screen brightness problem.
