Title: How to optimize and customize the system on Kirin operating system?

Kirin operating system is an open source operating system based on the Linux kernel, which is open, stable and secure. In order to better use and customize the Kirin operating system, we can perform system optimization and customization. This article will introduce some system optimization techniques and customization methods of Kirin operating system, and provide code examples for readers' reference.

1. System optimization

1. Upgrade software package

Kirin operating system is an open source project that is continuously updated and improved. In order to maintain system stability and security, we should regularly upgrade software packages. You can use the following command to upgrade the software package:

sudo apt update  # 更新软件包源列表
sudo apt upgrade  # 更新已安装的软件包
sudo apt autoremove  # 移除无用的软件包和依赖

2. Disable unnecessary services

In order to improve the performance and security of the system, we can disable some unnecessary services. You can use the following command to view the currently running services:

sudo systemctl list-units --type=service

You can use the following command to disable unnecessary services:

sudo systemctl disable <service_name>  # 禁用指定的服务

3. Optimize the kernel parameters

By adjusting the kernel parameters , we can optimize the performance and stability of the system. You can edit the /etc/sysctl.conf file and add or modify the corresponding parameters. For example, you can add the following parameters to the file to optimize network performance:

net.core.rmem_default = 256960
net.core.rmem_max = 256960
net.core.wmem_default = 256960
net.core.wmem_max = 256960

Then use the following command to make the parameters effective:

sudo sysctl -p

2. System customization

1. Replacement Desktop environment

Kirin operating system uses the GNOME desktop environment by default, but we can change other desktop environments according to personal preferences. You can use the following command to install other desktop environments, taking KDE as an example:

sudo apt install kubuntu-desktop  # 安装KDE桌面环境

After the installation is complete, log out of the current user and select the newly installed desktop environment to log in.

2. Customize startup items

We can customize startup items to run specific commands or applications when the system starts. You can edit the .desktop file in the ~/.config/autostart directory to create custom startup items. Example:

[Desktop Entry]
Type=Application
Exec=<command_or_application>  # 自定义命令或应用程序
Hidden=false
NoDisplay=false
X-GNOME-Autostart-enabled=true
Name=<name_of_custom_entry>  # 自定义启动项名称

After saving the file, the custom startup item will run automatically when the system starts.

3. Modify the theme and icons

In order to make the system more personalized, we can modify the theme and icons. New themes and icons can be installed using the following command:

sudo apt install <theme_package_name>  # 安装主题
sudo apt install <icon_package_name>  # 安装图标

Then select the new theme and icons in the system settings.

Summary:

Through system optimization and customization, we can better use and personalize the Kirin operating system. In this article, we introduce some system optimization tips, such as upgrading software packages, disabling unnecessary services and optimizing kernel parameters. At the same time, we also introduced methods of system customization, such as changing the desktop environment, customizing startup items, and modifying themes and icons. I hope this article will help readers use and customize the Kirin operating system.
