DDE Installation

Introduction

DDE is a powerful desktop environment developed by UnionTech. It contains dozens of self-developed desktop applications.

Procedure

Download the openEuler ISO file and install the OS.
Update the software source.
```
sudo dnf update
```
Install DDE.
```
sudo dnf install dde
```
Set the system to start with the graphical interface.
```
sudo systemctl set-default graphical.target
```
Reboot the system.
```
sudo reboot
```
After the reboot is complete, use the user created during the installation process or the openeuler user to log in to the desktop.
Notes:
DDE does not allow login as the root user. DDE has a built-in openeuler user whose password is openeuler.

Now you can use DDE.
