DDE is a powerful desktop environment developed by UnionTech. It contains dozens of self-developed desktop applications.
Download the openEuler ISO file and install the OS.
Update the software source.
sudo dnf update
sudo dnf install dde
Set the system to start with the graphical interface.
sudo systemctl set-default graphical.target
Reboot the system.
After the reboot is complete, use the user created during the installation process or the openeuler user to log in to the desktop.
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.
