The Deepin Desktop Environment (DDE) is the desktop environment of the Chinese Deepin Linux distribution.

Installation

To get a minimal desktop interface, you may start by installing deepin group. This will pull all the basic components.

The deepin-extra groups contains some extra applications for a more complete desktop environment.

To be able to use the integrated network administration, the networkmanager package is required, and the NetworkManager.service must be started and enabled.

Launching Deepin Desktop Environment

Via a Display Manager

To use the default DDE's lightdm greeter you have to modify the configuration file under the [Seat:*] section, to state:.

/etc/lightdm/lightdm.conf

[Seat:*]
...
greeter-session=lightdm-deepin-greeter

Note that a valid home directory must exist for a user other than root for the greeter to work.

Via xinit

To use Deepin via xinit, you'll need to add the following to your .xinitrc file.

~/.xinitrc

exec startdde

Troubleshooting

No background after resuming from standby

Because of the way the NVIDIA driver stores its FBOs [1], it happens that after resuming from standby the background suddenly disappears, leaving only a white screen with possibly some color noise on it. The bug appears to be fixed in GNOME upstream, but the Deepin desktop environment still has it.

A possible workaround would be restarting the window manager every time the computer resumes from suspension. A way to do that would be creating the following systemd service

/etc/systemd/system/resume@.service

[Unit]
Description=User resume actions
After=suspend.target

[Service]
User=%I
Type=simple
ExecStart=/usr/bin/deepin-wm-restart.sh

[Install]
WantedBy=suspend.target

That executes the following script

/usr/bin/deepin-wm-restart.sh

#!/bin/bash
export DISPLAY=:0
deepin-wm --replace

Once those two files are created in the correct directories, in order to enable the script it's sufficient to run these commands:

# chmod +x /usr/bin/deepin-wm-restart.sh
# systemctl enable resume@user
# systemctl start resume@user 

The first command makes the script you created executable, the second makes sure that the service always start at boot and the last one starts the service immediately so you can test the workaround without having to reboot the system.

Bug Reporting

Any upstream or arch packaging related bugs should be reported here. All deepin developers will see the bug reports and solve them as soon as possible.
