Deepin desktop version of the Manjaro community is no longer maintained, want to use deepin desktop also need to install their own, the installation process encountered more problems, recorded.

Deepin desktop version of the Manjaro

Step 1: Install Manjaro

I downloaded the Plasma Desktop version of Manjaro, which is the KDE version, and other versions should be similar. Update your system after the installation is complete.

Step 2: Install xorg

Xorg is an open source implementation of the X Window System, on which most current window managers or desktop systems are based. deepin needs to use it.

1

sudo pacman -S xorg xorg-server

Step 3: Install Deepin Desktop Environment

1

sudo pacman -S deepin

Step 4: Install additional Deepin software (optional)

1

sudo pacman -S deepin-extra

Note that selecting Install All results in the following error.

After analysis, it was found that there is a conflict in the deepin-extra group dde device-formatter, and the solution is relatively simple, that is, do not install dde device-formatter.

Step 5: Configure lightdm display manager

Common display managers.

  • Entrance - EFL-based display manager, highly experimental in nature.
  • GDM - GNOME display manager.
  • KDM - KDE4 display manager (no longer in further development).
  • LightDM - Cross-desktop display manager, can use various front-ends written by any toolset. (ubuntu defaults to this)
  • LXDM - LXDE display manager, can be used independently of the LXDE desktop environment.
  • MDM - MDM display manager, used in Linux Mint, a fork of GDM 2.
  • SDDM - QML-based display manager, successor to kdm for KDE 4; recommended for Plasma 5 and LXQt.
  • SLiM - Lightweight and elegant graphical login solution (no longer in development).
  • XDM - X display manager with XDMCP, host selection support.

Deppin uses lightdm, so installation and configuration is required:

1
2

sudo pacman -S lightdm
sudo nano /etc/lightdm/lightdm.conf

Find the following line.

1

# greeter-session = Session to load for greeter

Remove the comment and modify it as follows.

1

greeter-session = lightdm-deepin-greeter

After saving and starting the service, you can find that the service does not start properly:

Installing the service, the following error is reported.

sudo systemctl enable lightdm.service
Failed to enable unit: File /etc/systemd/system/display-manager.service already exists and is a symlink to /usr/lib/systemd/system/sddm.service.

That is, currently in the desktop environment is using sddm, so can not run at the same time, the solution is also relatively simple, CTRL + ALT + F2 into the command line environment. Execute the following command.

1
2
3
4

sudo systemctl disable sddm.service
sudo systemctl stop sddm.service
sudo systemctl enable lightdm.service
sudo systemctl start lightdm.service

Once done, reboot and you will be on the deepin desktop.

Step 6: Configure the deepin-kwin window manager

Install screenfetch and check which window manager is currently in use.

You can see that the current use is Deepin WM, deepin-wm is dde old window manager, upstream is gnome mutter. but mutter is heavier than kwin, so now deepin-kwin is upstream is kwin, kwin is relatively light and fast a little, still in the perfect stage, the initial use will be more laggy.

Deepin WM can also be used, but there will be problems such as desktop wallpaper can not be replaced, so it is still recommended to install deepin-kwin.
