DDE
Deepin Desktop Environment is an elegant, easy to use and reliable domestic desktop environment released by Deepin Technology Co., Ltd. It is primarily written in Golang and Qt5. It was originally written for Deepin Linux, and is ported to Gentoo.
Prerequisites
Add deepin overlay
DDE currently resides in the deepin ebuild repository. There are three primary methods for installing repositories in Gentoo:
Option 1: Install by eselect repository
First emerge app-eselect/eselect-repository and dev-vcs/git:
root #emerge --ask --noreplace app-eselect/eselect-repository dev-vcs/gitThen add the overlay and sync:
root #eselect repository add deepin git https://github.com/zhtengw/deepin-overlay.git
root #emerge --sync deepin
Option 2: Manually add repos.conf
Create a file in the /etc/portage/repos.conf/ directory (create the repos.conf directory first if it does not exist) called deepin.conf. Fill the file's contents with the following code:
/etc/portage/repos.conf/deepin.conf[deepin]
location = /usr/local/overlay/deepin
sync-type = git
sync-uri = https://github.com/zhtengw/deepin-overlay.git
auto-sync = yes
KEYWORDS
For now, only the ~amd64 and ~x86 keywords are supported. So enabling testing global keyword will make it 'quick and easy' for installing DDE.
/etc/portage/make.confACCEPT_KEYWORDS="~amd64"
Profile and USE flags
Read relevant documentation before performing any profile changes.
OpenRC
Using the basic desktop profile:
root #eselect profile set default/linux/amd64/23.0/desktopAdd elogind USE flag in /etc/portage/make.conf, it's also recommended to disable support for other session trackers to avoid conflicts:
/etc/portage/make.confUSE="elogind -systemd"
systemd
Using the systemd profile:
root #eselect profile set default/linux/amd64/23.0/systemdEnsure that X USE flag is included in the system's global USE flags.
Updating system
After setting, ensure everything is up-to-date and remerge @world to make the changes take effect:
root #emerge --sync
root #emerge --deep --with-bdeps=y --changed-use --update --ask --verbose @world
Emerging Deepin Desktop Environment
Set proper USE flags for dde-base/dde-meta, as describe below:
| USE flag | Default | Description |
|---|---|---|
elogind
|
Use sys-auth/elogind to make DDE runs under OpenRC | |
extra
|
Install extra applicaions developed by Deepin | |
grub
|
Install Deepin themes for sys-boot/grub | |
kwin
|
Use the WM based on kwin | |
manual
|
Install dde-extra/deepin-manual User Manual | |
multimedia
|
Install Deepin multimedia suite | |
mutter
|
Use the WM based on mutter | |
plymouth
|
Install Deepin themes for sys-boot/plymouth | |
policykit
|
Yes | Enable PolicyKit authentication support |
screensaver
|
Install Deepin Screensaver module | |
systemd
|
Run with Systemd | |
terminal
|
Yes | Install dde-extra/deepin-terminal Terminal Emulator |
turbo
|
Enable DTK Apps Turbo by dde-extra/deepin-turbo |
For example, to add deepin multimedia suit to the default set of installed applications, do:
root #mkdir -pv /etc/portage/package.use
root #echo "dde-base/dde-meta multimedia" >> /etc/portage/package.use/deepin
The above assumes that /etc/portage/package.use is a directory, which is now the default on the Gentoo minimal install image. If using a single file instead, simply append to /etc/portage/package.use instead of /etc/portage/package.use/deepin in the above.
Then emerge DDE:
root #emerge --ask --verbose --keep-going dde-base/dde-metaConfiguring and running DDE
Assuming that you have setup X11 properly, now going to configure DDE.
Configuring lightdm greeter
There are two greeter we can choose -- lightdm-gtk-greeter and lightdm-deepin-greeter. But lightdm-deepin-greeter cannot run without any normal user, so we use lightdm-gtk-greeter by default.
/etc/lightdm/lightdm.conf[Seat:*]
greeter-session=lightdm-gtk-greeter
Optional: adding a normal user
If there isn't any normal user able to login in to your system, lightdm-deepin-greeter won’t work. Then adding one and setting password. For instance, to create a user called aten who is member of the wheel, users, and audio groups:
root #useradd -m -G users,wheel,audio -s /bin/bash aten
root #passwd aten
Password: (Enter the password for aten) Re-enter password: (Re-enter the password to verify)
Setting default services and running DDE
OpenRC
With display-manager
The configuration file should be modified to use LightDM:
/etc/conf.d/display-managerSet LightDM as the display managerCHECKVT=7
DISPLAYMANAGER="lightdm"
Set dbus, display-manager, NetworkManager, and elogind to come up on boot, and disable dhcpcd if enabled.
root #rc-update add dbus default
root #rc-update add display-manager default
root #rc-update add NetworkManager default
root #rc-update del dhcpcd default
root #rc-update add elogind boot
Start DDE:
root #rc-service dhcpcd stop
root #rc-service NetworkManager start
root #rc-service elogind start
root #rc-service display-manager startWith the deprecated xdm init script
Change the DISPLAYMANGER value in the xdm configuration file to use lightdm.
/etc/conf.d/xdmDISPLAYMANAGER="lightdm"
Set dbus, xdm, NetworkManager, and elogind to come up on boot, and disable dhcpcd if enabled.
root #rc-update add dbus default
root #rc-update add xdm default
root #rc-update add NetworkManager default
root #rc-update del dhcpcd default
root #rc-update add elogind boot
Start DDE:
root #rc-service dhcpcd stop
root #rc-service NetworkManager start
root #rc-service elogind start
root #rc-service xdm startsystemd
Enable NetworkManager and lightdm to be started at boot time:
root #systemctl enable NetworkManager
root #systemctl enable lightdm
Start and login:
root #systemctl start NetworkManager
root #systemctl start lightdm
Removal
To remove DDE, begin by deselecting it:
root #emerge --deselect dde-base/dde-metaThen, clean the package and its dependencies:
root #emerge --ask --depcleanFinally, remove all of the project overlays. For example, if using eselect repository:
root #eselect repository remove deepinTroubleshooting
If you discover any issues, or if you want to contribute, just create a new issue on the deepin ebuild repository Github project or contact the maintainer.
