HOWTO : Install Deepin Desktop Environment on Ubuntu Desktop 18.04 LTS

Deepin Desktop Environment (DDE) is an open source project by Deepin Technology Ltd. Co., Wuhan, China. Besides install Deepin Linux 15.5 or higher, you can install it on Ubuntu Desktop 18.04 LTS.

Install Deepin Desktop Environment (DDE)

sudo add-apt-repository ppa:leaeasy/dde
sudo apt-get update
sudo apt install dde

The following is for experiment only (not recommended by the PPA creator).

sudo apt install dde deepin-gtk-theme dde-control-center-plugin-notify dde-control-center-plugin-weather redshift libfprint0 dnsmasq cgroup-tools imwheel libpam-fprintd fprintd network-manager-l2tp network-manager-openconnect network-manager-openvpn network-manager-vpnc minicom deepin-calculator dde-file-manager

Install RecordMyDesktop (Optional)

sudo apt install gtk-recordmydesktop

* when "Window Effect" is disabled, "Deepin Screen Recorder" and "Multitasking View" will be disabled too.

Set Font of the system (Optional)

Set Font to "Ubuntu" and "Ubuntu Mono" and set font size larger when necessary.

Disable Window Effect Mode (Optional)

When you find booting to desktop taking a longer time and playing video files lagging, you need to consider to disable the Window effect as your display card is not strong enough.


The following optional settings are for Chinese only. Ubuntu default ibus is not compatible with Deepin DDE and you need to use fcitx instead.:

If you are using English version Ubuntu, you are required to install the Traditional Chinese fonts or Simplified Chinese fonts.

Traditional Chinese

sudo apt install language-pack-gnome-zh-hant-base language-pack-gnome-zh-hant

or

Simplified Chinese

sudo apt install language-pack-gnome-zh-hans-base language-pack-gnome-zh-hans

Install Cangjie Quick Input Method (Optional)

sudo apt install fcitx fcitx-table-quick-classic fcitx-config-gtk

Install Cantonese Input Method (Optional)

sudo apt install fcitx fcitx-table-cantonese fcitx-config-gtk

Install Cangjie 3rd Generation Input Method (Optional)

sudo apt install fcitx fcitx-table-cangjie3 fcitx-config-gtk

Install Cangjie 5th Generation Input Method (Optional)

sudo apt install fcitx fcitx-table-cangjie5 fcitx-config-gtk

After installing desired Chinese Input Method, go to "Language Support" to set from "ibus" to "fcitx" and make sure to install missing packages when asked in launching "Language Support". To toggle the Input Method by pressing "Ctrl+Space" and set your Input Method as default when necessary.





You can even switch between Gnome and Deepin desktop environment when you are going to login. If you want to delete the Deepin DDE forever, you can run the following commands :

sudo apt remove dde

or

sudo apt remove dde dde* deepin* deepin-gtk-theme dde-control-center-plugin-notify dde-control-center-plugin-weather redshift libfprint0 dnsmasq cgroup-tools imwheel libpam-fprintd fprintd network-manager-l2tp network-manager-openconnect network-manager-openvpn network-manager-vpnc minicom deepin-calculator dde-file-manager
sudo apt autoremove
sudo apt update

Deepin Linux 15.5

中國武漢深度科技公司的深度作業系統 15.5 (Deepin Desktop) 是基建於 Debian Linux 的桌面系統。深度系統實現了 Linux 的高度客制化的技術，它媲美蘋果電腦 macOS 作業系統。

深度系統 15.5 安裝容易和直接，沒有太多的輸入和選項。當安裝在 Virtualbox 虚擬機器時，它會提供特效模式 (Effect mode) 或普通模式 (Common mode) 選擇。普通模式運作行得比較快，但沒有了特別效果。

在使用深度系統 15.5 時極有使用蘋果電腦 macOS 的感覺。使用介面非常直觀和華麗，你並不會迷失於大量的選項當中。

它的軟件庫 (Deepin Store) 收集了很多實用的軟件，並且安裝和移除都非常容易。它的軟件庫極有蘋果電腦 macOS 的 Apps Store 味道。可以看得出武漢深度科技公司曾經投入大量資源來開發這系統。

這個作業系統極之適合 Linux 初學者或一些要求簡潔和直接的用家。這也是 Ubuntu Linux 以外的另一個不錯的選擇。但是美中不足之處是它沒有全碟加密和密碼只接受最多十六位字元，而且有些軟件的版本比較老舊。




Wuhan Deepin Technology Co. Ltd. (China) develops a Debian based Linux system namely Deepin Desktop. The current version as at this writing is 15.5. The outlooks of Deepin is much like Apple macOS.

Installation of Deepin 15.5 is very easy and simple. A few information is required to fill in or select in the installation. When installed in Virtualbox, you have a chance to select "Effect mode" or "Common mode". Common mode is the fastest mode comparing with Effect mode. Deepin Desktop 15.5 is very easy to use. The design is very straight forward and simple. If you have experience in Apple macOS, you will feel that it is very similar.

There are some useful software in Deepin Store and it much like Apps Store in macOS. The installation and uninstallation of any software is very easy. It is believed that Wuhan Deepin Technology has invested a lot of resources of building this Linux distribution.

Deepin Desktop is suitable for newbies of Linux and someone who loves simple operation. If you do not like Ubuntu Linux, you may try Deepin Desktop instead. The only downsides of Deepin are no full disk encryption, the maximum length of user password limited to 16 characters and some software are a little bit out-dated.

That's all! See you.

Linux 的我見

每一個人選擇使用 Linux 的原因和理由各有不同，但大部份人都是原先是使用視窗 (Windows) 的。他們大多都有一個共同點，就是經常抱怨找不到和視窗一樣的應用軟體的代替品。但這個問題鮮有在蘋果 (Apple macOS) 的使用者中發生。問題是出在那裡呢？

視窗、蘋果及 Linux 在基本上是不同的產品，它們都有着自己的特性。蘋果是源於 BSD 系統，它是 Unix 系統；Linux 是類 Unix 系統及自行開發；而視窗是一個自行開發的非 Unix 系統。它們都有着的不同發展方向，除了 Linux，視窗和蘋果都很早在桌面 (Desktop) 方面上應用。

視窗專門經營軟體業務，而蘋果則為主要經營硬件業務，而 Linux 基本上是非牟利的。

蘋果也沒有很多與其他商業化產品一樣的代替品，但蘋果用戶並沒有如其他的視窗使用者使用 Linux 時的要求和抱怨。我想是因為蘋果用戶是一個獨特的使用群組，他們沒有抱怨沒有相似的代替品，但他們接受使用與視窗用戶所使用的不一樣和與別不同的產品。

基於 Linux 是開源及基本上是免費的，大多數的開發人員都是利用自己的私人時間來開發軟體，所以其開發出來的軟體大多數沒有在商業化上作出考慮；多數的開發人員都是開發給自己或一小撮人使用。其後他們有的也開發了一些與其他商業化產品的類似物，但並非是其代替品，也有一些應用是其他商業化產品沒有的。Linux 的獨特性可見一班。

其實視窗的使用者在使用 Linux 時不應有與使用視窗的要求。應當接受各個不同類型的作業系統的不同特性和發展。視窗的使用者與蘋果的用戶在性格上和要求上大有不同，在此，我非常欣賞蘋果用戶的可塑性。所以視窗的使用者對 Linux 會不會過於「又要馬兒好，又要馬兒不吃草」呢？

開源的 Linux 造就各式各樣的版本，各個版本都有其獨特的性格。各個版本的基本操作指令和架構是大致相同，最大的分別在於軟件包管理指令和桌面系統 (Window Manager)。不同版本的 Linux 有不同版本的軟件包管理和桌面系統。

Linux 吸引之處在於可塑性非常高，客制性的能力可以出神入化。再加上所有編程語言和編譯器是完全開源和免費的。這做就了多樣化的工具軟件供給多樣化的應用。每個軟件工程師都可建做自己具有個人特色的 Linux 版本或應用系統。

至於為何沒有與其他作業系統的應用軟體一模一樣的產品，我想這與知識產權不無關係的，這就不能怪責 Linux 的不體貼了。俗語有話「若要人似我，除非兩個我」。

Will Linux Be Infected By Malware Or Not?

When I came to know Linux, almost all advanced Linux users told me that Linux is impossible to be infected by virus and malware due to its excellent design. Except root or sudoer, nobody has the privilege to do harm on the system including malware. In case your Linux is infected, only you (the user) is affected. Therefore, you are not required to install any anti-virus or anti-malware application on Linux system. Meanwhile, Linux will not infected Windows based malware. Moreover, Linux developers tried to harden the Linux kernel in many ways, such as ASLR, XD/NX, SELinux, Apparmor, and Gentoo's harden-kernel, etc.

After being an Information Security Enthusiast, I recognized that it is totally not true. In my opinion, Linux just like any other operating systems that can be infected by malware and the interference is not limited to your system only. There are many such news recently.

Linux users can be infected with malware in many ways and some malware are cross-platform software too. The most common way to be infected malware is by surfing internet with your browsers. The other most common way is not keeping your Linux system up-to-date. For example, the very famous Heartbleed vulnerability is still vulnerable for over 200,000 devices in the world after more than a year.

Once you are infected, the malware can perform privilege escalation on your Linux system to gain the rights of root. How this to be done? The most common one is vulnerability of the kernel and/or application software. The other is by social engineering. The most insecure part is human being anyway.

Furthermore, most modern Linux distributions implied sudoer. Sudoer has the rights of root. However, most sysadmins or users will set their account name and password in a very weak way. In addition, the password of root can be easily guessed in most cases for those distributions that not using sudoer. I just name some of them here and there are many ways to get root privilege on Linux systems, for example, misconfiguration of Linux system and/or application software.

Hereby, I name some software, skills and tools as well as technologies on Linux malware for your reference. Hope you all understand that Linux is not a bullet-proof system. It is very easy to break for sure. Finally, I would like to introduce how I hardening Ubuntu for my current daily use, here you are.
