单独用作关系代词，引导非限制性定语从句，可放在主句之前(常译为：正如)或之后(常译为：这一点)，且主从句之间一般要用逗号隔开。如：
As everything is moved to the cloud, virtualized remote desktop becomes increasingly popular in the industry as a way to enhance employee's productivity.
正如所有一切已经移到云端，在工业界作为一种提高员工效率的方式，虚拟化的远程桌面变得越来越流行。

用作介词，意为“作为”、“当作”、“充当”。如：

What is X2Go?

GPL-ed的讨论
NX闭源的同时NX库被标为曾经使用GPL协议
这里的while你要根据前文说的前后，确定到底是指的是后来还是但是的意思


As everything is moved to the cloud, virtualized remote desktop becomes increasingly popular in the industry as a way to enhance employee's productivity.
正如所有一切已经移到云端，在工业界作为一种提高雇员效率的方式，虚拟化的远程桌面变得越来越流行。
Especially for those who need to roam constantly across multiple locations and devices, remote desktop allows them to stay connected seamlessly to their work environment.
尤其对需要经常漫游，横跨多个位置和设备的这些人，远程桌面允许他们无缝地保持连接到它们的工作环境。
Remote desktop is attractive for employers as well, achieving increased agility and flexibility in work environments, lower IT cost due to hardware consolidation, desktop security hardening, and so on.
远程桌面对雇主来说也是有吸引力的，在工作环境中实现增加（灵敏度）敏捷性与灵活性，由于硬件的整合，桌面的安全强化等方面，实现了更低的IT花费。
In the world of Linux, of course there is no shortage of choices for settings up remote desktop environment, with many protocols (e.g., RDP, RFB, NX) and server/client implementations (e.g., TigerVNC, RealVNC, FreeNX, x2go, X11vnc, TeamViewer) available.
在linux的世界中，当然不缺少启动远程桌面环境的选择，有很多协议(e.g., RDP, RFB, NX)和客服实现(e.g., TigerVNC, RealVNC, FreeNX, x2go, X11vnc, TeamViewer)可用。
Standing out from the pack is X2Go, an open-source (GPLv2) implementation of NX-based remote desktop server and client.
从这些包中脱颖而出的有X2Go--一个开源实现(GPLv2)，基于NX的远程桌面服务器与客户端。
In this tutorial, I am going to demonstrate how to set up remote desktop environment for Linux VPS using X2Go.
在本指南中，我将要展示如何使用X2Go为linux vps建立远程桌面环境。


The history of X2Go goes back to NoMachine's NX technology. The NX remote desktop protocol was designed to deal with low bandwidth and high latency network connections by leveraging aggressive compression and caching.
X2Go的历史可以追溯到NoMachine公司的NX技术。NX远程桌面协议设计用来处理低带宽和高延迟的网络连接。
Later, NX was turned into closed-source while NX libraries were made GPL-ed. This has led to open-source implementation of several NX-based remote desktop solutions, and one of them is X2Go.
后来，当NX库许可证到期时，NX转向了闭源。这导致一些基于NX远程桌面方案的开源实现，其中之一就是X2Go。
What benefits does X2Go bring to the table, compared to other solutions such as VNC? X2Go inherits all the advanced features of NX technology, so naturally it works well over slow network connections.
和其它方案例如VNC相比，X2Go都有哪些可以摆到桌面上的收益呢？X2Go继承了所有NX技术的高级特性，因此很自然地在慢速网络连接之上工作的很好。
Besides, X2Go boasts of an excellent track record of ensuring security with its built-in SSH-based encryption.
除此之外，X2Go自夸是一个完美的记录跟踪，用它内置基于SSH的加密确保安全。
No longer need to set up an SSH tunnel manually. X2Go comes with audio support out of box, which means that music playback at the remote desktop is delivered (via PulseAudio) over network, and fed into local speakers.
不再需要手动建立一个SSH隧道。X2Go伴随着开箱即用的声音支持，它意味着在远程桌面的音乐回放通过网络被转发（经由脉冲音频），并注入本地扬声器。
On usability front, an application that you run on remote desktop can be seamlessly rendered as a separate window on your local desktop, giving you an illusion that the application is actually running on the local desktop.
在可用性方面，你在远程桌面中运行的应用程序，能被无缝地在本地桌面上渲染为一个独立的窗口，给你一个应用程序就是运行在本地桌面的假象。
As you can see, these are some of its powerful features lacking in VNC based solutions.
正如你所看到的，这些是它强大特性中的一些，正是基于VNC方案所缺少的。


X2GO's Desktop Environment Compatibility

As with other remote desktop servers, there are known compatibility issues for X2Go server. Desktop environments like KDE3/4, Xfce, MATE and LXDE are the most friendly to X2Go server.
正如其它远程桌面服务器一样，X2Go server也有已知的兼容性问题。像KDE3/4,Xfce,MATE和LXDE这样的桌面环境对X2Go server都比较友好。
However, your mileage may vary with other desktop managers. For example, the later versions of GNOME 3, KDE5, Unity are known to be not compatible with X2Go.
然而，你的里程会受到其它桌面管理器的影响。例如，最新版本的GNOME 3, KDE5，Unity与X2Go不兼容。
If the desktop manager of your remote host is compatible with X2Go, you can follow the rest of the tutorial.
假如你远程主机的桌面管理器兼容X2Go，请接着阅读指南的其余部分。


Install X2Go Server on Linux

X2Go consists of remote desktop server and client components. Let's start with X2Go server installation.
X2Go 由远程桌面服务器和客户端组件组成。让我们开始X2Go server安装。
I assume that you already have an X2Go-compatible desktop manager up and running on a remote host, where we will be installing X2Go server.
我假设你已经在远程主机上启动并运行了一个X2Go兼容的桌面管理器，我将在这个机器上安装X2Go服务器。
Note that X2Go server component does not have a separate service that needs to be started upon boot. You just need to make sure that SSH service is up and running.
注意X2Go server组件没有一个在系统引导时而启动的独立服务。你只需要确保ssh服务启动并运行。
