在Google Cloud（Debian）Compute Engine上启动X服务器 [英] Start X server on Google Cloud (Debian) Compute Engine

问题描述

我已经在Google云上设置了Debian（jessie）VM。我已经安装了具有所需依赖项的Xfce。现在，我尝试使用命令'startx'启动X显示服务器，但出现以下错误

I have set up a Debian(jessie) VM on Google cloud. I have installed Xfce with needed dependencies. Now I am trying to start the X display server with command 'startx' But I get following error

--------
Using system config directory "/usr/share/X11/xorg.conf.d"
(EE) 
Fatal server error:
(EE) no screens found(EE)

Following messages are present in /var/log/Xorg.0.log

有Internet上提出了一些解决方案，其中大多数建议更改sshd配置。我的sshd_config文件现在具有以下条目（以及其他条目）

There are a few solutions proposed on the internet and most of them suggest sshd config changes. My sshd_config file now has following entries(amongst others)

-----------
X11Forwarding yes
X11UseLocalhost no
X11DisplayOffset 10
AddressFamily inet
-----------

在我的本地计算机上X11Forwarding也设置为yes。

X11Forwarding is set to yes on my local machine as well.

是否存在已知的限制/设置造成这种情况的Google云？

Is there is a known limitation/setting of Google cloud that is causing this?

感谢您的帮助和建议！

推荐答案

如果您对使用远程运行的XFCE不感兴趣，并且只希望使用X服务器进行测试自动化，请使用Xvfb代替x.org。不需要安装视频硬件。

If you're not interested in using the remotely running XFCE and you only want an X server for test automation, use Xvfb instead x.org. It does not require video hardware to be installed.

在远程主机上：

xvfb :1 &
export DISPLAY=:1
startxfce4 &
