x11vnc xopendisplay失败_语言综合

概述x11vnc xopendisplay失败

我安装了x11vnc，然后执行x11vnc，但是失败了

以下是错误消息

$x11vnc -display :0 08/05/2017 19:18:22 x11vnc version: 0.9.13 lastmod: 2011-08-10 pID: 7572 08/05/2017 19:18:22 XOpendisplay(":0") Failed. 08/05/2017 19:18:22 Trying again with XAUTHLOCALHOSTname=localhost ... 08/05/2017 19:18:22 *************************************** 08/05/2017 19:18:22 *** XOpendisplay Failed (:0) *** x11vnc was unable to open the X disPLAY: ":0",it cannot continue. *** There may be "Xlib:" error messages above with details about the failure.

我怎样才能解决这个错误？

|| 我不知道以下是否有帮助，但我希望如此

我正在使用远程服务器（Ubuntu 16.04）

使用非root用户帐户安装Git

您尚未提供X11服务器来处理图形窗口。下面按照完整的说明来安装你想要的任何配置的vnc / remote desktop，并从任何 *** 作系统连接到它。

远程桌面之间的任何 *** 作系统的分步指南

我。 windows到/从windows：

使用windows远程桌面软件

二。 linux / Unix从/到任何地方

首先在您要通过远程桌面连接的服务器计算机上执行以下 *** 作：

- Allow other users to vIEw your desktop - Best to require a password - service ssh status - To allow computers to connect with X11 graphics system capabilitIEs as well,you need to install an X11 server on the computer that is trying to connect (clIEnt). So * for a windows computer use XMing * for a linux Ubuntu computer use XQuartz

IIa 。从终端windows到linux的图形支持

- Launch XMing on windows clIEnt - Launch Putty * Fill in basic options * Connection -> SSH -> X11 -> Enable X11 forwarding -> X display location = :0.0 -> MIT-Magic-cookie-1 -> X authority file for local display = point to the Xming.exe executable

IIb 。（b为更好）windows到linux完全的GUI支持。这是你们大多数人想要的。

- install xrdp which uses the remote desktop protocol to present a GUI to the user. It can provIDe a fully functional linux terminal server,capable of accepting connections from rdesktop,freerdp,and Microsoft's own terminal server / remote desktop clIEnts. xrdp is the daemon that handles RDP remote desktop access from windows machines to linux - edit the "/etc/xrdp/xrdp.ini" file to include the line: address=0.0.0.0 right under #background=626x72 line. 0.0.0.0 is the local server address of xrdp - Restart xrdp service - allow xrdp port (probably 3389) through firewall - We also need a VNC server. Install tightvncserver on linux server machine. - run tightvncserver (no need to create a vIEw-only password) - "netstat -lvp | grep vnc" to check out the ports that tightvnc is Listening on for connections - allow the vncserver port from the firewall: sudo ufw allow # - allow the xrdp server - Install xfce4 desktop environment an update to xfce,minimaListic faster and lightweight sudo apt-get install xfce4 - sudo apt-get install xfce4-terminal : way better than xterm - sudo apt-get install gnome-icon-theme-full tango-icon-theme : installs icon sets - Now we modify 2 files to make sure xrdp uses xfce4 * echo xfce4-session >~/.xsession * secondly we modify startup file for xRDP located at /etc/xrdp/startwm.sh so it will start xfce4. Replace the last line with startxfce4 (before it had something which started with a .,but no matter whatever it is,just replace the last line) * restart xrdp service: sudo service xrdp restart - Now you are ready to log into the computer from clIEnt using Remote Desktop (mstsc.exe). Just supply the ipv4 or hostname of the VNC server.

三。 * nix到/从* nix

- ssh -X [preferedUsername]@[targetIpv4Address] : -X flag enales X11 forwarding - accept security certificates from trusted hosts when prompted

四。确保连接安全（可选步骤 – 适用于任何配置）

VNC＆xrdp协议不安全，这意味着它们没有被加密。

要使连接安全，请编辑/etc/xrdp/xrdp.ini文件，使地址变为127.0.0.1。这将是ssh服务器的本地主机地址。 SSH加密将在下面使用隧道的VNC流量。

- sudo service xrdp restart - sudo service ssh restart - pkill Xtightvnc - tightvncserver - putty -> Connection -> SSH -> Tunnels * Source port: 5555 * Destination: localhost:3389

如果以上不起作用：

您可能需要重启两台电脑，

禁用服务器pc上的防火墙（ sudo ufw disable ），然后重新检查（甚至可能需要重新启动）。

如果上述不起作用，那么通过安装冲突的软件包已经搞糟了你的系统。您必须对此进行手动故障排除（如果您正确地按照说明 *** 作，则不太可能达到此步骤）。

祝你好运。
