问题[tightvncserver](ubuntu)

硬件A：Ubuntu 20.04 (192.168.1.61)：安装 VNC 服务器并将 OpenVPN 客户端配置添加到一些远程服务器C。

硬件B：MacOS 11.1 (192.168.1.51)：标准预装 VNC 客户端。

当OpenVPN 断开连接时，从B到A我有完美的 VNC 连接。但是当从A（作为客户端）连接到 OpenVPN 服务器时，VNC 连接立即断开。同时，(A <-> B) 和(A <-> B) 工作完美，并且具有与断开连接的 OpenVPN 相同的行为（仅关闭 VNC）。smbpingtraceroute

从B到A（有和没有 VPN）：

% traceroute 192.168.1.61
traceroute to 192.168.1.61 (192.168.1.61), 64 hops max, 52 byte packets
 1  192.168.1.61 (192.168.1.61)  27.855 ms  2.296 ms  35.563 ms

从A到B（有和没有 VPN）：

$ traceroute 192.168.1.51
traceroute to 192.168.1.51 (192.168.1.51), 64 hops max, 52 byte packets
 1  192.168.1.51 (192.168.1.51)  27.855 ms  2.296 ms  35.563 ms

为什么当 OpenVPN 客户端连接到 VNC 服务器时 VNC 不起作用以及如何绕过此行为？我需要将 VNC 服务器连接到 OpenVPN 网络，并且不要同时丢失 VNC 连接。

我不知道为什么，但是当我打开笔记本电脑时，WebGL 可以在 Chromium 和 Firefox 中运行。但是，当我打开 VNC 服务器时，WebGL 将停止工作。它在 VNC 会话和我的屏幕上都不起作用。

我在 Ubuntu 20.04 上使用 LXDE，我知道它不受支持，但我想要一个最小的桌面。哦，我正在运行tightvncserver。

我一直在尝试让任何 vnc 设置为我工作.. 该问题已发布在其他地方.. 但现在特别是一个问题出现了..

我安装并删除了tigervnc，但现在tightvncserver 抱怨它无法启动......我如何创建一个新的xvnc-session？

在 myxvncserver:1.log 里面

我在别处搜索，有人说“哦，只是得到一个新的 xvnc 会话”，因为tigervnc 显然删除了它（感谢tigervnc）

我该如何解决这个问题，所以我可以通过我的 mac 连接到 ubuntu 20.04？

我已经在我的 Ubuntu 18.04 上设置了屏幕共享，并从我的 Mac 远程连接到我的网络。但是，当在我的 Mac 上从屏幕共享输入正确的 vnc://... 时，我收到一条消息，指出远程计算机上的软件与 Mojave 上的此版本的屏幕共享不兼容。但是我在网上读到这很有效。我在使用 TightVNC 时遇到了很多问题，只是无法让它工作，无论我尝试什么，都会出现灰屏

TightVNC 服务器有点问题。

刚刚tightvncserver在 Ubuntu 18.04 上安装了软件包，但它在启动会话时立即崩溃：

/etc/X11/Xvnc-session看起来很标准：

#! /bin/sh

test x"$SHELL" = x"" && SHELL=/bin/bash
test x"$1"     = x"" && set -- default

vncconfig -iconic &
$SHELL -l <<EOF
exec /etc/X11/Xsession "$@"
EOF
vncserver -kill $DISPLAY

我尝试重新安装 TightVNC 服务器，但没有帮助。

什么是 vncconfig？它不应该是 TightVNC 包的一部分吗？如果没有，我在哪里可以找到它？

我已经使用 VNC 很多年了，但我不知道为什么有时会发生这种情况。在一台新的 Ubuntu 16.04 机器上，我首先尝试使用 Vino。它运行良好，但我认为它相当慢，所以我决定将 TightVNC 与 Xfce4 窗口管理器一起使用。然而，我再次得到这个“灰屏”（我之前已经经历过几次......）。
我xstartup的是：

#!/bin/sh

xrdb $HOME/.Xresources
xsetroot -solid grey
startxfce4 &

这里有什么问题？是X server already running on display :1错误吗？怎么样"RANDR" missing on display:1？这么多ignoring unknown encoding信息是什么？

我正在为 Ubuntu 寻找具有最少设置的 vnc 服务器。我用vino、x11vnc、tightvnc、realvnc 尝试了几乎所有你能找到的论坛程序。我只需要一个万无一失的 vnc 设置程序。我想在启动等时运行，但在这一点上我只是想要一些工作。

我能想到的因素太多了，为什么我不能让包括显示管理器、桌面（gnome/unity/etc）在内的东西正常工作[我知道 17.10 使用 gnome，但我还没有验证这一点] ）（我也想保留默认桌面），关于wayland & x11（无 xauthority）等

在戴尔 Optiplex 780 上全新安装和更新 Ubuntu Mate 16.04。

从 Windows 10 客户端连接。

之后直接安装 xRDP 并尝试从 Windows 连接。

进入 RDP 会话并输入凭据。然后...

得到这个错误。

sesman connect ok

运行此命令

:~$ sudo netstat -peant | grep "127.0.0.1"

并得到：

tcp        0      0 127.0.0.1:3350          0.0.0.0:*              LISTEN      0          39396       8082/xrdp-sesman

用grepping“5910”尝试了同样的方法，它什么也没返回。

尝试删除 xrdp，然后先安装tightvncserver，创建vnc 桌面连接，然后安装xRDP，因为这是我之前在其他计算机上设置的方式；

我在其他计算机上使用 VNC，然后发现了 xRDP，然后安装了 xDRP，杀死了 :1 桌面并且能够毫无障碍地使用 xRDP。

在这个桌面上，根据 systemctl 检查的结果，xRDP 服务运行良好。

尝试连接然后查看我的 /var/log/syslog ，结果如下：

从这个帖子中得到了一些想法，

连接错误/问题（Windows 10 RDP 到 XRDP）

其中引用了这个...

https://ubuntuforums.org/showthread.php?t=1314336

但是，没有骰子。

我应该在 Mate 中做一些不同的事情吗？

我应该在另一个线程中发布这个吗？

帮帮我，Ubuntu Mates！

更新！

没有改变任何东西，但重新启动。第一次遇到同样的错误，但后来...

现在我可以从 xRDP 登录提示完全登录，而不会出现以前的错误，但会看到这个灰色的像素化屏幕。

/var/log/syslog 看起来像......
