使用 lightdm 和 x11vnc 的 vnc 在有效登录后立即断开连接

从精确的 64 位服务器安装开始，我配置了以下内容；

sudo apt-get install lightdm x11vnc
sudo dpkg-reconfigure lightdm

在 /etc/init/x11vnc.conf 中，我放置了；

start on login-session-start
script
/usr/bin/x11vnc -xkb -auth /var/run/lightdm/root/:0 -noxrecord -noxfixes -noxdamage -forever -bg -rfbport 5900 -o /var/log/x11vnc.log
end script

使用 Windows 中的 UltraVNC，我连接并输入有效的登录信息，窗口立即关闭。vnc 日志显示；

知道我遗漏了什么吗？

答案1

问题其实很简单，我没有安装底层桌面提供程序。另外，我的设备没有视频卡和视频驱动程序，因此没有帧缓冲区可以进行渲染。

对我有用的解决方案是在这个帖子。

答案2

lightdm我最终通过将桌面管理器从 切换到解决了这个问题gdm。

以下是详细说明：如何从 LightDM 切换到 GDM？

答案3

同样的问题也发生在这儿，解决方案是应用这个答案并正确配置颜色深度（我的情况是 32 位）。后者是 remmina 的问题。

答案4

我遇到了同样的问题（基本上是完全相同的日志输出），在我的例子中，这是因为我的主文件夹中的一个文件.ICEauthority不知何故被 root 所拥有。可能是因为我在调试期间使用 sudo 运行了某些操作。将用户切换回我的用户解决了这个问题。

一些有用的日志记录可能在/var/log/lightdm/
