我需要从另一台 Ubuntu PC 和 Windows PC 远程连接到 Ubuntu PC（需要查看 UI）。我知道我们可以使用 VNC 来做到这一点。任何人都可以向我解释这些步骤或提供包含说明的正确链接。
我遵循了以下步骤： 在需要远程访问的 Ubuntu 机器上安装了 vnc 服务器。我按照以下链接中的说明进行操作
http://www.ubuntu-unleashed.com/2007/10/setup-vnc-server-for-ubuntu-gutsy.html
当我执行第 4 步时：
x11vnc -forever -usepw -httpdir /usr/share/vnc-java/ -httpport 5800
我明白了
