我正在尝试使用 TightVNC 在我的 Lubuntu 20.04 / LXQt / LightDM / Xorg / openbox 机器上设置 vnc 服务器。
先描述一下我的问题：当我使用 TightVNC（java 版本）从 Windows 机器连接时，我可以连接，我可以看到我的 python 应用程序运行正常，这是我在 Lubuntu 机器上本地启动的，但我看不到任何桌面。全是灰色的。我的 ~/.vnc/nb-lubuntu:1.log 显示了很多错误。
这是我的~/.vnc/xstartup：
#!/bin/sh
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc &
exec startx &
/usr/bin/openbox &
/usr/bin/startlxqt
这是我的 .vnc 下的 :1.log，其中充满了错误：

最后一行反映了我目前的心理状况。显然 lxqt 没有启动。我的桌面是“X”作为后备？我做错了什么？谢谢您的帮助！
答案1
我终于找到了一个替代方案：
x2go。
在 lubuntu 下安装它很容易
- sudo apt-get 安装软件属性-通用
- sudo 添加 apt 存储库 ppa:x2go/stable
- sudo apt-get 更新 sudo apt-get 安装 x2goserver x2goserver-xsession
然后在 Windows 下安装 x2go 客户端并配置会话。非常直观，桌面清晰可见（现有桌面的副本，没有单独的会话）。
