Failed to execute child process “dbus-launch“

在ubuntu中搭建vnc桌面环境，安装 Minimal Xfce Desktop

#精简安装
sudo apt-get install --no-install-recommends xubuntu-desktop 

遇到如下报错。

Unable to contact settings server
Failed to execute child process “dbus-lauch”(xxxxx)

此问题的解决方案是安装’dbus-x11’。

sudo apt-get install dbus-x11

安装以后，重启vncserver服务，问题成功得到解决了。
