在ubuntu18.04中vnc自启动时报错“vncserver: The HOME environment variable is not set“如何处理？

答: 在/lib/systemd/system/vnc.service指定以某用户登陆即可,
模版如下:

$ cat /lib/systemd/system/vnc.service
[Unit]
Description=Vnc Server

[Service]
ExecStart=/sbin/runuser -l yourusername -c "/usr/bin/vncserver"

[Install]
WantedBy=multi-user.target
