Вот моя VNC часть конфигурации LightDM.
[VNCServer]
enabled=true
command=Xvnc -rfbauth /etc/vncpasswd
port=5900
width=800
height=600
depth=24
Я использую Xfce 4.
Во всяком случае, проблема заключается в том, чтобы войти. Я обнаружил, что когда я вошел на свой физический, VNC не может войти. И наоборот, когда я не вошел на свой физический, VNC работает отлично, тогда как физический не смог войти.
Изменение среды рабочего стола на GNOME приводит к тому же.
Вот мой журнал LightDM.

Предыдущие 4 секунды указывают на то, что я захожу на физическую. После показывает этап входа в VNC. Я думаю
[+36.82s] WARNING: Error activating login1 session: GDBus.Error:org.freedesktop.DBus.Error.NotSupported: Operation not supported
действительно имеет значение.
Я искал информацию о сообщении об ошибке, но оно не сработало. Так что я хотел бы спросить, как это решить?
