Set up VNC login without console login in Ubuntu Gnome environment

 It is said that GNOME does not support VNC connection without logging in by default.

So you have to do the following annoying task.


1) gnome-remote-desktop settings

Open "Settings" in gnome-remote-desktop, select "Sharing",

Find "Remote Desktop" or "Screen Sharing" and disable it. 


2) Install x11vnc

sudo apt update

sudo apt install x11vnc


3) Set x11vnc password

x11vnc -storepasswd


4) Set auto-start at boot (create x11vnc.service file)

sudo nano /etc/systemd/system/x11vnc.service


Contents

[Unit]

Description=Start x11vnc at startup

After=display-manager.service


[Service]

Type=oneshot

User=<username>

Group=<groupname>

ExecStart=/usr/bin/x11vnc -forever -usepw -display :0

RemainAfterExit=yes

Restart=on-failure


[Install]

WantedBy=multi-user.target


5) Apply

sudo systemctl daemon-reload

sudo systemctl enable x11vnc.service

sudo systemctl start x11vnc.service
