$ vncserver -kill :1
Change the file xstartup with a text editor
$ vi ~/.vnc/xstartup
The content of file xstartup:
#!/bin/sh

# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

Now, restart the VNC server.
$ vncserver
3. Setup the VNC server as a systemd service
Create a new file in the directory /etc/systemd/system/
$ sudo vim /etc/systemd/system/vncserver@:1.service
The content of file vncserver@:1.service:
[Unit]
Description=Start TightVNC server at startup
After=syslog.target network.target
[Service]
Type=forking
User=$USER
PAMName=login
PIDFile=/home/$USER/.vnc/%H%i.pid
#ExecStartPre=/usr/bin/vncserver -kill %i > /dev/null 2>&1
ExecStart=/usr/bin/vncserver -depth 24 -geometry 1920x1200 %i
ExecStop=/usr/bin/vncserver -kill %i
[Install]
WantedBy=multi-user.target
Then,
$ sudo systemctl daemon-reload
Enable the service file.
$ sudo systemctl enable vncserver@\:1.service
Kill the instance is running
$ vncserver -kill :1
Start the systemd service.
$ sudo systemctl start vncserver@\:1.service
If the service runs correctly,
$ sudo systemctl status vncserver@\:1.service
