VNC URLs look like this: -
vnc://192.168.1.19:5901
Alternatively, one can start the same VNC Viewer client from the command-line, via Terminal, and this command: -
open vnc://ubuntu:5901
For the record, I installed TigerVNC on my Ubuntu box: -
dpkg --list | grep tiger
ii tigervnc-common 1.7.0+dfsg-8ubuntu2 amd64 Virtual network computing; Common software needed by servers
ii tigervnc-standalone-server 1.7.0+dfsg-8ubuntu2 amd64 Standalone virtual network computing server
with this xstartup : -
cat ~/.vnc/xstartup
#!/bin/sh
export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
gnome-session &
nautilus &
with the VNC Server's password encoded in: -
-rw------- 1 dave dave 8 Apr 10 15:19 /home/dave/.vnc/passwd
The thing that I initially missed, but then discovered, was that, by default, TigerVNC automatically starts assuming that all client connections will be local i.e. only from the box running the VNC Server itself !!!
This is easily mitigated when one starts the VNC Server: -
vncserver --localhost no
New 'ubuntu18:1 (dave)' desktop at :1 on machine ubuntu18
Starting applications specified in /home/dave/.vnc/xstartup
Log file is /home/dave/.vnc/ubuntu18:1.log
Use xtigervncviewer -SecurityTypes VncAuth,TLSVnc -passwd /home/dave/.vnc/passwd ubuntu18:1 to connect to the VNC server.
with the .PID file: -
cat ~/.vnc/ubuntu18\:1.pid
7589
and the log file: -
cat ~/.vnc/ubuntu18\:1.log

For reference, this was a useful insight into TigerVNC
