Install TigerVNC server on Linux Mint 22 Wilma

Install TigerVNC package

$: sudo apt install tigervnc-standalone-server

Configure/create ~/.vnc/xstartup file

$: mkdir -p ~/.vnc
touch ~/.vnc/xstartup
chmod +x ~/.vnc/xstartup

Check what is the exec command to start the Cinamon session

$: ls /usr/share/xsessions/

It should show somethig like:

u1@m0:~/.vnc$ ls /usr/share/xsessions/
cinnamon2d.desktop  cinnamon.desktop

Let's use cinnamon.desktop and check the contents

$:  /usr/share/xsessions/cinnamon.desktop

It should show somethig like:

[Desktop Entry]
Name=Cinnamon
Comment=This session logs you into Cinnamon
Exec=cinnamon-session-cinnamon
TryExec=/usr/bin/cinnamon
Icon=
Type=Application

The Exec command is cinnamon-session-cinnamon. Edit ~/.vnc/xstartup, and add contents below. Note we are using cinnamon-session--cinnamon:

#!/bin/bash
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS
exec cinnamon-session-cinnamon

Now run vncserver. On the first time you run it, it will ask to define the server password.

$: vncserver -localhost no :1 -geometry 1024x768

This runs the server and listens on all interfaces on port :1 (or 5901) with a screen dimension of 1024x768.
