Commads I used to install VNC on MBP12

install tigerVNC
$ sudo apt install tigervnc-standalone-server

first time running the vnc server. It will ask you to create passwords
$ vncserver

now turn off the service to configure
$ vncserver -kill :1

create the xstartup file and manage the permissions
$ touch ~/.vnc/xstartup && chmod +x ~/.vnc/xstartup

add the below script to the xstartup file
$ vim ~/.vnc/xstartup

        #!/bin/sh
        #Start up the standard system desktop
        unset SESSION_MANAGER
        unset DBUS_SESSION_BUS_ADDRESS
        /usr/bin/startlxqd
        [ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
        [ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
        x-window-manager &

see open ports to make sure vnc has a listening port on 5901
$ ss -tulp4

$ vncserver -geometry 1920x1080 -localhost no :1
