I’ve had way too many problems trying to run tightvncserver on Rpi3 under Kali that I decided to rip out the tighvncserver and try vnc4derver daemon. The main problem was that it would give me a blank screen with a X cursor randomly. It would work fine one day and wouldn’t work the next time, and nobody had fiddled with any configurations to make it go wonky.

• SSH onto the Rpi3/Kali
• apt-get update
• apt-get install vnc4server
• After that run commands as shown below

root@Kali:~# vncpasswd

root@Kali:~# vncserver :1

    . /lib/lsb/init-functions
    case "$1" in
    start)
    log_action_begin_msg "Starting vncserver for user '${USER}' on localhost:${DISPLAY}"
    su ${USER} -c "/usr/bin/vncserver ${OPTIONS}"
    ;;
    stop)
    log_action_begin_msg "Stopping vncserver for user '${USER}' on localhost:${DISPLAY}"
    su ${USER} -c "/usr/bin/vncserver -kill :${DISPLAY}"
    ;;
    restart)
    $0 stop
    $0 start
    ;;
    esac
    exit 0

Conclusion

Now go ahead and install a VNC viewer on your main machine and connect to appropriate IP given to the Rpi3, for e.g. 192.168.1.10:1
