I am using TightVNC viewer from Window7 to connect the Ubuntu machine. I got the error "Error in tightVNC viewer no connection could be made because the target machine actively refused it.
I do not have any firewall setup.
When i run, ps -ef | grep vnc:: i get

I am not sure where is the issue.
I tried connecting like, 171.69.35.33 171.69.35.33:5900 171.69.35.33::5901

sudo apt-get install x11vnc && x11vnc -storepasswd && x11vnc -usepw
From this moment on, you can already access the VNC. Next, you can execute:
sudo x11vnc -xkb -noxrecord -noxfixes -noxdamage -display :0 -auth /var/run/lightdm/root/:0 -usepw
This solved my issue.
