I am very new to tightvncserver on Raspberry PI. So, I researched online and I am still confused. First, I came across this webpage How to setup tightvncserver on Raspberry PI website about tightvncserver and I did not find any option in the Raspi-Config to enable tightvncserver. So, I ended up manually installing tightvncserver and don't know how to start or set it up. I tried to connect to PI's tightvncserver using tigervncviewer and it refused to connect. Could someone please give me some guidance. I am running Raspbian Jessie.
I wrote up a how-to for TigerVNC, which you can easily modify for tightvnc. See https://github.com/gitbls/RPiVNCHowTo/blob/master/README.md. Oh, I just noticed that you’re using Jessie, not Stretch. I haven’t tested it on Jessie, since it’s old and moldy and no longer supported.
