Easy VNC Setup (Tested with RealVNC and TightVNC)
This is a great little method that I found on the net. Kudos to whoever wrote it.
Installation: Create file /etc/axvnc
Paste the code below in "axvnc". (you may have to make a few changes based on errors. I got it to work and I don't know what I am doing)
Set execute permission (chmod +x /etc/axvnc).
Using: run /etc/axvnc from the graphical Unix/Linux console.
