Configuring VNC Server

The configuration is really simple, dont need to changes or edit a lot file.

1. Create User

Never run the VNC as root because it will find a way to break your system. If you already had a normal user, skip this step.

sudo adduser atetux

2. Set VNC Password

To setup VNC password for user created on step 1 above run vncpasswd


don’t re-use your login password here, use another one. Make sure you only input 8 character long or less password, because that the only supported by VNC.
