Headless Ethereum Miner Setup - NVIDIA

Reed Slaby, March 2018

Having grown tired of wasting a perfectly good monitor on my ethereum mining rig, I finally decided to replace the Ubuntu Desktop 16.04 installation with Ubuntu Server 16.04. Many of the gtutorials available at the time of this writing range from unecessarily complicated to flat-out wrong. This guide is intended to address many of those shortfalls.

Prerequisites

To complete this guide, you should already have:

• Basic knowledge of Linux
• An Ethereum wallet
