Symptoms You'll See Without This Fix

When you run hp-scan and choose the USB device (option 2), you'll get:

How to create a homemade VGA Adapter for a Sun Workstation's video connector

A Sun DB13W3 video connector

A Sun video connector (DB13W3). N.B. The image is flipped horizzontaly. Source of the image: Using A Sun 13W3-VGA Adaptor On A SGI Indy.

Pin K1, K2, K3 have been added by me for reference purproses, they refer to the outer shell of the video connectors.

N.B. This guide guide applies to Sun workstations only, SGI's implementation of the connector has a different pinout from the image attached above.
