Well, not that sort of dual, but with the addition of an overpriced, and overly large wall-wart-ed power adapter, I now have both my Windows and Linux box with dual monitors. The KVM that doesn’t like wireless mouse from a few months ago gets it’s power from the ps/2 connection, but had a 9V connection (which it’s manual stated wasn’t needed). Of course the other, working KVM is plugged into the PS/2, so I wandered into town to pick up a power adapter. I now have even more of a mess of wires behind my computer, and have to hit a button to swap the second monitor around, but it gives me an extra 1280×960 pixels of deskspace under XP.
