So I have a lab setup with multiple testing systems, each with a different kind of video card, and a cluttered desk of keyboards, mice, game controllers and joysticks. There's a mass of braided/tangled/ratnested cables from all these peripherals leading to the computers behind my desk.
By the advice of some X.org devs I installed Synergy and set every test system on a loop. Each continues to have it's own GPU+Monitor, their own GNU/Linux distro for packaging, but I only need one keyboard and one mouse to move between them.
Kudos guys, what's left of my sanity thanks you!
