I have two computers, my main computer and a second computer that I have set up elsewhere in my vicinity. The main computer has a dual display, and the second computer has a monitor set up to it. Basically what I'd like to do is set them up so that all three monitors are part of one display.
I am using Linux on both computers. I believe the answer lies somewhere in using Xdmx, but nothing I have tried has worked so far. I've followed through both this and this and neither one has proved satisfactory.
