I'm building myself a nice setup with a massive amount of screen real estate. Since I had/have problems with video drivers in the past. I'm asking for advise here first.

I want to connect at least six screens.

What are the best options? What are the pitfalls? I preferably would not like to use closed binary blob drivers.

usecase scenario: I'm writing a piece of software that has to interact with other systems. I would like to be able to see all of those systems, my code, lots of log files and documentation without the need to swap windows/screens. To just better see what im doing.
