I know that the new 5xxx series cards from ATI are capable of powering up to 6 monitors, but I was curious if anyone had any such luck setting this up under linux. I actually only have three monitors that I am interested in using, but three is the point where the previous generation video cards started to get a little buggy as a result of needing multiple video cards. Is the linux support for this capability any good at this point, or is the Eyefinity support really only for windows at this time.
UPDATE 4/7/11: Since this page is the top hit on Google for linux eyefinity, I'd like to update it with more up-to-date information. I recently purchased a 5870 card, and using the drivers from ATI I was able to get eyefinity working much easier than I had expected. The driver even allowed me to rotate one of my monitors, something I had wanted to do for a long time. This has proved to be a much cleaner solution for my scenario than dual videos cards and xinerama.
