I have a triple monitor setup on Nvidia currently, but after having a number of difficulties with the Nvidia drivers, I'm thinking about jumping ship to AMD graphics cards with Eyefinity.
I would like the possibility to switch to a quad monitor setup down the road, assuming that the ATI drivers work reasonably after a few days of testing. Since many of the graphics cards require special "active" display converters to convert DisplayPort to DVI, I was wondering if it would be easier to install two lower end graphics cards in my system instead of getting a high end card that has 5/6 DisplayPort connectors. Currently I have 2 HDMI monitors, and one DVI monitor.
I don't need anything fancy in terms of performance; just the ability to run 3 (possibly 4) monitors at 1920x1080 w/ compiz enabled.
Is it possible to have multiple AMD/ATI video cards on an Ubuntu machine?
Update 2011-15-12: I have installed a single Radeon HD 6770 with 5 mini display port connectors, so I no longer have a need for multiple graphics cards.
