I have got triple monitor setup, with two Nvidia graphics adapters. I wanted to set it up the same way as it is configured when I run Ubuntu under VMware - e.g. each screen allows to separately maximize one application. At the moment I am only able to configure the screens so they are all white, and when I move cursor it changes into black cross. Below is my setup - there is only single screen per adapter is configured right now (to nail down the problem - on single adapter with two monitors I am able to enable Twinview, but it is not what I am looking for). I know that Ubuntu is completely fine working with 3 screens, because I have it running in VM on the same setup. I just do not know how to make it run on real hw. Please, help, I do not want to run Windows + VM just to run Ubuntu with multiple screens.
