you don't specify any orientation for screen2 to in your config:
        Screen          "Screen0"
#        Screen          "Screen1"
        Screen          "Screen2"

should be something like:
        Screen          "Screen0" 0 0
#        Screen          "Screen1"
        Screen          "Screen2" RightOf "Screen0"
