Bem, eu consegui trabalhar, mas não como eu queria. Eu uso o xrandr em ~ / .xprofile para configurar as telas quando eu faço o login, o que é bom, mas eu não entendo porque isso não funcionará no xorg.conf.
Aqui está o meu perfil .x:
xrandr --output mon0 --pos 528x0
xrandr --output mon1 --right-of mon0
xrandr --output mon2 --below mon1
xrandr --output mon3 --left-of mon2
E aqui está o que eu acabei no xorg.conf:

Eu gostaria de conseguir que o X trabalhasse sozinho sem precisar do material xrandr, mas na tela de login, parece que todas as telas estão lá, mas apenas empilhadas umas sobre as outras e são espelhadas / duplicadas todos os monitores.
Não é grande coisa agora porque está funcionando, mas se alguém tiver alguma pista, eu adoraria ouvi-la ...
