Looking at your xorg log, it only loads for the first gpu. Do you > have an xorg.conf that hardcodes the busid? > Indeed, I was wondering why nouveau is loaded only once by X A minimal xorg.conf like the following should do the job Section "Device" Identifier "Device0" Driver "nouveau" # Actual PCI location of first card/gpu BusID "PCI:3:0:0" EndSection Section "Device" Identifier "Device1" Driver "nouveau" # Actual PCI location of second card/gpu BusID "PCI:4:0:0" EndSection Additionally if you're planning to use three or more outputs you might want to setup xinerama/zaphod heads [1] > In any case, I'd highly recommend retesting with a new kernel and > xf86-video-nouveau (and maybe xorg-server).
