To get the native resolution working on each monitor I had to create an xorg.conf like this when using the live CD:
Section "Device" Identifier "Videocard0" Driver "nouveau" EndSection Section "Screen" Identifier "Screen0" SubSection "Display" Depth 24 Virtual 3000 2000 EndSubSection EndSection
This is my xrandr after using the the above config:
Screen 0: minimum 320 x 200, current 2960 x 1050, maximum 3000 x 2000 DVI-I-0 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 474mm x 296mm 1680x1050 59.9*+ 1400x1050 60.0 1280x1024 75.0 60.0 1280x960 60.0 1152x864 75.0 1024x768 75.0 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 56.2 640x480 75.0 72.8 75.0 66.7 59.9 720x400 70.1 DVI-I-1 connected 1280x1024+1680+26 (normal left inverted right x axis y axis) 338mm x 270mm 1280x1024 60.0*+ 75.0 60.0* 1280x960 60.0 1152x864 75.0 1024x768 85.0 75.0 70.1 60.0 832x624 74.6 800x600 85.1 85.1 72.2 75.0 60.3 56.2 640x480 85.0 75.0 72.8 75.0 66.7 59.9 720x400 85.0 70.1 640x400 85.1 70.0 640x350 85.1
