nvidia xorg.conf upgrade
My xorg.conf broke when I upgraded to ubuntu 12.10 because of the upgrade of nvidia-current from 295.40-0ubuntu1.1 to 304.51.really.304.43-0ubuntu1. I'm running 2 graphics cards and 3 monitors, rotated, as one big display.
Here is the new xorg.conf file, showing the 'metamodes' syntax and the DPI override I needed to get the right size fonts:
The interesting lines are these for the screens:
Option "metamodes" "DFP-0: nvidia-auto-select @1050x1680 +0+0 {Rotation=right}, DFP-1: nvidia-auto-select @1050x1680 +1050+0 {Rotation=right}"
DisplaySize 720 540
Option "UseEdidDpi" "FALSE"
