Dual monitors in Ubuntu Karmic -- a revised xorg.conf

A week or so ago, I posted a /etc/X11/xorg.conf that worked very well for me to give twinview dual monitor operation in Ubuntu 9.10.
Of course, many of the lines of code were unnecessary and I've now cut the Display part of the xorg.conf file down to a minimum. This works just as well as the previous version.
Here it is:

Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
Option "TwinView"
EndSection

Section "Screen"
Identifier "Screen0"
Option "TwinViewOrientation" "DFP-0 LeftOf CRT-0"
SubSection "Display"
Depth 24
EndSubSection
EndSection
