Xinerama on Ubuntu 8.10 with Nvidia

[Ninds]

I have Xinerama working on my box with a Nvidia card.
My xorg.conf follows




# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 1.0 (buildd@crested) Mon Nov 3 08:46:04 UTC 2008

# xorg.conf (X.Org X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# Edit this file with caution, and see the xorg.conf manual page.

I initially installed the nvidia settings utility and went through the setup. In the resulting xorg.conf there is a line under the section "Serverflags" that reads


Option "Xinerama" "0"


I changed it to


Option "Xinerama" "1"


I hope this helps others, I have seen numerous people have issues with this online.
