ubuntu 9.10 nvidia monitor settings dont save

Was having the issue of not being able to save my dual monitor configuration with a default installation of 9.10. The xorg.conf seems to be unable to be parsed by nvidia-settings tool, so to get around this we can run nvidia-xconfig to reset the config file to something that it can work with.

sudo nvidia-xconfig

after that

gksudo nvidia-settings

and we can save to xorg.conf successfully.
