I have 2 monitors both 19" widescreen 1440x900, i used nvidia-settings to set up the displays, I am using the seperate x session option, What i want to do is change the monitor that it is using as the primary display to be secondary. I searched the forums and tried messing with xorg.conf a bit but i was unsuccessful. Anyone have any idea how to change the primary display.

The one i want as my primary is the hp monitor which is currently screen 1
The one i want as the secondary is the samsung which is currently screen 0

heres my xorg file.

Code:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings:  version 1.0  (buildd@palmer)  Sun Feb  1 20:21:04 UTC 2009
