I'm trying to setup my first multi-seating PC using Ubuntu 9.10. I'm using a Nvidia Geforce 9400 video card along with the Nvidia Settings driver.
It appears that I've gotten the video to output to two seperate X screens. However, my input devices are all tied to screen0! That is with the following strange exception:
Right after I bootup, Both keyboards appear to control screen1. However, they quickly loose control of screen1 and permanently gain control of screen0 when I press the WindowsKey & E or click the mouse button.
Here are the contents of my xorg.conf file:
Code:

This multi-seating project has been a goal of mine for a long time now. Please help me figure out what I may be doing wrong.
