Targus ACP50US USB VGA Configuration Help

Hello,
I am trying to get the video card on a Targus ACP50US to work on my Dell XPS M1210. I was able to find on the net that this device works Screen 1with the sisusbvga drivers from xorg.conf. After a little bit of tinkering, I was able to get a display from my device but all it shows was a gray screen but my primary screen displayed fine. I was wondering how I can get my ACP50US to work and able to use it as a primary display when I hook it up to my laptop. Here’s my config so far. Any suggestions? Thanks!!!

Jose
