Sorry can't help you more. I am trying to get dual monitor to work and no luck so far.

I did figure out how to change it so the boot up automatically boots windows instead of ubuntu.

in Ubuntu:

go to a terminal screen:
type sudo gedit
if it asks you for your password, enter your root password.

Then browse to root/boot/grub

open up menu.lst

change the default 0 to default 3 or 4, you count everything in the menu starting with zero. My windows is in spot 4, many users are on 3.
Just adjust according to your system. Then save and the next time you boot windows will be the default boot OS.
