[xubuntu] Extended Display Not Working ( I've already researched, please help)

view story

http://ubuntuforums.org – So after setting up Xubuntu in my Acer Aspire One netbook everything runs smoothly. However I normally use this netbook (1024x700 Resolution) together with a larger VGA desktop screen (because the netbook's screen is so darn tiny) and use the VGA as my main and the netbook's screen as my secondary screen. Anyways. after setting up ARandR and trying to extend the displays I came wtih the weirdest thing. Extending the two screens side by side causes all windows to be shadowed in a way that they look dark grey and you can barely read anything. I've been reading around for people with similar iss (Hardware)
