Hi
Read the remarks at the end of this page.

As you can see from this page the x1200 is Not consider to be supported by Win 7.
Thus the reaction of Acer, and AMD. I.e., the concerned parties are "shying" away from dealing with the issue.
At the end of the page there is Vista drivers. Give it a try.
The first large file includes the drivers and the ATI control Utility.
The second one is just the Drivers.
Which one? It is your call.
