Bug Description
Binary package hint: xserver-
Laptop has 1400x1050 internal panel and is attached to an external screen which is 1680x1050. If I set the screens to mirror then I can have the same on both screens and this works fine. If I set them not to mirror then the secondary (external) screen is black but I can _just_ about move the mouse onto it. i can see the cursor on the second screen but its not usable because it only goes a few pixels onto the second screen before hitting a 'wall'.

I can reproduce this and have tracked it down to a change in the ddx between db586624d4f2908 d2a998ba87fe0ae 31c10f46b91 and 41684d54592cf93 554a4d6534e7ea7 4562b1798.
