Hi.
This also affects my system (1920x1080 and 1680x1050 display).

When I reboot, each time the desktop wallpaper for the smaller monitor
(1680x1050) appears fine.
The larger monitor is running 1920x1080 but the desktop wallpaper appears to be

card for a 5770 and have found the same issues.
The same dialog pops up when running Unity-2D and trying to set the
"Displays" app to extend the desktop across both monitors.
