Comment 0 for bug 656855

I'm extending my laptop monitor with a native resolution of 1366×768 with an external display with a native resolution of 1280×1024. This situation is poorly handled.

Here's a representation of my setup, which I mirrored in the Monitor configuration:

╚═════════╧═══════╝

▓ laptop monitor
▒ external monitor
░ area that is not covered by any monitor
═ shape of the virtual desktop
─ shape of the area that is actually covered by monitors

The ░ area should not be eligible for mouse placement and desktop icon placement, but it is in Ubuntu 10.10 under GNOME. (Other desktop systems may also be affected but I didn't try them yet.)
