CID: 201202-10511 Dell Inspiron 5420

After boot to desktop, there will be an "Unknown" display work as an extended display on this system with 12.04.5

The problem with this issue is that you will be able to move the cursor out of your screen, even open an application on the extended display.

Steps:
1. Install 12.04.5, boot to desktop with no external monitor connected
2. Open the "Display" utilty, check whether there is an "Unknwon" display

Expected result:
* There should be only a "Laptop" display

Actual result:
* An "Unknown" display available
