[New Found!] 1. When I set to others instead of 1440x900 (16:10) or 1280x800 (16:10) revolutions, the black bar must disappear. 2. When I set to 1440x900 revolution, the black bar must exist.
The display area is not fit to my monitor(1440x900) and there is a black bar at the top of my screen. The bottom of the display area can't be displayed. How can I deal with this problem?
I wonder if the problem come from the lack of display card (MSI R4770 Cyclone) driver but I don't know how to install it. Do I need to install it?
Ubuntu Version : 13.10
