My system used to display the Full HD resolution – the native, very well on the Karmic.
I upgraded my system to Maverick and the maximum 16:9 resolution X server supports is 1280×720.
As far as I can remember, I didn't have to do any changes for the display back when I originally installed 10.04.
From the lspci
, the graphics card I have is the one follows:
02:00.0 VGA compatible controller: ATI Technologies Inc Manhattan [Mobility Radeon HD 5000 Series]
How can I get back the high native resolution?

Ok, not sure if I should delete the question. But I am sure some people may face same issue, so I will just answer it anyway.
Disable the additional driver, enable it and then restart, boom, everything back to normal!
