Description of problem:

I  updated my kernel few days ago from 3.3.7 to 3.4.3-1 ( both fedora package). From that time, both X and Frame buffer outputs  are bigger than my Screen monitor. I am using nouveau. KDE display setting is showing that resolution is about 2400X2000 ( Not the exact number as I am not using that kernel now). But my native display resolution is 1920x1080. 

I searched and found this: 

I tried to set the display resolution by adding  display=LVDS-1:1920X1080 to kernel param in Grub. It actually works and changed my resolution but still the screen is still bigger than my monitor and I am being shown only the top left part of display. When I boot with the old kernel everything is OK. Here is lspci: 

01:00.0 VGA compatible controller: nVidia Corporation GT216 [GeForce GT 330M] (rev a2)
