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: http://en.gentoo-wiki.com/wiki/Nouveau#Framebuffer_does_not_fill_screen_or_is_larger_than_screen 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) Version-Release number of selected component (if applicable): Fedora 17 Linux 3.4.3-1.fc17.x86_64 How reproducible: Very Often Steps to Reproduce: 1.Just boot with the new kernel Actual results: output is bigger than my physical Display size Expected results: Additional info:
It is fix in the new kernel Version: 3.4.4-5.fc17.x86_64 I am closing it.
