Description vive.marseille 2011-05-17 12:02:52 UTC 
Version:           4.4 (using KDE 4.4.5) 
OS:                Linux

When I set a new resolution in xorg.conf such as :

Section "Device"
        Identifier "Card0"
	Driver "intel"
EndSection
Section "Monitor"
	Identifier "LVDS1"
EndSection
Section "Screen"
        Identifier "Screen0"
	Monitor "LVDS1"
	Device "Card0"
        SubSection "Display"
                Modes "800x600"
        EndSubSection
EndSection

I got lots of DDC messages in /var/log/Xorg.0.log :

Printing DDC gathered Modelines:
Modeline "1280x800"x0.0 69.30 1280 1328 1352 1416 800 803 809 816
Modeline "1280x800"x0.0 46.22 1280 1328 1352 1416 800 803 809 816

Then, after login via kdm, sometimes KDE freezes and open hundreds dialog boxes saying "Screen configuration has changed"

Try to add Option "NoDDC" in xorg but according to http://manpages.ubuntu.com/manpages/maverick/man4/intel.4.html , this option is no longer available for chipset CM45

Laptop : Dell Latitude E5500 Chipset CM45

Reproducible: Sometimes

Steps to Reproduce:
Put a new resolution in /etc/X11/xorg.conf

Actual Results:  
KDE sometimes freezes and can't be used
