Here should solve the problem (I assume you're using the proprietary 
nvidia drivers):

If you don't have the buggy Samsung lcd screen, just add :

Option "UseDisplayDevice" "DFP-0"

in Section "Device" of /etc/X11/xorg.conf

So yours might be :

Section "Device"
Identifier "Videocard0"
Driver "nvidia"
Option "AddARGBGLXVisuals" "true"
Option "UseDisplayDevice" "DFP-0"

(since you won't be using the custom edid)


PS : Please tell us how the laptop sleeps/hibernates both in feisty and 
gutsy (for me in feisty it could only sleep) once you install gutsy.
