For a start, remove all of these lines:

InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Section "InputDevice"
# generated from default
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection
Section "InputDevice"
# generated from default
Identifier "Keyboard0"
Driver "kbd"
EndSection

It's all provided to X by hal.


Then provide the output of "xrandr --verbose"

My reply asked that you provide the output of:
Quote:
$ xrandr --verbose
You have not.

Are you sure you have both screens connected? That output suggests that only one is connected and it has a resolution of 1360x1248.

Perhaps the card is not properly reading the EDID data from the monitor to know what resolutions it will take. Can you try specifying the model of the monitor in nvidia-settings, generating a new xorg.conf and then restarting X with that new configuration?

What type of monitor did you specify?

I do recall once having to mock up a fake EDID file to give to the driver because EDID was working but not getting the right information.

Did you *save* the setting by generating a new xorg.conf in nvidia-settings and then replacing the old one?

why in the Nvidia-settings the model option still in
CRT-0(CRT-0 on GPU) >> bad resolution
Samsung SyncMaster (CRT-1 on GPU-0) >> good resolution

According to my googling, the Samsung SyncMaster 943SNX has a Horizontal Frequency Bandwidth of 31-80Hz and a Vertical Frequency Bandwidth of 56-75 MHz.
Try changing to:
