Well... it's clear.

Starting with the resolution:
1366x768 (found on google)
 the x value is not a multiple of 8. 1368 is!!!!
gtf gives this line:
   Modeline "1368x768_60.00"  85.86  1368 1440 1584 1800  768 769 772 795  -HSync +Vsync

My xorg.conf is not complete so I wrote the section screen and monitor
My complete Xorg configuration file is

------  begin xorg.cong
# Xorg configuration created by livna-config-display

Section "Files"
        ModulePath   "/usr/lib/xorg/modules/extensions/nvidia"
        ModulePath   "/usr/lib/xorg/modules"
EndSection

Section "ServerFlags"
        Option      "AIGLX" "on"
EndSection

Section "Device"
        Identifier  "Videocard0"
        Driver      "nvidia"
        Option      "AddARGBGLXVisuals" "True"
EndSection

Section "Extensions"
        Option      "Composite" "Enable"
EndSection

Section "Monitor"
        Identifier      "Acer Aspire 5739G"
        # 1368x768 @ 60.00 Hz (GTF) hsync: 47.70 kHz; pclk: 85.86 MHz
        Modeline "1368x768_60.00"  85.86  1368 1440 1584 1800  768 769 772 795  -HSync +Vsync
EndSection
Section "Screen"
        Identifier "Default Screen"
        Device "Videocard0"
        Monitor "Acer Aspire 5739G"
        DefaultDepth 16
        SubSection "Display"
         Depth 16
         Modes "1368x768_60.00" "1366x768"
        EndSubSection
EndSection
-------- end xorg.conf

Nothing changes, but in the log file I can read extracting only the warning

I can provide the entire xorg log if it can be usefull.
Maybe I fail to specify the Screen modes, but I'm not an expert of xorg
and I read some examples from google.

Tnx to all
