Dear all,

Thank you very much for the tips. After a lot of struggle (and many,
many stupid mistakes)  I've  managed to get the dual monitor.
The only issue is that it seem impossible to get the screen resolution
right. The screen of the T61 is a  1280X800. The external  monitor is
a 19 inches  westinghouse L2046NV , that is  capable of 1400x 1050.
However  I am stuck at 1280*800 and the screen looks awful. Probably I
am making a stupid mistake.
My current xorg.conf:

Section "Device"

        Identifier      "Intel Corporation Mobile GM965/GL960
Integrated Graphics Controller"

        Driver         "intel"

        Option          "monitor-VGA" "foo"

        Option          "monitor-LVDS" "bar"

	BusID		"PCI:0:2:0"

        #Option         "monitor-TMDS-1" "dvi"

EndSection



Section "Monitor"

        Identifier      "foo"
	Vendorname	"Plug 'n' Play"
	Modelname	"Plug 'n' Play"

        Identifier      "bar"

        Option "LeftOf"  "foo"
        Option "PreferredMode"  "1280x800"


EndSection



Section "Screen"

        Identifier      "Default Screen"

        Device        "Intel Corporation Mobile GM965/GL960 Integrated

        Monitor       "bar"

        DefaultDepth  24

        SubSection "Display"

                Depth          24

                Virtual                 3000 3000

        EndSubSection

EndSection

# And the result of xrandr -q

 Any suggestion?
 Thank you very much,
