[SOLVED]Can't get Dual Screens to run properly on a IBM T42

hey guys,

i seem to have a little problem here. i'm trying to get an external TFT screen to run from the vga-out of my thinkpad. the screen on the laptop supports a default resolution of 1400x1050 pixels, the TFT should operate at 1280x1024. when i plug in the TFT monitor, my screen is automatically cloned to it and operates at 1400x1050 pixels, which looks really, really ugly.

so, when i do 'xrandr --output VGA-0 --right-of LVDS' it works okay, but the TFT STILL operates at 1400x1050. do i have to add something special to my xorg.conf? what i have now is:

Section "ServerLayout"
        Identifier     "X.org Configured"
        Screen      0  "Screen0" 0 0
        Screen      1  "ExtTFT" LeftOf "Monitor0"
        InputDevice    "Mouse0" "Section "Monitor"
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

<--snip-->

Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Monitor Vendor"
        ModelName    "Monitor Model"
        Option       "DPMS"

Section "Monitor"
        Identifier "ExtTFT"
        Option "DPMS"
EndSection

<--snip-->

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes "1400x1050"
                Virtual 2800 1200
        EndSubSection
EndSection

Section "Screen"
        Identifier "ExtTFT"
        Device "Card0"
        Monitor "ExtTFT"
        SubSection "Display"
                Depth   24
                Modes "1280x1024"
        EndSubSection
EndSection

Output of 'xrandr -q' is:

Screen 0: minimum 320 x 200, current 1400 x 1050, maximum 2800 x 1200
VGA-0 connected 1400x1050+0+0 (normal left inverted right x axis y axis) 338mm x 270mm

DVI-0 disconnected (normal left inverted right x axis y axis)
LVDS connected 1400x1050+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1400x1050      50.0*+

Thanks!

EDIT: Okay, fixed this just by using 'xrandr --output LVDS --mode 1400x1050 --output VGA-0 --mode 1280x1024 --right-of LVDS', sorry.
