Thanks for pointing that out.
Finally I solved my issue with

    -  xrandr which returned

Screen 0: minimum 320 x 200, current 1280 x 800, maximum 32767 x 32767
LVDS1 connected 1280x800+0+0 (normal left inverted right x axis y axis) 261mm x 163mm
VGA1 connected (normal left inverted right x axis y axis)
   1280x1024      60.0 +   75.0  

And then

xrandr --output LVDS1 --preferred --primary --output VGA1 --preferred --right-of LVDS1
