According to my graphics here in ubuntu, i ahve intel ironlake mobile x86. does graphics have anything to do with the VGA1 output not connected in xrandr.I have read documentations and followed steps using the xrandr --output VGA1 --right -of LVDS1 but nothing happened. I want the unit to be plug n play...please help me. (Hardware)
