at first let me try to describe your action(if I was wrong, please correct me ): boot laptop without any extern displays, then start X and plug extern VGA, after running %xrandr --output VGA --auto, VGA get a blank screen, and LVDS works fine, right?
I read the log file, and find some wrong TV detectiong info is involved.
So in order not to be disturbed by it, could you append the following configuration into your xorg.conf, test again and upload the Xorg log file with Modedebug option?
