Vincenzo Ciancia,

To confirm with you.

A1 is after starting Xorg ,before connect VGA
A2 is after connect VGA and runing "$xrandr --output VGA --auto"

B is vga is pluged before boot

Neither A1 nor A2 case make your LCD and external VGA work at the same time, while B case, LCD and VGA can both work at the same time.

Is the above statement right?

If that's true, one interesting thing is, the reg_dump in comment# 23 is identical with B case, while comment# 23 doesn't work while B works... This senario is identical with bug# 16777. It seems vbios did something we are not aware...
