When I boot my (rather old) laptop with a VGA screen attached, the main LVDS screen goes totally black (with no backlight) at loading the module i915 and the VGA screen goes black (but one can see the backlight is on). When I boot without the VGA screen attached all is normal (and I can plug it afterwards). In the first case xorg does not start (or is not visible).
I have no problems with previous kernels or with the lts kernel if I pass the VIDEO=SVIDEO-1:d kernel parameters (otherwise the screen goes black when I attach no screen).
Anyone having such problams, any workaround. For the moment, I just use the lts kernel.
