I see.  Thanks.

Not all black screens have the same cause.

In particular, if I understand correctly then you specifically ruled
out the cause of bug#680737 by checking that increasing the backlight
does not restore the screen image.

My response about LVDS versus S-Video was silly --- I should have
read more carefully.  But all too often bug reporters pile on
reporting distinct problems (sometimes with identical symptoms!) to
the same report and it becomes very, very difficult to untangle them
and solve them all.  When it comes to hardware-specific bugs, I
speak from experience in saying that when the preferred practice is to
err on the side of filing a separate report there is a good reason for
that.

Of course all that is less important than the crucial thing: thanks
for testing and reporting your findings!  Without you, the OS would be
buggier.
