Hi everyone,
I have seen that on lkml, too, and experience it myself: Suddenly the
backlight is gone:
[ 2.018622] No ACPI video bus found
up to 2.6.37 there was one ...
There are some other things regarding i915/drm in my dmesg:

That is with latest git kernel.
Anything else needed here?

BOOK There is a theory which states that if ever anyone discovers
exactly what the Universe is for and why it is here, it will
instantly disappear and be replaced by something even more
bizarrely inexeplicable.
There is another theory which states that this has already happened.
