This "initial brightness zero bug" is an ACPI problem and a work around
fix patch is headed for kernel 3.13. Chances are good that it gets
backported to kernel 3.12. Details at:
https://bugs.freedesktop.org/show_bug.cgi?id=71596

I think Bug https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1224415
is a duplicate of this one too.
