Hello,
i got a new Notebook with an Intel Core i7-3689Y whit a Intel HD Graphics 4000. I got a blank screen while booting but I could use ssh. This happened each time, when I enabled CONFIG_I915_KMS in the kernel config (modeset=1). Setting the option "invert_brightness=1" solved the problem.
I attached the "lspci -s 00:002 -nn -v" output. I use the gentoo kernel 3.10.17.
I hope this helps you a little bit.
Kind regards,
Bernd Lehmann
