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.
Hi Bernd -
The i915.invert_brightness parameter has only ever been needed on some gen4 Acer laptops; I suspect this is something else.
Please drop that parameter, and try one of the v3.13-rc kernels or video.use_bios_initial_backlight=0 module parameter.
For completeness, the reporter replied privately that video.use_bios_initial_backlight=0 works.
Jani.
If those don't help, please file a bug on Product=DRI, Component=DRM/Intel as instructed in [1].
BR, Jani.

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
