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

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.

If those don't help, please file a bug on Product=DRI,
Component=DRM/Intel as instructed in [1].

BR,
Jani.

For completeness, the reporter replied privately that
video.use_bios_initial_backlight=0 works.

Is it possible for the reporter to test a v3.13-rc kernel? That param is
removed in v3.13 after I did some clean up so it would be great to know
if v3.13 kernel still works for him.

Thanks,
Aaron
