Created attachment 97330 [details] dmesg from a 3.15 rc1 I have tried all the next kernels and even the one that comes by default in 14.04 but all leave to blank screen I have added the debug mode for intel drm and here is the dmesg from a 3.15 rc1 kernel (with the same behavior)
Created attachment 97331 [details] xorg.log on 3.15 rc1
Please grab the latest intel-gpu-tools from git, run intel_bios_reader and attach the file. Most likely a mipi dsi panel ...
Adrian try plugging in a VGA monitor into the laptop and try booting it up and see if you get video on the monitor.
Hello the laptop is quite far away , i will try when i will reach it (In a few weeks) For the moment it works without acceleration
Please try v3.16 or later, preferrably drm-intel-nightly branch from http://cgit.freedesktop.org/drm-intel
Thanks i will test it when i reach to the laptop location
I have a hard lockup with 3.16.3 from ppa I try now intel daily
Created attachment 107233 [details] dmesg with 3.17 intel daily ppa Still crashes
and here is the screenshot https://plus.google.com/u/0/+AdrianMariusPopa/posts/TnmNVZikzGf?pid=6065677879256010578&oid=105567297772267099132
Ugg, didn't capture the top part of the backtrace. Can you build a kernel from the drm-intel-nightly branch of git://anongit.freedesktop.org/drm-intel and see if it works? If not, and the machine crashes hard again so you can't capture the backtrace, please try blacklisting i915 at boot, then load it later on and see if that lets you capture the backtrace via ssh or something.
Timing out, hopefully this one is fixed now.
I will try tomorrow when i reach the laptop :)
Still got the blank screen in ubuntu 15.04 with 3.19 and 4.0 rc kernels 4.0.0-040000rc6 I install now and test intel daily linux-image-4.0.0-994-generic_4.0.0-994.201504020205_amd64.deb
Is the dmesg the same with current kernels? I.e. are you still seeing a crash of some kind? Or is it just a display init failure now giving you a black screen?

I suspect this is fixed, please try current v4.3-rc kernels or drm-intel-nightly.
I have tried the the kernel from ubuntu 15.10 but it still crashed (4.2.x) I will try the 4.3 kernel when i reach the laptop in November Now is mostly stable with an old 4.0x rc kernel (where stable means vesa and no acceleration and 800/600)
