Description Vivek Dasmohapatra 2015-11-16 21:54:43 UTC
Several users on the 01.org linuxgraphics forum have reported a black
screen when booting Inte NUCs, with various approaches solving the
problem, including:

 - switching to a DVI-DBI cable from some other type
 - changing the connected monitor
 - downgrading from a 4.x kernel to a late 3.x series kernel

Since it's not clear if these are all the same bug these reports
are being collected here at Intel's request so they can be investigated.

The main discussion thread:

https://01.org/linuxgraphics/forum/graphics-installer-discussions/nuc5i3ryh-black-screen-debian

Some solutions from that thread:


    Using a Dell monitor connected via a VGA cable 
    to a miniDisplayPort to VGA adapter. After 
    Switching to a Samsung monitor hooked up via DVI and a miniDisplayPort
    to DVI adapter, all my problems went away

    Fresh install and  dnf update which installed 4.1.7-200.fc22.x86_64
    reproduced the problem. 
    With this as the machine's current state 4.0.4-301.fc22.x86_64
    works fine.

    I went through the
    https://wiki.archlinux.org/index.php/Intel_graphics
    and couldnt get it working on debian testing. 
    NB: Probably kernel 4.1 at the time.
    ... well I though of trying stable kernel... added all apt source 
    entries of stable repos and added 3.16 kernel... AND IT WORKS.

Please add drm.debug=14 module parameter and attach dmesg all the way from boot to the problem.

Please try v4.3 or later kernel.

It's likely this has to do with DP->VGA dongles, based on the reports.

Elio,
Could you have a try and provide the log.
Comment 3 Elio 2015-12-09 19:42:49 UTC
I'm trying to reproduce the issue stressing the system, no positive results so far, i will try to stress the system a few hours and see what happen.
Comment 4 Elio 2015-12-10 15:38:42 UTC
I'm not able to reproduce the problem so far, my configuration:

Ubuntu 15.10 with 3.10.26 Kernel

Stressing the system with stress for more than 8 hours:

"stress -c 10 -m1 --vm 2 --vm-bytes 8192M"

All cpus are over 100% 
Memory (7.7 GiB) 100%  Swap(7.9 GiB) 50%

Using a Dell Monitor thourgh VGA with a Mini Display - Vga Dongle.

Brand:  Startech.

I'm just wondering if we can get the dongle brand since it seems to be difference on the setup
Comment 5 annonm 2016-01-15 18:25:24 UTC
I have a NUC5i7, not an i3, and do not suffer from the problem. My hardware does identify itself as i915. Let me know if I can be any use in testing.
Comment 6 ravi mannan 2016-01-18 02:11:42 UTC
I am having the same problem. Here's some info on my configuration.
Let me know if you need more info. The 2nd monitor connected via hdmi is the one that blacks out, not the laptop screen itself.
No, it's not a problem with my hdmi cable or monitor, those both work on with another computer.

Comment 7 ravi mannan 2016-01-25 23:01:06 UTC
I have a dual boots system. I've been using Windows 10 and I am not seeing this problem. It is not the cable , hdmi port or monitor.

It doesn't seem to be happening at a lower resolution of    2560x1080:

HDMI1 connected 2560x1080+1920+0 800mm x 335mm
   3440x1440      50.0 +   30.0

Seeing the same issue with a 4.6+ kernel, NUC DN2820FYK. I'm using a HDMI/DVI dongle.
Comment 11 Jani Nikula 2016-06-21 14:42:43 UTC
Please try drm-intel-nightly branch of [1] and report back.

So is that working or not?

No, same behavior.

Hello Aristeu,

I was trying to replicate the issue in my nuc here, but i wanst possible, could you share all the hardware configuration that you are using? I'm loosing something important.

Currently i was able to setup this platform with 3 monitors, 1 of them 4k. 

It should be great if you can post all your hardware in order to dismiss cables/monitors. etc.
Comment 16 Elio 2016-08-29 20:24:48 UTC
I just forgot to say that i was trying to reproduce the issue with Kernel 4.8.0
