I’ve have project that requires the use of the 7th gen intel NUCs and i’ve stumbled with an issue with the video acceleration on the debian jessie docker image, which makes my app crash whenever the video driver tries to display anything too intensive (a video or any animation in css or even a big image on a 1080p screen).
Steps to reproduce issue
Flash the resinOS provided by the resin dashboard (2.0.9+rev1 as the time of this writing) .
Using Resin/Electron as a base i make the necessary adjustments in the Dockerfile.template to make video output work :
use docker image base resin/intel-nuc-node:8
remove the line: xserver-xorg-video-fbdev \
add RUN echo deb http://http.debian.net/debian jessie-backports main contrib non-free > /etc/apt/sources.list.d/jessie-backports.list
Put some CSS 3d animation or video on the electron app for video acceleration testing
Push the app to the repo and let the NUC provision itself.
Expected result
Webview to start with video acceleration.
Actual result
App crashes with different errors, among them some of the like:
[intel_init_bufmgr] Error initializing buffer manager.
xinit: connection to X server lost
[WARNING:audio_manager.cc] Multiple instances ofAudioManager detected
Other information
This was just for testing but i also added in one instance intel_iommu=igfx_off in the grub.cfg file. (needless to say it didn’t help).
Disabling hardware acceleration & webgl in electron config just makes it so the app is visible until you interact with it and some animation happens then the app crashes.
Do you mind posting a full log from one of the crashes (or as much as you are able to get)? It could be interesting to see what else is happening around that time.
I’m also curious as to whether you have tried this outside of resin.io using the same Debian version and firmware – if so, does that work?
If I understand you correctly, the video is working properly up to the point that a large image or a lot of animation is happening, at which point it crashes. If it were something simple like a driver failing to load I’d expect to see a failure before getting any video at all.
I’ll ask one of my colleagues with a NUC to see if they can reproduce this.
@Victor actually, it seems like the first thing to check is to make sure you are on the latest version of resin-electronjs. There was a pull request about two weeks ago to fix a similar issue: https://github.com/resin-io/resin-electronjs/pull/45
Can you verify that you are on the latest upstream code for resin-electronjs?
Here is a log with the hardware acceleration turned off in electron:

Yes, and its seems is a known issue with debian jessie, that’s why i had to use a backported driver because it doesn’t have support for skylake processors. and if i enable hardware acceleration the app crashes without even displaying anything on screen.
i am, yesterday i cloned a new repo just to try that
Welp Akismet didn’t showed up my post, so i’ll answer again
i was on the last commit of the repo (yesterday i cloned a new instance testing stuff), but that was when i was trying to install the backported drivers so i think i just messed everything up, i just tried adding the PR change to my code and… it doesn’t crash! but that doesn’t fix the hardware acceleration issue so the performance is very poor (tearing and choppy animations)
Hi @Victor , I am investigating the issue, and I have a question for you:
how did you enable hw acceleration in your project? I did in the past with a branch called intel which has now been rebased so it also includes the fix for the crash with large images etc: https://github.com/resin-io/resin-electronjs/tree/intel
Hello @curcuz, i’m sorry for the late reply. i’ve been busy with some other parts of the project, and now i’m retaking on this issue.
actually when i use that branch i get this issue with X: (EE) no screens found. and i get no display on the monitor.
as my understanding goes i think for Kaby Lake (and any Intel graphics since Broadwell), you need to install a new kernel and firmware from Jessie backports; for proper HW Accel.
right now i have a functional demo that does not crash but with very poor performance (which completely ruins the purpose for using a intel nuc in the first place)
I’m not sure if this issue is still on-going or not. @Victor, if you could let us know whether your using of the backported driver in the dockerfile has solved the issue, or whether thats more of a “I’m already trying the backport, doesn’t solve it” sort of a post.
Sorry!, i’ve been out of commission for quite a few days, and yes it is an on-going issue, on the OP i wrote that i did some adjustments in the dockerfile to add the backported driver. so it was a “I’m already trying the backport, doesn’t solve it” kind of a post
but that doesn’t fix the hardware acceleration issue so the performance is very poor (tearing and choppy animations)
