NUC7CJYH Linux/HDMI issues

I'm toying with my new NUC7CJYH with Linux (idea is to make replacement Kodi box out of it) and I have serious troubles trying to connect it to my TV. Things work OK when I connect it to my desktop DVI monitor via HDMI-DVI adapter - I can boot from Lubuntu LiveCD, install Linux and Kodi and video works fine. But when I connect it to my old tried TV box (50" Samsung regular full HD 1080 display) via HDMI thing immediately break. Here is what I see:

  • Splash screen shows up normally (showing "Intel NUC")
  • I can get into BIOS pressing F2 and it works fine too
  • Going into Linux boot I can see GRUB in text mode
  • When Linux switches to graphics mode TV does not show anything, in fact TV just says "No Signal" as if NUC does not send anything to HDMI.
  • This happens both with LiveCD on USB flash (latest Ubuntu 17.10) and with Ubuntu installed on SATA SSD.
  • I tried to play with BIOS settings changing every possible option, nothing helps
  • I also tried to change Linux video driver in X11 between intel/modesetting, does not help either
  • Even if TV does not show any picture I know that Linux boots and Kodi start OK, I can connect to the box with VNC and it shows expected picture, Kodi says it's configured for 1920x1080 display, just as expected.
  • From VNC I tried to change Kodi screen resolution, and that sometimes makes NUC to show picture on a TV, but it is not very consistent (works more frequently on lower resolution, but almost never for 1080p).
  • I tried it also on my other TV, 1080p LG, and it has the same problem.

I'm not sure what else to try, but to me it make my new NUC unusable (even before I get into audio over HDMI step which I expect to be a problem).

Does anyone see anything similar to my experience, or did you manage to make it work?

Your operating system is not supported on your NUC:

I'm new to NUC and still fairly new to Linux. But it seems like Intel is backing away from any desire to support Ubuntu or other linux distros.

There are tidbits of info on Linux support https://www.intel.com/content/www/us/en/support/articles/000005499/mini-pcs.html here and bios discussion https://www.intel.com/content/www/us/en/support/articles/000022600/mini-pcs.html here. But the looking at the very recently updated "https://www.intel.com/content/www/us/en/support/articles/000005628/mini-pcs.html Supported Operating Systems for Intel NUC" that you referenced -- Ubuntu is missing/removed since I queued last. Crazy :_)

Its understandable with the fractured nature of all the Linux distributions and significant changes within Ubuntu coming. But the terms "mini pc kit" just seem to offer hope for some decent mainline hardware, full featured and decently priced, for the linux community.

Bruce,

Let me be very clear: Intel does not provide support for Linux on the NUC products. No, Intel is not backing away; Intel never has provided support for Linux on the NUC products and likely Intel never will provide support for Linux on the NUC products. No, you never saw the Supported Operating Systems page list any distribution of Linux as being supported. Yes, some helpful notes that have been posted, but this is all unsupported information from third parties.

No, this is not crazy; it is a simple economic decision. Each O/S release that is supported incurs a significant validation cost and a significant support cost. Each major version of each Linux distro would count as an O/S to be supported and would incur the same level of costs. Saying this another way, one major version of one Linux distro, say Ubuntu 17.10, would incur the same validation and support costs as would Windows 10 Home. The cost of validation and support must be sunk into the cost that Intel charges for a NUC. Are the 95% of users who use Windows 10 going to be willing to pay, say, $50 more for a NUC so that the various Linux distros that are used by the other 5% of users can be supported? Not a chance.

Now, before you attempt to argue with any of these numbers, I suggest that you spend some time reviewing the data in this article: https://en.wikipedia.org/wiki/Usage_share_of_operating_systems Usage share of operating systems - Wikipedia. As you will see, I have actually been generous in my estimate for Linux usage.

Practically any distro of Linux will run on the NUCs. In fact, NUCs are used by folks within Intel who work on the Linux kernel and on Linux device drivers. For Intel overall, Linux is important; very important -- but this doesn't mean that the NUCs, which must exist as separate, economically-viable products, can afford to include Linux support.

Scott -

I appreciate your candor and viewpoint in this issue and I agree. I wouldn't argue with the "numbers" at all.

Unfortunately, I do feel that there is a need for an operating system, such as Linux in the market. Every so often I review what is available as an alternative and then usually determine that, once again, Windows seems to be it.

The intended application and usage for the NUC platform is a stable isolated system. Windows cost, continual updates and larger space requirements made Linux seem attractive. You just can't turn off notifications and other irritants well enough on Windows 10. But Linux is a very fractured environment and I would be hard pressed to develop a working platform aside from a few systems or systems specifically designed and validated for a Linux distribution.

Frankly, I was just very impressed with the NUC platform. Thanks for all the hard work on an excellent product.

Hey, I was explaining the logic behind the decision, not expressing any opinion regarding Linux. If you want opinions, let's go for it...

First of all, I actually happen to like Linux. I spent part of my career doing development on Linux. My comment directed at Martin is specifically with regards to the utter disaster that is the world of portable software development.

Windows 10 is an absolute disaster as far as I am concerned. It seems that every release takes away features that I actually found helped my efficiency. So much time is wasted re-learning how to be (as) efficient using the latest version. There are three things that are killing Windows, (1) Microsoft's desire to make money through its app store, (2) Microsoft's desire to have the same O/S support phones and (3) Microsoft's arrogance and utter disregard for its customer's input (read: only we know what a good GUI should look like).

The major problem I see is that Linux is not the panacea that is going to keep Microsoft (more) honest. First of all, 90% of the people choosing Linux for their personal PC are doing so for no other reason than it is free (most have been scared away from Windows XP (the other free O/S of choice) by all the security issues). Secondly, there are simply too many distributions and few that are supported by an organization that is commercially viable (let alone successful). Because no one in the personal PC marketplace is willing to pay for these distributions, almost all lag well behind the hardware - sometimes by as much as 6 months! Intel has engineers working their butts off to get drivers for new hardware ready almost as quickly as for Windows, only to see the distributions taking months and months to actually incorporate them. Why is this? The folks that need to do the work to incorporate these drivers into the distributions are mostly volunteers and thus have to concentrate on their *real* jobs so that they can feed themselves.

Ok, let the "but"s fly...

I just stumbled onto this thread because I just recently bought a NUCC7CJYH and was "kinda" thinking of installing Linux (Ubuntu) on one of the SSD's I bought for it (the other WILL get Windows 10/64-bit). So I was doing my due-diligence about a Linux install and landed here.

While I may still install Ubuntu on one of the SSD for this NUC on of these days, it won't be the first to install because I just finished going through all the BS "rigamarole" at the Ubuntu for NUC website and this is like applying for a Government Security Clearance! (and I'm ex-USAF, a Capt., combat pilot and instructor!) Hesus! A SSO account required, SSH's Keys required, blood type, bend over and spread rectal exam .... OK I'm being facetious and exaggerating, but this is the list I WON'T NEED to install Windows 7, 8.1 or 10 - just a USB CD/DVD Drive; and why Linux will always be a Nerds OS and a pain in the Colonoscopy to install. (from Ubuntu site):

Minimum requirements
  • An Ubuntu SSO account with an SSH key
  • An Intel NUC with BIOS updated to the latest version (http://www.intel.com/content/www/us/en/support/boards-and-kits/000005850.html update instructions)
  • 2 USB 2.0 or 3.0 flash drives (2GB minimum)
  • A monitor with an HDMI interface
  • A Mini HDMI to HDMI cable
  • A USB keyboard and a mouse
  • A monitor with VGA or HDMI interface
  • A VGA or HDMI cable
  • A network connection with Internet access
  • An Ubuntu Desktop 18.04.1 LTS image
  • An Ubuntu Core image

I don't know, maybe Linux Nerds want to keep this OS dark and mysterious and awful to install for the majority of computer users that are "tinker IT level", but you'd think after 30 years the Linux bunch would figure out that only 1% of the world that installs Linux is telling you something. It's not worth the trouble and time required to just figure out how the install the damn thing and then another couple months of working out all the bugs that don't work. A 1000 piece jig-saw puzzle is a piece of cake compared to Linux installs.

Now I think I'll relax and tinker with a General Electric T700-GE-401 Jet Turbine engine .... easier than Linux; then install Windows 10 on the NUC, while watching American Ninja, in 10 minutes.

Interesting. So is this going to run as a "Dual Boot" on start up or as a sort-of Linux Emulator within Windows (kind of like Boot Camp on Mac OSX running Windows within?

Windows 7 and 10 runs decidedly slower than "native" when running in Mac OSX Boot Camp. This NUC is no power-house i5 or i7, so I'm concerned about a slow running Linux on top of Windows. I also had some interest like the threads OP in running KODI within a pure native Ubuntu install. I already have KODI installed in a couple hacked D-Link Boxee Box'es which has Intel Quad-cores in them.

No idea how it will work. Dual boot? Not necessary if you can run BOTH concurrently.

All master tinkerers should love this, eh?

Ah ha, want me to be there guinea pig huh on this Linux overlay on Windows?

For the OP, my new (w/o and OS installed yet) see's my 30" Philips "2k" LED/LCD TV on HDMI 3 slot just fine. sure you selected the right input on the TV control?

Anyways, I Got a problem, I finally got my 8GB of Crucial DDR4 2400 RAM finally yesterday for my newly acquired NUC7CJYH1, installed a new SanDisk 500GB SSD and connected a LG USB2.0 external CD/DVD/Blueray drive we use with a couple Windows notebooks w/o internal optical drives.

When I inserted a MSFT OEM Windows 7 64-bit installation disk (I plan to use a Win 10 update disk to get me to Win 10) and booted the NUC I got an error on the screen "Image Authorization Fail. System can not (should be cannot) boot to this device due to Security Violation. Press enter key to continue".

What is this??? We've used this same drive on numerous HP and a Dell Notebooks to update to like 7 and 8.1, never seen this error. The NUC also won't recognize a "Ultimate Boot CD" rescue / repair disk (used often on various Windows 7, 8.1 and 10 notebook and desktops - no problemo booting to it).

Does the NUC not like ext USB 2.0 CD/DVD/Blueray drives? How the heck am I supposed to install an OS off a factory install DVD??

Thanks for any advice.

This might come a bit late to help you, but you probably just need to disable Secure Boot in the BIOS settings.

Hello, everyone!

 

 

ka-nuc: As Al Hill mentioned, your OS is not supported by the NUC. Please go to https://01.org/ https://01.org/ for you to get drivers for your OS if that does not fix this issue go to the Linux* community for support about this problem you are facing.

If you read my message I never asked for support, all I wanted is to know if anyone using Linux has the same problem. Or are we not allowed to ask anything Linux-related here?

Hi ka-nuc, I have the NUC7PJYH Linux/HDMI/Audio all works. Running Kodi on Debian Stretch with back-ported 4.15 kernel. Also installed Intel DMC firmware for GeminiLake.

My TV is a first gen smart 4k Samsung 55" and my nuc boots up at 3840x2160 @30 hz, I think my TV doesn't support 60 HZ? although it could be the HDMI cable...fullsize 6 ft hdmi to hdmi.

Maybe it's your tv's not supporting hdmi2 is the problem, try it with a friend who has a 4k tv.

Here's a review where of the NUC7CJH where they tested with LINUX. http://nucblog.net/2018/04/gemini-lake-nuc-nuc7cjyh-review/ nucblog.net/2018/04/gemini-lake-nuc-nuc7cjyh-review/

good luck

Even though Intel says they don't support Linux OS at least you can choose Linux OS in the BIOS! Thanks for that Intel.

edit: ultraHD works at 3840x2160 @60HZ

had to enable UHD color in TV display options!

I have it running with ubuntu 17.10 and it is fine.

Why don't you try it with a smaller resolution maybe 1280x1024 to see if this helps?

crypt1,

What's your TV model? Can you see NUC splash screen and BIOS (after pressing F2) when UHD Color is ON? I tried several Samsung 4K TVs (2017 and 2018 models) and when UHD Color is ON TVs show "No Signal" during POST and in BIOS.

Thanks,

Peter

Wrong point of view.

If it does not work on my linux developer machine, I do not install it on the windows machines of my customers.
