NUC7i5BNH doesn't turn on monitor after wake up (linux)

niklavs Jun 19, 2017 1:36 PM

Hello !

My new NUC doesn't turn on monitor after OS went to sleep(Suspend).
NUC is turning on, and OS is waking up, but monitor stays off.

NUC model: NUC7i5BNH
Monitor: Envision G2460w
Cable: HDMI to DVI male-male cable with gold-plated connectors, 1.8m, bulk package (CC-HDMI-DVI-6)

OS: elementary OS 0.4.1 Loki / Built on "Ubuntu 16.04.2 LTS" / Linux 4.8.0-54-generic / installed in UEFI mode

BIOS: 0046

Was searching all over the internet, didn't found any solution :/
Any ideas ?

In Windows, the simple workaround for this issue is to disable Monitor Sleep. There should be something similar you can configure in Linux...

Hello N. Scott Pearson,

Thank you for contacting the Intel community.

If you try straight connection instead of HDMI to DVI do you get the same problem?

Is it possible for you to try straight connection?

Regards,

Ivan U.

i had to turn off monitor sleep now. as this happens not only in windows but also linux, so it means this problem is not caused by software.....

Hello WW6302,

Yes, that’s what I meant with straight connection.

If you are using Linux* we recommend you use the latest kernel. If you need assistance with Linux* on Intel NUC, check your distro's website and forums for peer assistance.

You can also try turning off the computer.
As you turn it back on tap the F2 key. This will load BIOS setup.
Press F9 to load defaults.
Press F10 to save and exit.

Please let me know.

Regards,

Ivan U.

In this case, let’s wait for niklavs to get the new cable and let’s see how it goes after that.

Meanwhile, would you please provide us with your system configuration, you can use the Intel SSU (System Support Utility) https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility:
Download Intel® System Support Utility

Download the utility

Run the exe and select ‘Scan’

Save and include as an attachment in the Intel Community Forum

Hello!
Got the HDMI to HDMI cable from Cablexpert.
And Suspending works now. So looks like the NUC doesn't know how to suspend the monitor on DVI port.

Anyway, thanks for support!

You are more than welcome and thank you for letting us know the result.

I’m glad that with the new cable the issue has been resolved and yes most likely the conversion from HDMI to DVI is not recognized by the system.

I hope you can have a better experience with your unit from now on.

Best wishes,

Ivan U.
