Blue Screen when AV-Receiver is powered on after LE (HDMI not ready yet at boot)

bylokk · June 7, 2016 at 5:57 PM

Hi,

I have an Intel NUC DN2820FYKH with LibreElec installed, connected via HDMI to an AV-Receiver from Onkyo.

Whenever I power on the NUC first and afterwards the AV-Receiver then I only get a blue screen, and not the actual UI.
I have to restart the NUC so that the UI will come up correctly.

Ok, so that means whenever the HDMI connection wasn't ready at boot, then Kodi/LibreElec doesn't initalize video output.

With OpenElec everything was OK.
With LibreElec 7.0.0 and 7.0.1 I have this problem.

Any suggestions ?

You will most likely have to dump the edid and and have it there for when it boots, this should be possible to do from within LibreELEC.

thank you for pointing me to this article, I'll have a look!

I think this issue must have been there with OE too ... LE just boots a lot faster...

Is this something that can be fixed in later builds? I just upgraded my working NUC5i3RYH OpenELEC build to LibreElEC 7.0.2, and get zero video output, so I can't even pull the EDID. I've since rolled it back to the OpenELEC beta

If you are able to boot up OE as the last device in the chain, then that might be pure luck and probably gone with the next version. Nearly the same wiki exists for openelec, because users already have had problems with it:
Configuring a Custom xorg.conf - OpenELEC

So either be sure the HTPC is the last device in the chain which is powered on, or dump the EDID if you want it different. I agree, it would be very comfortable to turn on the device like any other HDMI device....but it is as it is

If you have zero video output even if you turned on your NUC as last device, then there might be a dfferent reason. As many many others users using a NUC with LibreELEC as well and have zero problems. So please confirm you have a GUI if you turn on the NUC as last device in the chain.

Zero output. I already had to boot my NUC as the last device in the chain when I was on OpenELEC, but once I upgraded to LibreELEC, there was no GUI at ALL, regardless of it being on last or not

I'm not running anything special: NUC5i3RYH -> Onkyo TX-NR708 -> LG TV, with a fresh install of LibreELEC 7.0.2 on an internal HDD. I just did a fresh install of OpenELEC 6.0.3 and it's running fine (minus needing to be on last in the chain, but that just seems to be a general NUC issue, not an OS one)

Was there just an unnoticed bug along the way to LibreELEC? Because the latest OpenELEC beta build (6.95.3) seems to give me the same issue, but it was working at one point

Have you tried the obvious things....changing cables and so on.

probably try one of the milhouse builds from kodi forums

I would ssh in and rename guisettings.xml.

Code

cd .kodi/userdata


mv guisettings.xml guisettings.xml.bkup

and reboot.

I have very occasionally found that something in there is incompatible across versions.

It's definitely not any sort of cable issue, as I'm using the same cables from OpenELEC to LibreELEC. The only thing changing each time is the OS installed on the HDD

I tried the latest Millhouse build #0722, but it has the same issues, it boots but no GUI. But then if I throw in the update/target files for OpenELEC 6.0.3 over SMB, shut it down, and turn it back on and I get the OpenELEC GUI just fine after it "updates"

I did this, but it didn't seem to have any effect. Still no video, but I do see that it created a new version of guisettings.xml alongside my backup

Would I be able to pull the EDID from OpenELEC since it works there and somehow import it into LibreELEC?

Yes the edid will be the same whether you grab it via oe or le.
