Please only use the LibreELEC Hyperion addon and the LibreELEC Hypercon version to configure it (see this Wiki page for details Hypercon [LibreELEC.wiki]).

Alright, tried again with 9.2.0. There the installation from the repository works. And with the LE version so does the drop-in. So far it boots without crashing. Thank you for your help!

Run systemctl status service.hyperion and check if it has correctly picked up the delay.conf drop-in. You should see the systemd service loaded from the kodi addon-folder and the Drop-In loaded from the systemd config folder

Code

Unit service.hyperion.service could not be found.

I installed it via HyperCon. I tried to install it from the libreelec repository but the installation fails. I guess this at least explains why the delay won't happen.

I've just watched Disenchantment S02E01 from netflix at 1080p24 with hyperion active on a RPi4 4GB and didn't notice and screen dropouts or other issues. So not quite sure what might be going wrong on your setup.

A rather common cause for screen blackouts, especially with CPU demanding content like software decoded video or power demanding peripherals like USB HDDs or DVD drives are marginal power supplies - if you're not using the official RPi power supply (I use that here and it's fine) or if you have one or more bus-powered USB HDDs you might look into that.

So far I'm only aware (and can reproduce) 2 major issues with Hyperion (more specifically the dispmanx grabber):

4k playback with the dispmanx grabber / Hyperion active results in no signal on the HDMI output. There's currently no workaround or solution available, reason for that seems to be that the RAM bandwidth is just too high. This is a known issue and it will be fixed eventually (but seems to be a bit low priority - it needs to be fixed in the RPi firmware so not much we can do about it).

The other issue I frequently see here is no HDMI signal at all after a cold boot (on my 4kp60 screen) if Hyperion is active. A simple workaround for that is to start Hyperion after Kodi has started, I'm using a simple systemd drop-in here to do that:

.config/system.d/service.hyperion.service.d/delay.conf

Code

[Unit]
After=kodi.service

[Service]
ExecStartPre=/usr/bin/sleep 10

Not exactly sure what causes the no-signal issue (could be something in the firmware), but with the drop-in workaround everything's been fine here in the last weeks.

Beginning with 9.1.502 my HDMI signal crashes on a cold boot as well. So I wanted to try your workaround to delay Hyperion.

Unfortunately the delay doesn't work.

The start up rainbow swirl of Hyperion happens right on the LibreElec bootscreen no matter how much time I put in the config file.

Do you have any idea why that might be? I put your code into a file "delay.conf" in a new folder "service.hyperion.service.d" into the "system.d"-folder. Thanks for your help!

For the time being I have to stick to 9.1.501 where it never crashes on boot.
