RPi + LibreELEC RPI4 reboot = HDMI signal loss

    Hi everybody!
    First of all thanks to everyone involved in this project for this fantastic piece of software!

    i have but one problem that whenever i reboot my RPI4, the TV loses the HDMI signal (using the internal grabber and the RPI4-Kodi as source)
    what happens is LE shuts down and the RPI4 reboots. i can even see the LE splashscreen and the hyperion LED swirl but after that the signal just craps out.LE itself seems to boot up as it should as i can control kodi with kore and SSH into the machine but no matter what i do i cannot get the HDMI signal back (rebooting again also doesn't help). The only thing that gets the signal back is to disconnect the power, wait for ~20sec and plug the power back in.

    i have already asked this on the LE forums and apparently the workaround is to add a delay to the hyperion startup forcing it to wait until kodi is fully loaded and then initialize hyperion
    (see https://forum.libreelec.tv/thread/2...etflix-etc-with-pi4/?postID=130791#post130791 for details). However the guy who came up with this idea installed hyperion via the LE-app.

    Since this website recommends NOT using the LE-addon but instead install hyperion through PC via SSH Hypercon this is what i did. That however means that running "systemctl status service.hyperion" returns "Unit service.hyperion.service could not be found."

    Now, can anyone help me to get this delay working on my setup? I am hesitant to just install the LE addon over the existing installation as i don't want to break things now that they are working (well sort of..)

    Still new to this so any help would be much appreciated, thanks!
