Black screen after boot on recent RK3399 nightly builds (Rock 4 SE)

    Hi,

    I'm testing LibreELEC 13 nightly on a Radxa Rock 4 SE (RK3399) and I've found an issue with several recent nightly builds.

    I've tested the following images:

    • LibreELEC-RK3399.aarch64-13.0-nightly-20260303-505422f-rock-4se.img.gz → Works correctly
    • LibreELEC-RK3399.aarch64-13.0-nightly-20260722-05770be-rock-4se.img.gz → Black screen
    • LibreELEC-RK3399.aarch64-13.0-nightly-20260801-6dab8be-rock-4se.img.gz → Black screen
    • LibreELEC-RK3399.aarch64-13.0-nightly-20260804-b26c667-rock-4se.img.gz → Black screen
    • LibreELEC-RK3399.aarch64-13.0-nightly-20260805-ea720d5-rock-4se.img.gz → Black screen

    With all the builds that fail, the behavior is always the same:

    • The initial kernel boot messages are displayed.
    • After that, the screen goes completely black (the display remains active; it does not show a "No Signal" message).
    • Pressing the keyboard arrow keys produces Kodi navigation sounds, so the system appears to continue running.
    • Since these are clean installations, networking and SSH have not been configured yet, so I'm currently unable to collect logs from the failing builds.

    Is this a known issue?

    If there's any specific test you'd like me to perform or any logs you'd like me to collect, I'd be happy to do so by first booting a working build and following your instructions.

    Thanks!

    The kernel patches for older RK images are known broken for a while. I started to rework things but keep getting waylaid by other tasks; I also lack older RK hardware so it needs a load of guesswork. Right now I’m on vacation so there’s unlikely to be any change until later in the month.

    Thanks for the explanation.
    I appreciate the update.
    If you need someone to test future builds on RK3399 hardware, I'd be happy to help.

    Thanks! However, I can't find the 20260506-107b9f2 build for the Rock 4 SE.

    The closest ones available are:

    • 20260505-2501262

    Did you mean one of these?
