Description Ángel Navarro 2025-12-28 05:03:51 UTC

Alright, I hit this bug EIGHT times today and it REALLY pissed me off. Hope you find the root cause and fix this, by the way. All cases were only fixed by a FORCED SHUTDOWN... 

While on a trip, I wanted to use my laptop to play music while the screen was turned off, so I gone to Battery > set both "When inactive" and "When laptop lid closed" to "Do Nothing", used Elisa to play music, locked the screen and pressed Esc to softly turn off the screen without suspending as always, and boom.

The music kept playing, but after a while, when I wanted to use my computer, turns out Plasma decided to stop rendering ABSOLUTELY anything. Black screen, no matter if I switched TTYs or press whatever button (including power), Plasma would not render anything to the screen even though I could change tracks with my Bluetooth's airbuds buttons.

Then the logs are flooded with:

STEPS TO REPRODUCE
1. Play music through Elisa
2. Set both "When inactive" and "When laptop lid closed" to "Do Nothing" (preferably on battery, but I also hit this TWICE while being on AC)
3. Lock the screen (Meta + L)
4. Press Esc and watch the render not come back to life

OBSERVED RESULT
Graphics frost in a black screen even though the system is still "technically working", and the logs flooded with framebuffer fails:

dic 27 10:48:51 malasdecisiones kwin_wayland[3379]: src QRectF(0,0 2560x1440) -> dst QRect(0,0 2560x1440)

dic 27 10:48:51 malasdecisiones kwin_wayland[3379]: Failed to find a working output layer configuration! Enabled layers:

EXPECTED RESULT
A simple innocent screen lock while playing music MUST NOT bring down the entire graphics pipeline 💀

Comment 2 David Edmundson 2025-12-28 12:00:04 UTC

Can you reproduce this everytime?

Comment 3 Ángel Navarro 2025-12-29 03:29:26 UTC

Unfortunately, yes. Just letting the first song so it's about to finish is enough to trigger this bug.

Actually, you can rule the "Elisa needs to be playing music part" as it can also be triggered after a cold boot while not playing audio and Elisa isn't opened yet.

Here are some videos where I reproduced it. Please listen to the voice over so you can get a closer reference on what's happening.

The invalid argument log lines were also in bug 500038

Looking at the logs, it looks like there are also a ton of systemd coredumps, for example:
