Description Vít Ondruch 2026-02-10 20:21:20 UTC 
On my new LP, when booting, only black screen is displayed instead of LUKS password prompt. After I enter my password, the usual boot screen appears and the boot continues. I have tried to remove the `rhgb`, but even in this scenario, the LUKS password screen was just black. Not sure how to debug further. Also not sure if there might be some relation to bug 2430613

$ rpm -q plymouth
plymouth-24.004.60-24.fc44.x86_64

$ rpm -q kernel
kernel-6.18.9-200.fc43.x86_64

Reproducible: Always

I have tried e.g. `sudo grubby --update-kernel=ALL --args="plymouth.use-simpledrm=0"` but without much success :/
