Description Jiri Eischmann 2026-02-23 14:00:04 UTC
The graphics break when I try to type the LUKS password on my Intel-based Dell XPS 13 Plus (9320) using Fedora 44 (6.19.2). It doesn't seem to be the same bug as https://bugzilla.redhat.com/show_bug.cgi?id=2438442 because its workaround doesn't work here.

Interestingly, when I connect an external display via USB-C, the problem stops, the graphics are rock solid even after I unplug the display again. I once managed to type the password and boot to GNOME, but broken graphics and display blinking persisted, so it isn't limited to Plymouth.

I recorded a video of it: https://cloud.eischmann.cz/s/He2Qztn5JWCeppR

   

Reproducible: Always

Comment 1 Fedora Blocker Bugs Application 2026-02-23 14:24:25 UTC
Proposed as a Blocker for 44-beta by Fedora user eischmann using the blocker tracking app because:

 It makes the OS basically impossible to use.

Comment 2 Kamil Páral 2026-02-23 14:34:26 UTC
Jiri, please provide the output of `lspci -nn` and `rpm -q kernel mesa-dri-drivers`, thanks.

Comment 3 Kamil Páral 2026-02-23 17:47:12 UTC
Discussed during blocker review meeting on 2026-02-23 [1]:

agreed 2441941 - punt (delay decision) - so far this is only reported to affect one system. On a closer inspection, the similar-but-not-identical 2438442 which we previously accepted as a blocker has also only been reported to affect one model, so far. Blocking on bugs that affect only one laptop model is a bit of a high bar especially for Beta. we plan to issue a call for testing asking folks with Intel laptops to see if they hit either bug and then re-evaluate both bugs based on the responses

Comment 4 Justin M. Forbes 2026-02-23 20:44:17 UTC
Can you list the contents of your initramfs? Asking as a user reported similar issues on a recent 6.18.x kernel update and a few userspace files were missing from the initramfs. A rebuild of the initramfs fixed the issue for that user.

Comment 5 Jiri Eischmann 2026-02-25 09:57:53 UTC
I just regenerated initramfs and it didn't help.

Here are the versions of the kernel and mesa-dri-drivers:
kernel-6.19.2-300.fc44.x86_64
mesa-dri-drivers-25.3.5-2.fc44.x86_64
