Bug#1077075: mutter: Monitors not detected on Wayland after upgrade on Debian 13/testing

[Fabrice Quenneville]

Package: mutter-common
Version: 46.3.1-2
Severity: critical
Justification: breaks the whole system
X-Debbugs-Cc: fabquenneville at gmail.com

Dear Maintainer,

Today after the daily upgrades on Trixie/Testing I lost two of my monitors on Wayland (I get all 4 on xorg.).

* What led up to the situation?

Today's daily upgrades: https://pastebin.com/RqVX9Bib

* What exactly did you do (or not do) that was effective (or ineffective)?

Loading the previous kernel was ineffective.
Turning off extensions was ineffective.
Logging-in on Gnome on xorg shows all my monitors.

* What was the outcome of this action?

Two of my 4 monitors still dont show on wayland but do on xorg. They are not listed in the>

* What outcome did you expect instead?

I normally have 4 monitors, two per GPU.
