Bug Description

gnome-shell crashes instead of displaying a login screen:

gnome-shell[1954]: Running GNOME Shell (using mutter 45.3) as a Wayland display server
gnome-shell[1954]: Settings schema 'org.gnome.mutter.x11' is not installed

It seems the cause is a package version mismatch in mutter-common:

ii gir1.2-mutter-13:amd64 45.3-1ubuntu1 amd64 GObject introspection data for Mutter
ii libmutter-13-0:amd64 45.3-1ubuntu1 amd64 window manager library from the Mutter window manager
ii libmutter-13-dev:amd64 45.3-1ubuntu1 amd64 Development files for the Mutter window manager
ii libmutter-test-13 45.3-1ubuntu1 amd64 Test helper library for GNOME's window manager library
ii mutter 45.3-1ubuntu1 amd64 Example window manager using GNOME's window manager library
ii mutter-13-tests 45.3-1ubuntu1 amd64 Tests for GNOME's window manager library
ii mutter-common 46.0-1ubuntu6 all shared files for the Mutter window manager
ii mutter-common-bin 45.3-1ubuntu1 amd64 shared programs for the Mutter window manager

Downgrading mutter-common to https://launchpad.net/ubuntu/+source/mutter/45.3-1ubuntu1/+build/27621415/+files/mutter-common_45.3-1ubuntu1_all.deb appears to fix it.

Rather than treating this as a temporary issue I think we should fix the dependencies that led to it.

Seems the only reference to org.gnome.mutter.x11 is in x11-Add-support-for-fractional-scaling-using-Randr.patch

This caused it:

https://salsa.debian.org/gnome-team/mutter/-/commit/414010ddef06757000175c30238371739199d29a

meaning org.gnome.mutter.x11.gschema.xml is no longer installed with 46 along with X11 fractional scaling support.

This bug was fixed in the package mutter - 46.0-1ubuntu7

---------------
mutter (46.0-1ubuntu7) noble; urgency=medium

  [ Daniel van Vugt ]
  * debian/control: mutter-common now breaks libmutter back to focal.
    Because we have dropped X11 fractional scaling support for now,
    `org.gnome.mutter.x11.gschema.xml` is no longer shipped and those
    older versions of libmutter will fail to start(LP: #2060423)
  * Add compositor-sync-ring-Allow-the-gpu_fence-to-be-moved.patch
    to fix lag and freezes on the Nvidia Xorg driver (LP: #2059847)
