This bug was fixed in the package mutter - 46.2-1ubuntu0.24.04.1
---------------
mutter (46.2-1ubuntu0.24.04.1) noble; urgency=medium
[ Daniel van Vugt ]
* New upstream release 46.2 (LP: #2068598)
- Fixed mouse clicks falling through to the window behind (LP: #2026194)
- Fixed a crash in meta_wayland_transaction_commit (LP: #2061739)
- Fixed night light getting stuck on (LP: #2066902)
* New upstream release 46.1 (LP: #2064735):
- Fixed blank screen on hybrid GPU machines using nouveau (LP: #2066931)
- Fixed a monitor hotplug crash (LP: #2050865)
- Improved performance on secondary GPU monitors (LP: #2038801)
* Refreshed patches:
- Support-Dynamic-triple-double-buffering.patch (LP: #2070437, LP: #2070438)
- meson-Do-not-mark-CI-test-tools-as-required.patch
- Mark-several-additional-tests-as-flaky.patch
* Add clutter/conform gesture tests to the list of known flaky ones:
it's a new test in Mutter 46 and not yet reliable.
* Add build-Compile-schemas-locally-for-use-in-build-tests.patch to compile
gsettings schemas for use in build tests. Debian CI requires this now and
it makes rebuilds more resilient against infrastructure changes.
* Add wayland-Disable-linux-drm-syncobj-v1.patch to avoid enabling major
new features in Noble updates, as detailed in:
https://lists.ubuntu.com/archives/ubuntu-release/2024-May/006087.html
* Add backends-Handle-null-views-instead-of-creating-dummy-view.patch
to prevent "clutter_frame_clock_notify_presented: code should not be
reached" log spam in some Nvidia Wayland sessions (LP: #1967707)
* Add backends-Restore-support-for-X11-cursor-themes.patch to restore
support for X11 cursor themes, which was lost in Mutter 46.0
(LP: #2062377, LP: #2063869)
[ Jeremy Bícha ]
* Stop compiling gsettings schemas in debian/rules
* Opt into Salsa CI
* Drop packaging references to Hurd since this is Linux-only
* Update libmutter-14-0.symbols
* Update Breaks
* Refreshed patches:
- window-Add-ability-to-override-the-edge-constraints.patch
- x11-Add-support-for-fractional-scaling-using-Randr.patch
* Drop upstreamed patches:
- Nvidia-secondary-GPU-copy-acceleration.patch
- compositor-sync-ring-Allow-the-gpu_fence-to-be-moved.patch
[ Marco Trevisan ]
* Add place-Always-center-initial-setup.patch (LP: #2016013)

Primary GPU displays nothing if the secondary GPU is using nouveau in

Bug description:
[ Impact ]
Wayland sessions log in to a black screen, if a secondary GPU exists
that's using the nouveau driver and has a secondary monitor plugged
into it.
[ Test Plan ]
0. Find a machine with hybrid graphics: Intel integrated, Nvidia discrete.
1. Plug a second monitor into one of the ports wired to the discrete GPU.
2. Stick to the default nouveau graphics driver for Nvidia. No proprietary
drivers.
3. Reboot.
Verify the login screen appears and you can successfully log into a
Wayland session.
[ Where problems could occur ]
Although the bug affects dual GPU multi-monitor systems, what is
failing here is the primary monitor on the primary GPU. So the
potential risk is that the primary display starts failing on more
types of machines in Wayland sessions.
[ Original description ]
after upgrade from mantic to noble, my laptop booted to the firmware
splash screen with Ubuntu logo, plus a mouse cursor. The gdm login
screen did not appear.
Switching to disable wayland (as in the attached modified config file)
fixed this so that the login screen appears.
