mutter (46.2-1ubuntu0.24.04.9) noble; urgency=medium
[ Chun-Yi Wu ]
* Backport patches to fix AMD platform Nvidia dGPU screen freeze in
Wayland. It was seen as a screen freeze but actually just running on
the dGPU when that's not wired to the laptop display. (LP: #2111902)
[ Yao Wei (魏銘廷) ]
* d/p/wayland-Pass-latest-cogl-sync_fd-on-kms-update.patch:
Fix issue where glxgears runs slower than display refresh rate
(LP: #2111698)
[ Daniel van Vugt ]
* Add onscreen-native-Return-the-correct-number-of-EGL-modifier.patch
to fix multi-monitor reverse PRIME support on desktops where Nvidia is
primary and an integrated GPU is secondary. (LP: #1978905)

Bug description:
[ Impact ]
* On noble, AMD platform with Nvidia dGPU. The Nvidia dGPU is by
default selected as the primary GPU instead of the AMD iGPU.
In this case, screen freeze when login to the Wayland session.
[ Test Plan ]
* On AMD (StrixPoint or KrakanPoint) platform with Nvidia dGPU
* Select and login to the Wayland session. Can boot to desktop and
and move mouse around.
* Make sure XDG_SESSION_TYPE=wayland
* Use command 'glxinfo -B' and see AMD iGPU is selected as the
renderer means pass
* Regression test: Verify a single-GPU system can still boot to a
working desktop.
[ Where problems could occur ]
* Since the patch adjust the primary GPU selection heuristic, when
it goes wrong it might affect all systems using GNOME in Wayland.
For example, if a non-GPU device or other AMD GPU (if any) instead
of the correct one is misselected as the renderer
