Verified on the machine which has AMD iGPU + NVIDIA dGPU (headless) with the same OS version (noble) where the issue was originally tested.
Steps: (reproduce) 1. ssh login to the machine apt-cache policy check libmutter-14-0 version is '46.2-1ubuntu0.24.04.8' 2. set 'WaylandEnable=true' in /etc/gdm3/custom.conf and reboot the machine 3. login to the wayland session check screen freeze (verification) 4. apt install -t noble-proposed libmutter-14-0 and reboot machine 5. login to the wayland session see desktop screen, can move the mouse around, open the terminal and type 6. echo $XDG_SESSION_TYPE sees 'wayland' 7. apt-cache policy check libmutter-14-0 version is '46.2-1ubuntu0.24.04.9' 8. install mesa-utils and glxinfo -B check render is AMD iGPU Results: After upgrade to the proposed mutter package '46.2-1ubuntu0.24.04.9', can successfully login to the desktop screen under the wayland session and check the renderer is the AMD iGPU.
