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
[ 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
