** Description changed: [ 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 + * Use command 'glxinfo -B' and see AMD iGPU is selected as the + renderer means pass + + * Regression test: Ensure single-GPU systems 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 [ Other Info ] * Upstream MP: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/4114
