Public bug reported: [ Impact ]
* Dell is shipping a new Gorgon Point platform with an AMD iGPU and NVIDIA dGPU. On X11, the system incorrectly selects the NVIDIA dGPU as the primary GPU instead of the AMD iGPU, leading to increased power consumption and blocking certification. * This is the same issue as described in [1], where systems with hybrid graphics configurations need to use Wayland to ensure proper GPU selection. * Adding this platform to prefer Wayland via the mechanism introduced in [1] resolves this bug. [ Test Plan ] * On a Dell Gorgon Point platform: - Without the update, verify the system exhibits the bug (X11 is used by default and NVIDIA dGPU is incorrectly selected as primary) - Install the update and reboot - Confirm Wayland is selected (`echo $XDG_SESSION_TYPE` returns `wayland`) - Verify the AMD iGPU is selected as the renderer with `glxinfo -B` (should show AMD in the OpenGL renderer string) * On other platforms: - Confirm that display server selection is unchanged after the update [ Where problems could occur ] * If the platform identification rule is too broad, it could incorrectly match other platforms and force them to use Wayland when they should use X11, potentially causing issues on systems where Wayland isn't well-supported. * However, the rule specifically targets the Gorgon Point platform by its hardware identifiers, so it should not affect existing platforms. The change is isolated to platform detection logic and does not modify core display server functionality.
