From: "Chia-Lin Kao (AceLan)" <acelan.kao@canonical.com> BugLink: https://launchpad.net/bugs/2008871 [Impact] Sometimes the system boots up with both acpi_video0 and amdgpu_bl0 sysfs interfaces and the acpi_video0 doesn't work. [Fix] Add this machine to the video_detect_dmi_table to force it uses native backlight interface which is amdgpu_bl0. https://lkml.org/lkml/2023/3/2/187 [Verify] Verified by our QA and ODM. [Where problems could occur] Pretty safe to add the DMI quirk, won't affect other platforms.
