Subject: [PATCH] ACPI: video: Use native backlight on Lenovo E41-25/45
Date: Mon, 16 Dec 2019 17:55:12 +0800 [thread overview]
Message-ID: <20191216095512.1782-1-aaron.ma@canonical.com> (raw)
ACPI backlight control doesn't work on 2 Lenovo E41 laptops.
So force to use native backlight control on them.
