From 1c8fbc1f9bfb804ef2f0d4ee9397ab800e33f23a Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 31 Mar 2020 14:36:23 +0200 Subject: [PATCH] ACPI: video: Use native backlight on Acer Aspire 5783z The Acer Aspire 5783z shipped with Windows 7 and as such does not trigger our "win8 ready" heuristic for prefering the native backlight interface. Still ACPI backlight control doesn't work on this model, where as the native (intel_video) backlight interface does work. Add a quirk to force using native backlight control on this model.
