Subject: [PATCH 5.10 31/38] ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU
Date: Fri, 25 Mar 2022 16:05:15 +0100 [thread overview]
Message-ID: <20220325150420.641367363@linuxfoundation.org> (raw)
In-Reply-To: <20220325150419.757836392@linuxfoundation.org>
From: Werner Sembach <wse@tuxedocomputers.com>
commit c844d22fe0c0b37dc809adbdde6ceb6462c43acf upstream.
Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working
native and video interface. However the default detection mechanism first
registers the video interface before unregistering it again and switching
to the native interface during boot. This results in a dangling SBIOS
request for backlight change for some reason, causing the backlight to
switch to ~2% once per boot on the first power cord connect or disconnect
event. Setting the native interface explicitly circumvents this buggy
behaviour by avoiding the unregistering process.
