https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D207086 --- Comment #6 from commit-hook@freebsd.org --- A commit references this bug: Author: avg Date: Tue May 5 12:14:12 UTC 2020 New revision: 360657 URL: https://svnweb.freebsd.org/changeset/base/360657 Log: acpi_video: try our best to work on systems without non-essential methods Only _BCL and _BCM methods seem to be essential to the driver's operation. If _BQC is missing then we can assume that the current brightness is whatever we set by the last _BCM invocation. If _DCS or _DGS is missing the we can make assumptions as well. The change is based on a patch suggested by Anthony Jenkins <Scoobi_doo@yahoo.com> in PR 207086.
