The backlight script is largely a copy of themixer service which provides the same value for mixers, but this one isspecifically dependant on kld to allow DRM drivers a chance to attach.Note that it's off by default to avoid interference with DEs, anddocument the capability in backlight(8). Set backlight_enable=YES inrc.conf(5) to enable save/restore.Relnotes: maybeReviewed by: bapt, ivy, manu, ziaeeDifferential Revision: https://reviews.freebsd.org/D59296 List of files: /freebsd/libexec/rc/rc.d/backlight Wed, 02 Sep 2026 05:51:41 +0200 Kyle Evans <kevans@FreeBSD.org>
