[...] I have tried loading different acpi_* kernel modules, = and > none of them work. On the Lenovo L470 here and fairly recent -CURRENT I can control brightness with sysctl(8) after loading acpi_video(4) module. Also, as of base r360025 brightness change events are visible via devd(8): > # sysctl hw.acpi.video.lcd0.brightness=3D85 > hw.acpi.video.lcd0.brightness: 60 -> 85 >=20 > $ cat /var/run/devd.pipe >=20 > !system=3DACPI subsystem=3DVideo type=3Dbrightness notify=3D85 Your report was against 11.1-RELEASE which is no longer supported. Could y= ou please update to contemporary, supported FreeBSD version and reconduct your tests? --=20 You are receiving this mail because: You are the assignee for the bug.=
