Hello, I am running FreeBSD 14.0 on a Lenovo Legion 5 17 CH6H with i3wm. The function keys for regulating brightness, Fn+F5 and Fn+F6 modify hw.acpi.video.lcd0.brightness 2 to 100, but in reality the brightness of the screen remains unchanged, and stay at maximum brightness. I tried backlight and xandr without result. Backlight doesn't create /dev/backlight.
