Description Edgar Salgado 2016-09-18 07:55:40 UTC
I FreeBSD 11.0-RC3, 
I can change screen brightness with sysctl:

root@bsd-esalgado:/usr/home/esalgado # sysctl hw.acpi.video.lcd0.brightness=60
hw.acpi.video.lcd0.brightness: 70 -> 60

When pushing screen brightness control buttons, nothing happens.

Using xev, I can see that no event is triggered when pushing those buttons:

KeyPress event, serial 36, synthetic NO, window 0x2000001,
    root 0xb6, subw 0x0, time 613282, (166,-15), root:(427,234),
    state 0x0, keycode 146 (keysym 0x0, NoSymbol), same_screen YES,
    XLookupString gives 0 bytes:
