I'm just trying out OpenBSD 5.7 on a Toshiba Satellite Pro C660D laptop. It seems to work almost perfect, but I'm not able to find any way to control screen brightness. The display just stays at some predefined level set during power on.
Hotkey controls (Fn+F6, Fn+F7) do not work. Command line controls do not work either. xbacklight says: No outputs have backlight property Is there anything I can do to get it working somehow? Thank you. wsconsctl output: keyboard.type=pc-xt keyboard.bell.pitch=400 keyboard.bell.period=100 keyboard.bell.volume=50 keyboard.bell.pitch.default=400 keyboard.bell.period.default=100
