LCD brightness setting on NetBSD

If you have an operating ACPI subsystem, give this a try to set your screen brightness:

1. Check the actual value:

# sysctl -a | grep bright

2. Set the relevant sysctl parameter. Mine looks like this (default value is 100):

# sysctl -w hw.acpi.acpiout1.brightness=110
