With ACPI the responsibility may be switched to OS, but the interface doesn't follow ACPI specification section B.7. I assume there is a proprietary interface to do it. Or proprietary initialization that turn on standard interface, at least. > maybe there is a problem between freebsd ACPI <-> the laptop screen Maybe. You got some notifications but not those related to brightness keys. I doesn't assume there is problem with receiving one type of ACPI notification while other can be received with no problem ... Dan
