You should see a list of items, many of which will be '0', even though they should not be. Things like 'fan_speed'. Setting dev.acpi_ibm.0.mute or dev.acpi_ibm.0.thiklight to '1' should work. I think the hotkeys should default to 2484. --=20 R. Kevin Oberman, Network Engineer E-mail: kob6558@gmail.com
