Kevin Oberman, Network Engineer > E-mail: rkoberman@gmail.com On my T520, I do not need acpi_ibm(4) for the thinklight to function. It works with/without the module loaded. Hiren and I found adding this to the driver section of xorg.conf allows the fn-brightness keys to work: Option "RegistryDwords" "EnableBrightnessControl=1" The audio "mute" button actually seems to be working through the sound driver. The fn key seems to generate an unhandled APIC0 event, that is processed somewhere as a shutdown event. I'm using XFCE4 as my desktop and all the parts that come with it. Sean
