In my case, xev shows nothing. X does not know when the keys are pressed. The only response I get when I press the Fn keys are these acpi events registered in system log. > > Fedora 8 recognized my laptop volume controls without having to do > this. :) Unfortunately, this was not the case here :( However, at least now something shows up in the logs, that's a progress. With F7, nothing happens at all when the Fn keys are pressed at this laptop. []'s Marcelo
