hummm... cpufreqd doesn't use the userspace governor :) > (Of course, installing a daemon that will set one of > powersave or performance policy depending of AC presence > is a good idea, but if you enable ACPI, you should > be able to do that via acpid(8)). yes, and it is probably more efficient since cpufreqd polls the system state while acpid grabs events from /proc/acpi/events aloha -- mattia :wq! -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
