Some other daemon process acquired the the event interface before powersaved could. Identify the process with lsof |grep "/proc/acpi/event" In rare cases its known that users encounter races between services for the ACPI event interface. Only acpid should access the kernel interface directly; other user space processes should use the socket of acpid to collect ACPI events. Since you're using SL 10.0 I suspect you're packages are not up-to-date. As a fortuneteller: You've installed mobile selection of SUSE 10.0, thus IAL (iald) is running which acquires the ACPI event interface as fallback. On a Acer notebook its safe to drop iald. > I considered that it might be, that X is started before acpi.
