Solution was to add hint.acpi_perf.0.disabled="1" to /boot/loader.conf But now I have the problem that a regular user can't change the brightness: akima:~>6: sysctl -w dev.acpi_sony.0.brightness=5 dev.acpi_sony.0.brightness: 7 sysctl: dev.acpi_sony.0.brightness: Operation not permitted Is there a tunable to allow regular users to write to dev. sysctls or even better, a sysctl MIB security mask to assign "rights" to a specific MIB?
