You could try to kldload acpi_video. # kldload acpi_video # sysctl -a | grep brightness should show up a key which you can use to set the brightness. # sysctl hw.acpi.video.lcd0.brightness=100 For some vendors (e.g. Lenovo) there are custom modules with their own brightness setting keys: # kldload acpi_ibm # sysctl -a | grep brightness If none of this are working, you might want to try out ports/sysutils/acpi_call and directly calling an ACPI method to increase or set the brightness. This was btw the only way it is working for my Lenovo X121e and E330.
