And there is no bios upgrade for my notebook :( I forgot to say two things: When I loaded the module, a new message appeared (booting with and without acpi_osi=Linux): sony-laptop: Sony Notebook Control Driver v0.6. input: Sony Vaio Keys as /class/input/input9 input: Sony Vaio Jogdial as /class/input/input10 --> [Firmware Bug]: ACPI: ACPI brightness control misses _BQC function sony-laptop: brightness ignored, must be controlled by ACPI video driver And these errors show in any ACPI events (lid open/close, press power button ...), not just in Fn-Keys. -- []'s Rodrigo Luiz -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
