As you used the phrase "stopped working", I'm wondering whether you were ever able to get ACPI brightness control to work on a Haswell machine? It seems to be broken on my Lifebook E744 (BIOS version 1.19): pressing the brightness keys causes acpi_fujitsu_notify() to call GBLL, which always returns the same brightness level, even though it sets the highest bit in its return value (which denotes a brightness change). Also, calling set_lcd_level() with various values causes the value subsequently returned by GBLL to change, but the actual screen brightness is identical all the time. > For the brightness control it's understandable, as this was handled by a > ACPI device FUJ02B1, which is no longer available.

It looks like it is handled purely in hardware because I'm not getting any scan codes or ACPI events either on a Lifebook E744 and the hotkey works correctly. -- Best regards, Michał Kępień -- To unsubscribe from this list: send the line "unsubscribe platform-driver-x86" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
