dmesg log

Well it still doesn't help, brightness levels won't change but this time I see somewhat more output from dmesg like:

[ 82.536612] exregion-0187 [4294967280] ex_system_memory_space: System-Memory (width 8) R/W 0 Address=000000007F6E1E8A
[ 82.536671] evmisc-0125 [4294967272] ev_queue_notify_reques: Dispatching Notify on [DD02] Node ffff88007f011ae0 Value 0x86 (**Device Specific**)
[ 82.536695] ACPI: Failed to switch the brightness

The last two weren't appearing untill now, I think you are getting very close...
