--- Comment #2 from Johannes P (johannes.pens...@gmail.com) --- Calling the brightness EC query method directly through the kernel ACPI debugger does not result in a change in value for the aforementioned register at B9. It appears to be dependent on a key press. Maybe it's also worth mentioning that when calling _Q11/_Q12, my trace wasn't able to pick up anything from GFX0.DD1F. - debug \_SB.PC00.LPCB.EC0._Q12 Evaluating \_SB.PC00.LPCB.EC0._Q12 AML Opcode: 0070 Store % ArgObj: 000000000dee6495 <Node> Name P80B RegionField 0000000052e7b4ee ArgObj: 000000008674c39a <Obj> Integer 0000000000000012 ResultObj: 000000008674c39a <Obj> Integer 0000000000000012 AML Opcode: 0086 Notify % ArgObj: 0000000073452c4b <Obj> Integer 0000000000000086 ArgObj: 00000000f420e657 <Node> Name DD1F Device AML Opcode: 0086 Notify % ArgObj: 0000000073452c4b <Obj> Integer 0000000000000080 ArgObj: 0000000072854c9d <Node> Name VPC0 Device Evaluation of \_SB.PC00.LPCB.EC0._Q12 returned object 000000001a14f500, external buffer length 18 [Integer] = 0000000000000012 [ 1731.602892] extrace-0138 ex_trace_point : Method Begin [0x00000000bd1e9420:\_SB.PC00.LPCB.EC0.VPC0.VPCW] execution.
