Hi Christopher, Thanks for the bug report. Can you please provide run: grep '.*' /sys/class/dmi/id/*_* 2> /dev/null > dmi.log And then attach the generated dmi.log file here, then I can add a quirk to the kernel to automatically enable native_brightness on your model laptop. Regards. Hans dmi.log ends up with: /sys/class/dmi/id/bios_date:02/13/2015 /sys/class/dmi/id/bios_vendor:Apple Inc. /sys/class/dmi/id/bios_version:MBP121.88Z.0167.B00.1502132146 /sys/class/dmi/id/board_asset_tag: /sys/class/dmi/id/board_name:Mac-E43C1C25D4880AD6 /sys/class/dmi/id/board_vendor:Apple Inc. /sys/class/dmi/id/board_version:MacBookPro12,1 /sys/class/dmi/id/chassis_asset_tag: /sys/class/dmi/id/chassis_type:9 /sys/class/dmi/id/chassis_vendor:Apple Inc. /sys/class/dmi/id/chassis_version:Mac-E43C1C25D4880AD6 /sys/class/dmi/id/product_name:MacBookPro12,1 /sys/class/dmi/id/product_version:1.0 /sys/class/dmi/id/sys_vendor:Apple Inc.
