Hi, thanks for your bug report. Depending on your specific MacBook model, there could be a directory in /sys/devices/virtual/backlight/ , for example called apple_backlight. If so, you can try to write to the file 'brightness' in there and see if your backlight changes, like this: $ echo 8 | sudo tee /sys/devices/virtual/backlight/apple_backlight/brightness if your backlight changes, the mechanism to change it works but the keys don't. If not, then it's more a driver/hardware issue.
