Here are the instructions to capture the ioctl calls emitted by Nickel:
  • Put the attached strace binary somewhere on your device.
  • While Nickel is running, launch strace with:
    Code:
    ./strace -t -y -o strace.log -p $(pidof nickel) -e trace=ioctl
  • Open the frontlight dialog and:
    • Set the brightness to 0 % and the warmth to 0 %.
    • Set the brightness to 50 %, and then to 100 %.
    • Set the warmth to 50 %.
    • Set the brightness to 50%.
    • Set the warmth to 100 %.
    • Set the brightness to 100 %.
  • Stop the strace process with ctrl-c and post the output of grep ntx_io strace.log here.

Percents don't need to be exact: you can interpret 0 %, 50 %, and 100 % as near to the beginning, middle, and end of the slider's range.
