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.
