Having a fingerprint reader that works on Linux out of the box is… a bit surreal. But there are two small things I can’t seem to do in software that would make it slightly better:
- Wake on touch (e.g., send KEY_WAKEUP). This would allow users to unlock with one touch instead of having to hit a random key first.
- Blink the power LED when waiting on a fingerprint (blink faster when the fingerprint is accepted?). There’s currently no feedback.
Of course, I don’t expect you’ll have much time to work on features like this for a while… but I figured I’d put it on your radar.
