Peek-a-bangs (Emo Bangs or Bangs Covering One Eye) Hairstyle Issue
Author: faoitephCreated Aug 25, 2026Updated Aug 25, 2026
When I'm enrolling my face with my emo bangs (bangs covering one eye) thru sudo howdy add, howdy will hang for a while:
Please look straight into the camera
then it will halt the program itself:
No face detected, aborting
The catch: The system works if I pinned my bangs. It's kinda QoL issue to pin my hair everytime I want to unlock my PC.
GDP logs when I'm trying to enroll my face:
