Your weston.ini did not indicate otherwise, but if you happen to use any other shell plugin, it is up to that to implement the locking behaviour. Desktop-shell will only accept unlock requests from weston-desktop-shell, the helper client it launches at compositor start. In upstream, that helper client only implements a simple dialog with a green button that unlocks the desktop. It has no functionality to launch other programs or use them for unlocking, that is something you have to add yourself in the code. I don't know why the screen lock does not engage for you. I have a vague recollection of two different timeouts for blanking vs. locking, but I saw only one in the master branch at least. Thanks, pq
