Hello I've noticed that slock won't lock the screen if unclutter grabbed to mouse pointer. To be precise, the screen blacks for a short moment, and then returns to the desktop without password verification. This happens when
$ unclutter -grab was called more than 5 seconds before, or immediately when choosing non-default idle time $ unclutter -idle 0 -grab I've tested with slock 1.1 and 1.2. Upon researching this issue I found that it was already noticed by others. Arch wiki [1] blames unclutter for this and notes that is also breaks i3lock, which isn't confirmed in [2]. I'm not sure if you are fine with the current behaviour (by indeed blaming unclutter), or unaware of this issue.
