I usually leave my computer running throughout the night. When I come to it in the morning most of the time I cannot unlock on the first try. When I enter password, the lockscreen starts to unlock but it never finishes. I have to cancel unlocking (via [Esc]) and then to try again, which works perfectly and then I am in. This is what I have in the journalctl

Any ideas?
