Sway: Unlocking physlock after lid is closed (suspend/sleep) causes blank screen #112
Description
#96 is similar to my issue, but in my case I am using Sway, not LightDM.
swayidle is used to trigger the lock before suspend like so:
swayidle -w \
timeout 60 'physlock -dsm -p "1"' \
timeout 300 'swaymsg "output * dpms off"' resume 'swaymsg "output * dpms on"' \
before-sleep 'physlock -dsm -p "2"'When the lid is closed, suspend is triggered according to /etc/systemd/logind.conf which defines:
[Login]
...
HandleLidSwitch=suspend
...When closing the lid, suspend is indeed triggered, and when waking form suspend, physlock shows a password prompt. But when the correct password is entered, the screen switches to a blank black screen. The only way to fix this is to switch to a different TTY, login, and kill Sway.
Just to clarify, the blank screen does not occur when using physlock during "regular" usage, i.e. without sleep/suspend triggers.
If I manually lock, then close the lid and suspend, the blank screen doesn't happen. But in that case, when I wake from suspend, then unlock, then proceed to lock again, this is the output:
physlock -d -s -m
physlock: /dev/tty-1: No such file or directory
And ps aux | grep physlock returns a list of ~60 physlock processes for the root user.
