[SOLVED] betterlockscreen systemd service is dead

i'm currently configuring a laptop to run a systemd service for betterlockscreen, and my service status is dead (therefore my lockscreen doesn't run when my laptop exit sleep).

Betterlockscreen run fine by hand, dunst is installed and up to date, i run bspwm

here is the error i get : 

❯ systemctl status betterlockscreen@mathieu.service                       
○ betterlockscreen@mathieu.service - Lock screen when going to sleep/suspend
     Loaded: loaded (/usr/lib/systemd/system/betterlockscreen@.service; enabled; preset: disabled)
     Active: inactive (dead)

sept. 20 10:22:30 radium systemd[1]: Started Lock screen when going to sleep/suspend.

And here is the service file, as provided by betterlockscreen maintainer :

[Unit]
Description=Lock screen when going to sleep/suspend
Before=sleep.target
Before=suspend.target

[Service]
User=%I
Type=simple
Environment=DISPLAY=:0
ExecStart=/usr/bin/betterlockscreen --lock
TimeoutSec=infinity
ExecStartPost=/usr/bin/sleep 1

[Install]
WantedBy=sleep.target
WantedBy=suspend.target

Any idea what could be the issue, and how to fix it ?

Re: [SOLVED] betterlockscreen systemd service is dead

Well is DISPLAY=:0 correct? From your working session what's echo $DISPLAY? If you start bspwm via some display manager chances are that reserves DISPLAY:0 for itself and your actual session is somewhere else.

If you are using startx/xinitrc, make sure your xinitrc template is setup correctly as mentioned in https://wiki.archlinux.org/title/Xinit#xinitrc

thanks, that was indeed an issue with the display manager!
