Bug#961146: systemd-logind sometimes ignores a systemd-inhibit lock

[Vincent Lefevre]

Package: systemd
Version: 245.5-2
Severity: normal

I use a systemd-inhibit lock, which has currently been running
since 19:12, as shown by:

zira:~,2> ps -fwwC systemd-inhibit
UID          PID    PPID  C STIME TTY          TIME CMD
vinc17     34134       1  0 19:12 ?        00:00:00 systemd-inhibit --what=handle-lid-switch --who=vinc17 --why=power supply or external output --mode=block /home/vinc17/wd/src/scripts/inhibit-suspend 10 log +

zira:~,2> systemd-inhibit --list --no-pager
WHO    UID  USER   PID   COMM            WHAT              WHY                             MODE 
vinc17 1000 vinc17 34134 systemd-inhibit handle-lid-switch power supply or external output block

1 inhibitors listed.

But when I closed the lid at 20:55, the system got suspended:

[...]
May 20 20:55:08 zira inhibit-suspend[48475]: (vinc17) on-line: yes
May 20 20:55:08 zira inhibit-suspend[48480]: (vinc17) output: 0
May 20 20:55:14 zira systemd-logind[785]: Lid closed.
May 20 20:55:14 zira systemd-logind[785]: Suspending...
[...]

I don't know what changed now for systemd, but I've exceptionally
started the X server from a VT.
