Public bug reported:

Suspend is delayed by 30 seconds likely due to GNOME Shell's screen lock
inhibitor not being released properly when lock-delay is set to 0.

Steps to reproduce:

Use Ubuntu 25.04 with GNOME Shell 48, login and start an application
like browser (the issue doesn't reproduce if you attempt suspend
immediately after login).

Trigger suspend via UI or systemctl suspend.

Expected result:
Screen locks and system suspends within a couple of seconds.

Actual result:
System waits exactly 30 seconds before suspending.

gsettings set org.gnome.desktop.screensaver lock-delay 1

causes GNOME to release the inhibitor promptly, and suspend happens
quickly.

An alternative is disabling screen lock (both idle and suspend) in the
security settings in which case suspend also happens quickly.

Conclusion:
This suggests that GNOME Shell registers a delay inhibitor for locking the 
screen, but does not properly release it when lock-delay = 0. Instead, systemd 
has to wait the full 30-second timeout before suspending.
