Bug Description

xfce4-screensaver started not enabling after the 'Saver Timeout' would be past. At some point I removed light-locker as per one of comments in https://bugs.launchpad.net/ubuntu/+source/xfce4-screensaver/+bug/1875025 as I have having password unlock issues.

To give some background - I did an upgrade from 16.04 to 18.xx and then to 20.04 LTS.

Ever since then I believe xfce4-screensaver hasn't behaved properly. My laptop will be idle and it sometimes works (xfce4-screensaver sometimes enables and sometimes not). I still cannot find when it works and when it doesn't. I sometimes have to shutdown xfce4-screensaver and restart it. When I do this and to try and debug this I have been running:

'xfce4-screensaver --no-daemon --debug 2>&1| tee xfce4-screensaver.debug'.

Attached is that file from the last couple of days.

My xfce4-screensaver options are:
SCREENSAVER tab:
- Enables Screensaver: ON
- Activate screensaver when computer is idle: ON
- Regard the computer as idle: 2min
- Inhibit screensaver for fullscreen applications: ON
LOCK SCREEN tab:
- Enable Lock Screen: OFF

If I kill -15 the xfce4-screensaver process and restart it, the screensaver will work ok but when I close lid and open again during future session, screensaver will not work but is still running..

I believe I can reproduce this on Xubuntu 22.10 kinetic. Basically my issue is that *sometimes* the screensaver will not lock the screen when the system is idle.

This is reproducible about 70% of the time. Sometimes it works.

I have a workaround:
1. Open screensaver settings (xfce4-screensaver-preferences)
2. Toggle 'Activate screensaver when computer is idle' and touch the option 'Regard the computer as idle after'. By 'toggle' I mean disable, then re-enable it. By 'touch' I mean, change to arbitrary value, then revert to desired value.

This should make the screensaver respect your settings, at least for the current session.

### Current configuration:
- Activate screensaver when computer is idle: ON
-- Regard the computer as idle after: 9 minutes
