Hi,

I am running Debian 10 and sometimes idle is not detected correctly on my 
(KDE) system and the desktop is not going to suspend.

A typical candidate is a not correctly terminating vlc process which does not 
have a screen anymore but is still alive. Sometimes I cannot find out what 
causes the problem.

Is there a way to find out what is the holding back the idle detection?

I am thinking of something like doing a dry-run of the idle detection by cron 
with a report every few minutes and log the report (without actually 
triggering suspend if idle is detected). Whenever idle is not detected 
properly, the log file would tell the reason.

Any idea or hint is welcome.

Many thanks
Rainer
