trouble with screensaver not locking

Hello TDE users/developers: I am using debian/buster now since it's release.  I am also using the "preliminary stable builds" of TDE using the following location: deb http://mirror.ppa.trinitydesktop.org/trinity-sb buster deps-r14 main-r14 I still have a couple of problems remaining.  Perhaps I can get this one fixed first. I have set my screen to be blanked (it can be any of the options on configure - kdesktop).  It will not automatically blank or lock.  I can manually blank and lock it, and it works as expected.  Only the automatic method by waiting a set amount of time is not working. How can I diagnose and fix this problem.  I have used other screensavers, and this is the only one that is giving me problems, and this is the one I prefer (from within TDE). Thanks again.
