Thanks! So I guess if I run a startup script that copies that variable to a file and then read that file from my cron job, that should do it. I'll try it later and respond if it doesn't work. Sorry if this wasn't an appropriate question for this list, but I thought this was the way to lock the screensaver from the command line in KDE per this (admittedly Ubuntu) answer: http://askubuntu.com/questions/61339/what-is-the-screen-locking-mechanism-under-kde So, if there is a better way to lock/unlock the screen in KDE, let me know what it is. I use this to unlock: qdbus | perl -ne 'qx/kquitapp $1/ if /(kscreenlocker_greet-\d+)/' Thanks again, David
