Am using Ubuntu Lucid + kubuntu-desktop. NVidia works fine. Screensavers set to autostart & worked fine after initial install. Now screensaver attempted to start (brief flash of black only) but since quit doing that.. All screensavers work fine in Test mode. Is there a file entry that controls this?. kde/autostart is empty - should there be an entry here? Would the log files show up any relative errors? I am a newbie & the log info is way out of my league! Have not found any relative posts here or other forums. I would appreciate suggestions.
