Screensaver now works just fine (same kernel, with or without mplayer running, 10 minutes or 2 hours), so I'm completely lost as to why it failed. I tried looking through the .gnome and .gnome2 files for a clue, but there's nothing particularly informative in them, so I'm wondering where the screensaver settings are kept, etc. I'd rather not search every file on my system (some 800GB worth - ick!). Google was not particularly informative on this subject, either, although I did find out how to make my own slideshow.... Mark
