I've been having trouble with the KDE screensaver being turned off, too, using the current unstable Debian. This is speculation, but I think I've managed to find a reliable way to trigger it:
* Start an SDL application. They seem to turn off the screensaver while they're running, and restore it on exit. * Start a second SDL application. This one will presumably remember the original state as being one where the screensaver is off. * End the first application. The screensaver is restored to being on. * End the second application. The screensaver is "restored" to being off. Though I can't seem to turn off DPMS this way. Maybe something's wrong in my guessing... Torbjörn Andersson
