I was going to suggest you check your dpms settings. This is what controls
screen blanking under X. But then I recalled that you run KDE, and I don't
know how it interacts with DPMS. Although I typically don't use it, I've
noticed intermittent results with Xscreensaver too.

I've also gotten intermittent results running programs that mess with
dpms. mplayer, for example disables dpms on startup, and re-enables it on
exit.

FWIW, man xset will get you the initial scoop on dpms.
