Deactivate lock screen / screensaver

Hello,
on my Macbook Pro running openSuSE-11.2 (happy with it) I am annoyed by the
screen being locked after some 10 minutes of inactivity though I am watching
a movie.
In the kde settings the screen saver is switched of (even tried multi!).
The screen is locked, it is not power management shutting down the display.

Note that I use two screens, the external, bigger one shows the movie
(dragon player) whilst the internal one is indeed inactive. I would like
best to deactivate any locking / screen saving completely.

Did I miss another place where I ahve to switch something off ?

Thanks, arkascha

There have been some big problems with users and this.
KDE keeps moving the goal posts too. There is a plethora of settings for this and it may depend on your kde4 version.

Go thru every conceivable option.

This is an old option in the display section: ImageBam - Fast, Free Image Hosting and Photo Sharing
You probably don’t have it.

FYI: smplayer seems to work better at stopping this happening too.
