xset -dpms

Make sure you have any power management stuff disabled
in your BIOS.

Unfortunately, there are many variables here....

Also check the kde setup. There is a "timer" in there which also kicks
in after a short time. Ie, it is not just the screensaver you have to
worry about but also kde.

What happens when you hit a key. Does it pop back up?

Yes, it does, a key press brings back the monitor. Dpms was disabled. In
bios no power management is mentioned.

Try
K->Configuration->KDE->LookNFeel->Screensaver
and see what the timeout there is.
Also check what it brings up (it may well be set for blank screen, to save
power on a laptop)

(NOte that path of menu items above is on Mandrake and it may be
different on Redhat. Anyway, you want to look into the KDE
configuration)

The backlight of your laptop may be failing. Take a look at your screen under a bright light when the black screen occurs. If you can still see the page you were on slightly before your screen turned black, this is most likely the problem. You will probably have to get it replaced.

Make sure your screen saver is not set to "BLANK" with a timeout of one minute. It is better to set it to "NONE" with no timeout. Ben Rogers
