Completly disable DPMS. How?

I want to disable DPMS completly.
I've put Option "DPMS" "false" to xorg.conf
Now I run xset -q | grep DPMS just after boot and see that DPMS is disabled. OK. Then I try to play video and after some time screen blanks. xset -q | grep DPMS shows that DPMS is enabled. What can be the reason?
I've tried to disable DPMS control in laptop-mode and even to turn off laptop-mode daemon - useless.

Sorry for bad English, it's not my native language.

Thanks in advance!

You've disabled dpms, but that still leaves the screen saver. You disable that with "xset s off". There's probably an xorg.conf option too.

Re: Completly disable DPMS. How?

I've tryed

xset dpms 0 0 0
xset s off

and

xset -dpms
xset s off
xset s noblank

In both variants xset -q showed me that DMPS is disabled. But again after some time screen blanked and xset -q showed, that DPMS enabled. So, something enables it back. Have no idea, what can it be :(

Check screensaver and power options as provided by your DE. Maybe something is set there.

No, screensaver and display power management in DE are disabled

Re: Completly disable DPMS. How?

I'm using KDE and looking for these options in System Settings -> Display and Monitor -> Screen Saver and System Settings -> Power Management -> Power Profiles. May be there are some other places, which are unknown for me?
