           Summary: TV-out blinks every 30 seconds
           Product: kde
           Version: 4.6
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: dualhead
        AssignedTo: unassigned-bugs at kde.org

Version:           4.6 (using KDE 4.6.0) 
OS:                Linux

I noticed that TV-out keeps blinking every 30 seconds when using KDE.
Interesting points are that we need to reboot in order to stop TV blink. Even
logging off KDE killing all KDE process is not enough. TV keeps blinking even
when is not in use, just need to be connected through S-video.
This doesn't affect all KDE software but I could not pinpoint only one. 

The test I performed was to boot with latest kernel 2.6.37, KMS ATI driver, log
using KDM into fluxbox, connect S-Video to TV, use xrandr to turn TV out on. TV
keeps quite and usable. If I turn on konsole and krandrtray through terminal I
still have TV-out stable. When I turn on knotify4 it starts to blink every 30
secs. Killing all KDE process doesn't help. Killing XServer doesn't help
either. Only reboot fixes it.
However, if I delete knotify4 from my system and then reboot my Linux and log
into KDE my TV starts to blink. 

Reproducible: Always

Steps to Reproduce:
Login into KDE 4.6

Actual Results:  
TV through S-Video keeps blinking every 30 seconds

Expected Results:  
Stable TV-out

This was not present in version 4.5. 
This bug is some component that knotify4 and some other softwares but is not
present in konsole neither krandrtray.
