Bug Description

I have monitor standby set to 3 minutes, with no screen saver. After a full reboot the screen will enter standby mode as expected but after putting the system to sleep and waking it up again the monitor never goes to standby.

If I run the KDE system settings app and leave it open to the Hardware/Power Management/Energy Saving Settings page it seems to honour the standby timings even after a sleep/wake up, without requiring any action on my part (ie I don't need to hit Apply).

Ubuntu 12.04
KDE 4.84
uname -a: Linux <host> 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
