KDE - screen power off stops orking after a while

I have slackware 10.2 on a DELL C600 Laptop,, I have told KDE
in the control panel to turn off the screen after 1 minute of inactivity.
This works fine.
Unfortunately, after a while, it simply stops going on Power Off, ad if I were
still moving the mouse or something...

If I switch into RL3 then back into KDE, then it starts working again, it's very strange.

Also - when i go into StandBy from KLaptop, the screen stays on; is there a way
to avoid this?

Any help would be appreciated,

For the first problem, maybe you are still moving the mouse. What I mean is that it's not unusual for mice and touchpads to pick up on vibration or for the mouse to move slightly from cable pressure or to settle in a new position on an uneven surface, or for touchpad layers to settle some time after you stop using them.

To check for this you could dump the output of /dev/mouse into a text file before leaving the machine. If it wakes up when you're not using, return and check the contents of /dev/mouse for a non zero value.
cat /dev/mouse > /home/user/mousetest

There may be a movement threshold setting that you can increase.
