problem with the screen

Hello,
I have a problem with the screen saver with linux Debain 7.
I use a motherboard:
ASROCK Q1900B-ITX CARTE MERE

Here's what happens:

I did not need to have a cnc machine a screensaver.

This is a linux question really, but you are dead right, no place for a screensaver on a cnc controller.

You have not said what desktop environment you are running, that will have a bearing.
I seem to recall the distro uses the crappy xfce interface

In which case
www.google.co.uk/search?q=debian+wheezy+...DVV_mRNYjOmwHFiq-gDQ

ok thank you I will try tomorrow

After experimenting one week with various concepts of which none actually worked as expected I have found following options in XFCE desktop to disable the screensaver:

Application Menu -> Settings -> Power Manager -> General -> Monitor Power Management -> should be active
Application Menu -> Settings -> Power Manager -> General -> On AC -> Actions -> Put the computer to sleep when inactive -> scroll bar the to left -> Never
Application Menu -> Settings -> Power Manager -> General -> On AC -> Actions -> spin down hard disks -> not active
Application Menu -> Settings -> Power Manager -> General -> On AC -> Monitor -> Put display to sleep when computer is inactive for -> scroll bar to the left -> Never
Application Menu -> Settings -> Power Manager -> General -> On AC -> Monitor -> Switch off diplay when computer is inactive for -> scroll bar to the left -> Never
Application Menu -> Settings -> Power Manager -> General -> On AC -> Monitor -> Reduce Brightness when computer is inactive for -> scroll bar to the left -> Never

How to make autologin:
Open the file /etc/lightdm/lightdm.conf and navigate to line 78 (you can enable line numbers on Leafpad).
It should be saying #autologin-user=.
Remove the # and change it to have your username after (for example: autologin-user=test).
