screen blanking

[Simon]

Ive installed fedora core 2 onto my gateway solo 2500 laptop. Every 10 
minutes, or around 10 minutes the screen blanks, although doesnt appear 
to power down. Im running xfce but I cant seem to find any program which 
would let me disable this screen blanking. The screen needs to be able 
to stay on even when the system is idle. How can I disable this?

hey me too, but since it did not turn off any processes nor my wireless 
network, I didn't seem to mind, but if you get an answer let me know and 
thanks

Presuming that this is your screensaver, run:

xscreensaver-demo

in a terminal, which will bring up the dialog so that you can adjust the
screensaver properties or turn it off if you wish.

More than likely, you have it set to simply blank the screen every 10
minutes, without locking and requiring a password login.

I am also running XFCE4 under FC2. Keep in mind that XFCE4 does not have
specific apps for a lot of the system management functions. Since it is
gtk based however, you can use the GNOME apps, either from a terminal,
set up a launcher on the main panel or edit the desktop menu file
(~.xfce4/menu.xml) for them as needed.

HTH,

Check /etc/X11/xorg.conf for "DPMS"-Option in Monitor-Section. Make use 
of options "BlankTime", "SuspendTime", "StandbyTime" and "OffTime" to 
optimize this behavior.
Check Man-Pages for more detailed informations:

#> man xorg.conf

Yes also check the BIOS power saving settings and options.

Be consistent with the various power management options.  Things
like Advanced Power Management (APM), Advanced Configuration and Power
Interface (ACPI) and Display Power Management System (DPMS).

It is possibly silly to set ACPI on in the BIOS and then have 
a grub boot line that has flags like acpi=off or noapic.

ACPI is the new thing and way cool when it works.
   (this is what most laptops are just now getting right and
    is the service that triggers when the lid is closed or
    adjusts screen brightness, etc... ).

APM is the classic service.

DPMS is the display specific part and if I understand it can avail itself
  of one of the two above BIOS services or use other tricks.

In xorg.conf look for the monitor section and the dpms option.

Section "Monitor"
        Identifier   "Monitor0"
        ....
        Option      "dpms"
    EndSection

Im running a headless installed of fedora core 2 with no X interface 
installed, yet my screen still blanks itself after 10 minutes. As far as 
I can tell, this type of behaviour is disable in bios, and didnt occur 
when I was running win2k server on the same machine.

You're experiencing a console screen blank.  To disable it:

setterm -blank 0

Does this just apply to my current session? Going back to the login 
prompt my display still blanks after 10 minutes or so. Is there 
somewhere i can set no blanking as the default behaviour?

You could put the setterm command in /etc/bashrc or /etc/profile
(or in a .sh script in /etc/profile.d).  That would make it effective
for all logins, but not (likely) at the login prompt.  Putting a
setterm in rc.local might do what you want.
   The surest way is to disable this feature in the kernel.  That
seems to be the most commonly suggested option, as in this message:
