Look in the file /etc/rc.d/rc.M , I think its line #25 that reads:

Code:

/bin/setterm -blank 15 -powersave powerdown -powerdown 60

Change it to something like:

Code:

/bin/setterm -blank 0 -powersave off -powerdown 0

Of course, for more info read:

Code:

man setterm

thanks for the info, wadsworth.

To prevent the screen from shutting itself off while using X, add:

Code:

Option "DPMS"  "0"

To the Monitor section:

Section "Monitor"

However, normally (if set to 1) it does save power when you leave the computer if you forget to turn the monitor off. It's your choice.

EDIT:
So in your case it would be:

Code:

Section "Monitor"
    Identifier     "My Monitor"
    HorizSync       31.5 - 50.0
    VertRefresh     40.0 - 90.0
    Option "DPMS"  "0"
EndSection

thanks H_TeXMeX_H.my monitor stop blanking now after i followed your instructions.thanks, guys.

You can also run "xset -dpms" to turn it off manually, and "xset +dpms" to turn it back on, and place it in one of your startup scripts, instead of modifying xorg.conf.

xset can also be used to fine-tune the dpms settings, changing the amount of time required before they activate, for example. Check the man page if you're interested.

FYI, dpms is the monitor's "Energy Star" power saving feature. It's built into the monitor, but controlled by the video driver.

If you do not like modifying the original rc.d scripts, then copy the text from rc.M to rc.local. In rc.local modify the setterm parameters. The rc.local script is run last and the new command will override the one in rc.M.
