[Solved] Screen blanks every 10 minutes

I moved the power management sliders to the "never" postion but no help.  Every 10 minutes, the screen goes blank.  My bios has no provision to blank the screen.  Never happened with Ubuntu which I ran for over 2 years.  I'm running xfce4 but can't find anything in it that blanks the screen.

This also happened during the install when I'd leave the screen for a few minutes.  Is this an internal Arch program?

I watch a lot of movies on Netflix so this is a real big pain in the body parts.
Help!
Burt

Maybe this might be an answer to the issue. This seemed to work for me, but I'm using Xmonad..

OK.  I'll give it a shot and post my results.

I read up a little on DPMS and added the Option Offtime 120 to my xorg.conf.  Maybe that'll fix things.

Thanks,
Burt

Heh, I was wondering myself and found the definition smile

Short for Display Power Management Signaling, a VESA interface standard that defines four power management modes for monitors in idle state: on, stand-by, suspend and off. Using DPMS, the display controller (typically the video card or chip from which the monitor receives signals) sends a signal along two signal lines – horizontal sync (h-sync) and vertical sync (v-sync) -- to the monitor, instructing it to enter into one of the four power management states.

Re: [Solved] Screen blanks every 10 minutes

I used to have the same problem until i added BlankTime "0" to the ServerLayout section of my xorg.conf so it looks like this

Section "ServerLayout"
            Identifier        "X.org Configured"
            Screen      0   "aticonfig-Screen[0]-0" 0 0
            InputDevice    "SynapticsTouchpad" "SendCoreEvents"
            InputDevice    "Keyboard0" "CoreKeyboard"
            Option            "BlankTime" "0"

Re: [Solved] Screen blanks every 10 minutes

guzz46,
The change to "Offtime" didn't work.  When I returned to the computer after about 30 minutes, the screen was blank.  I'm tring the BlankTime option.  Do I need to use the Identifier "X.org Configured?"  My default identifier is "Layout0."

Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0"
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
    Option         "BlankTime" "0"
    #Option        "Offtime"  "120"   # doesn't work
EndSection

    #Option        "Offtime"  "120"   # doesn't work
EndSection

I'm not sure if there is any difference between X.org configured and layout0 but where you have it at the moment should be good

This works.  Screen was on for a few hours with no blanking.
