LinuxQuestions.org - Dual-monitor one screen stays asleep after wake from DPMS standby

I've got Arch 64-bit running Openbox on an AMD64 with ATI HD5770, set to go to standby with DPMS. Usually after resuming from standby or suspend one or the other of my monitors will remain off, requiring me to open a terminal and run

Code:

xset dpms force off

Its not a big deal but a little annoying. Is there a way I could set a script to run this command every time the system comes out of standby?

The contents of 10-monitor.conf in xorg.conf.d, where dpms is configured, are as follows:

Code:

Section "ServerLayout"

    Identifier "DualScreen"

    Screen 0 "Screen0"

    Screen 1 "Screen1" Relative "Screen0" 1680 0

    Option "Xinerama" "1"

    Option "BlankTime" "0"

    Option "StandbyTime" "10"

    Option "SuspendTime" "20"

    Option "OffTime" "0"

EndSection



Section "Monitor"

    Identifier "Monitor0"

    Option "DPMS"

EndSection



Section "Monitor"

    Identifier "Monitor1"

    Option "DPMS"

EndSection



Section "Screen"

    Identifier "Screen0"

    Device "Radeon0"

    Monitor "Monitor0"

    Option "Position" "0 0"

    DefaultDepth 24

    SubSection "Display"

        Depth 24

        Modes "1680x1080" "1440x900" "1280x1024" "1024x768" "800x600"

        FbBpp 32

    EndSubSection

EndSection



Section "Screen"

    Identifier "Screen1"

    Device "Radeon1"

    Monitor "Monitor1"

    Option "Position" "1680 0"

    DefaultDepth 24

    SubSection "Display"

        Depth 24

        FbBpp 32

        Modes "1280x1024" "1024x768" "800x600"

    EndSubSection

EndSection

Thanks in advance for any suggestions and advice!
