    Monitor stand by (apm?)

    When I installed RH7.1 on my Via/ATI Rage XL system I could go to KDE control centre and in the look&feel/screensaver I could set the time for the screen saver and the time to put the monitor to stand by.

    Now with RH7.2 on my AMD760/Rage Fury PRO and kernels ranging from stock to 2.4.17, the setting from KDE is gone to set the monitor to stand by.

    What do I need in the kernel (or anything else) to have the monitor to stand by again?

    Thank you for your time.

    hey otheos,
    in the file /etc/X11/XF86Config-4 file you need the line Option "dpms" in the moniter section, example is below.
    hth
    paul

    Code:
    Section "Monitor"
        Identifier  "Monitor0"
        VendorName  "Monitor Vendor"
        ModelName  "Monitor Model"
        HorizSync  30-69
        VertRefresh 50-160
        Gamma 1.5
        Option "dpms"
    EndSection

    Is it the same option for the old XF86?

    hey Kenshi,
    I don't know if the old xfree86 controlled the APM of the moniter at all, I kept a line xset +dpms /etc/X11/Xsetup_0

    Hey pbHarris, what about disableing that option, because my monitor goes black every 10 mins when im playing something with the joystick.

    Thanks,

    Option "dpms" is already there but no joy. Do I still need the apm modules?

    what about that xset command?

    And finally do you actually get the option in kde control centre?

    This is how I have power management setup in the kernel as suggested by pbharris.

    CONFIG_PM=y
    # CONFIG_ACPI is not set
    CONFIG_APM=y
    # CONFIG_APM_IGNORE_USER_SUSPEND is not set
    CONFIG_APM_DO_ENABLE=y
    CONFIG_APM_CPU_IDLE=y
    # CONFIG_APM_DISPLAY_BLANK is not set
    CONFIG_APM_RTC_IS_GMT=y
    CONFIG_APM_ALLOW_INTS=y
    # CONFIG_APM_REAL_MODE_POWER_OFF is not set

    The APM_DISPLAY_BLANK could be what you need though I'm not really sure. I was only looking to get my pc to poweroff on shutdown. The help buttons should explain each option.

    There could be apm documentation in /usr/src/linux/Documentation that may explain what is required or perhaps searching Google ( www.google.com/linux ) may help.

    Hi Gaenya,
    Then you add the line to the
    Option "NoPM" "off" to your /etc/X11/XF86Config-4 file under the server section, or you can add the following to the server section:

    Option "BlankTime" "time"
    Option "StandbyTime" "time"
    Option "SuspendTime" "time"
    Option "OffTime" "time"

    where time is in minutes. hey - what game do you play with a joystick under linux?



    btw - nice avator label

    Ok, I have yet to understand how to do it so I guess a recap on all that is required would be more than welcome.

    In the mean time (I am a bit impatient) I looked around and found this:

    http://www-oss.fnal.gov/fss/document....7-5.i386.html

    It's graphical and very easy to set up. It works like a dream and I will be using it.

    Still I would like to find out the "proper" way.

    Thanks for all your time.
