    Power management, always blanking screen?!

    Hi,

    I have an ASUS A6 series notebook with a 256MB ATI Radeon X1600 built in.
    I am running Ubuntu - Hardy

    The problem I am having is that regardless of what my power management settings say, my screen always blanks after 5minutes of being idle.
    I am happy for the screen to blank when the power adapter is not plugged in, but if the adapter is plugged in, I dont want the screen to blank out.

    Below is a screen shot of my power settings and screen saver settings:


    Is there some other configuration hiding somewhere?
    Appreciate any help.

    Thanks,
    occhiso

    Do you have ATI Catalyst installed? If you do check it. If not install it and check it. There may be a switch in there.

    Try this:
    Code:
    gksudo gedit /etc/X11/xorg.conf
    Copy and paste this into the file :
    Section "ServerFlags"
    Option "BlankTime" "0"
    Option "StandbyTime" "0"
    Option "SuspendTime" "0"
    Option "OffTime" "0"
    EndSection
    Also, look at all of the gnome power-manager settings with:
    Code:
    gconf-editor
    The path is /apps/gnome-power-manager

    If that doesn't work, it could have something to do with ACPI.

    Hi Temüjin,

    I pasted that code into my xorg.conf file and it looks like it fixed it.
    Thanks for your help
