    Smile lxde (not full lubuntu) set screen blankout on Dell D430

    I haven't been able to do this successfully, but I just found that in /etc/acpi there are various sh scripts that control power options. For screenblank it looks like this:

    Code:
    #!/bin/sh
    
    test -f /usr/share/acpi-support/key-constants || exit 0
    
    . /etc/default/acpi-support
    . /usr/share/acpi-support/power-funcs
    
    for x in /tmp/.X11-unix/*; do
        displaynum=`echo $x | sed s#/tmp/.X11-unix/X##`
        getXuser;
        if [ x"$XAUTHORITY" != x"" ]; then
            export DISPLAY=":$displaynum"
        . /usr/share/acpi-support/screenblank
        fi
    done
    Looks like maybe I need to look in /usr/share/acpi-support/key-constants or . /usr/share/acpi-support/power-funcs


    Any help?

    OKay I see this script doesn't determine when to blank the screen (after running it), it just blanks the screen. Now to figure out what programs call this script.

    I see that in /etc/UPower/UPower.conf it says "# Only the system vendor should modify this file, ordinary users
    # should not have to change anything.", but I am tempted to change the timeout value here.

    I thought I had this solved by changing the number in that file btut it seems not allways to work. putting on backburner
