    Thanks! I tried that swsusp stuff, but when I run the script, it writes
    "going to hibernate", and unloading everything, and stopping daemons,
    and killing programs, and umounting drives :), but it doesn't hibernate
    the system, instead reloads everything, and says came back from
    hibernate. Anyway it's doc's says the 2.4.x kernels doesn't fully
    support suspend to ram, and suspend to disk. But (think again) I don't
    need these anyway.
    I need a program (or programs), which I can use to control the acpi from
    command-line. For example turning the monitor to suspend state (ie.:
    ./acpi_ctrl -vga , or something like that :). I read that I can control
    the systems sleep state by writing numbers to /proc/acpi/sleep. This is
    another story, and it isn't fully working :)
    I can control my hard-drives suspend time with hdparm -S, and my cpu's
    throttling state with /proc/acpi/processor/CPU0/throttling. The only
    thing I need is a way to manually send my monitor to suspend state. Is
    this possible with some program?
    And another question for clearing my mind:
    What is the difference between the monitors standby, suspend, and off
    mode (I can see these in my kde control center). From the outside those
    are all the same. All of the above states, are switching my monitor off,
    but not completely (I can see the led shining on my monitor, but in
    another color).

    Ok, hope that someone can help, and answer these qustions.

    Thanks!

    Daniel
