    Disable sleep/standby/display sleep

    I have an HTPC with a Gigabyte GA-MA78GM-S2H board and Athlon 64. I have it connected via HDMI to my TV, and only control it using a remote. However, after about 15 minutes, some sleep mode is activated, and the HDMI signal cuts out until I wiggle/click the mouse.

    I have the screensaver disabled in the Screensaver page of the Settings Manager, so it's not that.

    My /etc/default/acpi-support reads:
    # Comment the next line to disable ACPI suspend to RAM
    # Comment the next line to disable suspend to disk
    # Change the following to "standby" to use ACPI S1 sleep, rather than S3.
    # This will save less power, but may work on more machines
    # Add modules to this list to have them removed before suspend and reloaded
    # on resume. An example would be MODULES="em8300 yenta_socket"
    # Note that network cards and USB controllers will automatically be unloaded
    # unless they're listed in MODULES_WHITELIST
    # Add modules to this list to leave them in the kernel over suspend/resume
    # Should we save and restore state using the VESA BIOS Extensions?
    # The file that we use to save the vbestate
    # Should we attempt to warm-boot the video hardware on resume?
    # Save and restore video state?
    # Should we switch the screen off with DPMS on suspend?
    # Use Radeontool to switch the screen off? Seems to be needed on some machines
    # RADEON_LIGHT=true
    # Uncomment the next line to switch away from X and back again after resume.
    # This is needed for some hardware, but should be unnecessary on most.
    # Set the following to "platform" if you want to use ACPI to shut down
    # your machine on hibernation
    # Comment this out to disable screen locking on resume
    # Uncomment this line to have DMA disabled before suspend and reenabled
    # afterwards
    # DISABLE_DMA=true
    # Uncomment this line to attempt to reset the drive on resume. This seems
    # to be needed for some Sonys
    # RESET_DRIVE=true
    # Add services to this list to stop them before suspend and restart them in
    # the resume process.
    # Restart Infra Red services on resume - off by default as it crashes some
    # machines
    # Spindown time on battery
    Since commenting out the ACPI_SLEEP, ACPI_HIBERNATE, and USE_DPMS lines, I've restarted acpid and acpi-support, with no effect.

    I'd rather not turn power management off entirely (I still want the ability to turn the machine off and all that), but I don't want to have it going to sleep after 15 minutes.

    How about System->Preferences->Power Management then change the time before the display sleeps?

    I installed gnome-power-manager (I assume that's where System->Preferences->Power Management comes from) and ran gnome-power-preferences. Both display sleep and system sleep are set to Never.

    I'm testing with the instructions in this thread:

    I also put an early-out exit; in /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux, power-suspend-hybrid-linux, power-hibernate-linux, and power-set-power-save-linux, as well as /etc/acpi/

    Hopefully this will work.
