I want to set my desktop so that only the video will turn off if it isn't
used for a while. I googled and found :

      *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:
followed by

So I thought to myself that this must be the way.

So this is what my how my acpi-support reads. Will this do what I want it
to do?


# Please specify a space separated list of options. The recommended value is
# "dbus pm-utils"

#SUSPEND_METHODS="dbus-pm dbus-hal pm-utils"

# LEGACY BUILT IN SUSPEND SUPPORT (DEPRECATED)
# --------------------------------------------
#
# These options only work for the "acpi-support" suspend method. This is NOT
# recommended, but is retained for backward compatibility reasons.
#

# Comment the next line to disable ACPI suspend to RAM
#ACPI_SLEEP=true

# Comment the next line to disable suspend to disk
#ACPI_HIBERNATE=true

# Change the following to "standby" to use ACPI S1 sleep, rather than S3.
# This will save less power, but may work on more machines
#ACPI_SLEEP_MODE=mem

# 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
#MODULES=""

# Add modules to this list to leave them in the kernel over suspend/resume
#MODULES_WHITELIST=""

# Should we save and restore state using the VESA BIOS Extensions?
#SAVE_VBE_STATE=true

# The file that we use to save the vbestate
#VBESTATE=/var/lib/acpi-support/vbestate

# Should we attempt to warm-boot the video hardware on resume?
#POST_VIDEO=true

# Save and restore video state?
# SAVE_VIDEO_PCI_STATE=true

# Should we switch the screen off with DPMS on suspend?
#USE_DPMS=true

# 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.
# DOUBLE_CONSOLE_SWITCH=true

# Set the following to "platform" if you want to use ACPI to shut down
# your machine on hibernation
#HIBERNATE_MODE=shutdown

# Comment this out to disable screen locking on resume
#LOCK_SCREEN=true

# 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.
#STOP_SERVICES=""

# Restart Infra Red services on resume - off by default as it crashes some
# machines
#RESTART_IRDA=false

# Add to this list network interfaces that you don't want to be stopped
# during suspend (in fact any network interface whose name starts with
# a prefix given in this list is skipped)
#SKIP_INTERFACES="dummy qemu"

# Note: to enable "laptop mode" (to spin down your hard drive for longer
# periods of time), install the laptop-mode-tools package and configure it
in
/etc/laptop-mode/laptop-mode.conf.
