Boas pessoal estou a tentar meter o modo laptop activo no meu portatil mas não estou a conseguir!
joao@acer-laptop:~$ cat /proc/sys/vm/laptop_mode
0
Mas eu já activei o modo laptop no /etc/default/acpi-support!
Esta é a minha configuração do acpi-support
#
# Configuration file for the acpi-support package
#
#
# The acpi-support package is intended as "glue" to make special functions of
# laptops work. Specifically, it translates special function keys for some
# laptop models into actions or generic function key presses.
#
#
# Suspend/hibernate method
# ------------------------
#
# When gnome-power-manager or klaptopdaemon are running, acpi-support will
# translate the suspend and hibernate keys of laptops into special "suspend"
# and "hibernate" keys that these daemons handle.
#
# Only in situations where there is no gnome-power-manager or klaptopdaemon
# running, acpi-support needs to perform suspend/hibernate in some other way.
# There are several options for this. The options are:
#
# dbus-pm:
# Perform suspend and hibernate actions via a DBUS request to the power
# management daemon. This works for power management daemons that we don't
# know of. (For gnome-power-manager and klaptopdaemon this will do nothing,
# since those will be detected when they are running, and triggered using
# a virtual keypress.)
#
# dbus-hal:
# Perform suspend and hibernate actions via a DBUS request directly to HAL,
# bypassing any running power management daemons.
#
# pm-utils:
# Use pm-suspend and pm-hibernate to suspend and hibernate. (The dbus method
# normally results in this as well, but calls through dbus. Use this option
# only if you don't have dbus installed.)
#
# hibernate:
# Use the hibernate package to suspend and hibernate.
#
# acpi-support:
# Use the legacy built-in suspend/hibernate support. (DEPRECATED)
#
# none:
# Do not attempt to suspend/hibernate. Set SUSPEND_METHODS="none" to
# disable suspend/hibernate handling in acpi-support.
#
# If you specify dbus or pm-utils, the result will normally be the same as when
# you suspend from your desktop environment. If you specify "hibernate" or
# "acpi-support", be aware that this probably does not match what your desktop
# environment would do (unless you have managed to configure something so that
# the DBUS power management interfaces call the hibernate package).
#
#
# 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
# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines. (Note: This is reported to cause breakage in
# Debian - see deb bug #425800. Leaving enabled for Ubuntu for now
# since presumably it's still valid here.)
ENABLE_LAPTOP_MODE=true
# 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.
O que é que me falta fazer!
