############################################################################### # # Configuration for Laptop Mode Tools # ----------------------------------- # # There is a "system" to the configuration setting names: # CONTROL_something=0/1 Determines whether Laptop Mode Tools controls # something # LM_something=value Value of "something" when laptop mode is active # NOLM_something=value Value of "something" when laptop mode is NOT # active # AC_something=value Value of "something" when the computer is running # on AC power # BATT_something=value Value of "something when the computer is running # on battery power # # There can be combinations of LM_/NOLM_ and AC_/BATT_ prefixes, but the # available prefixes are different for each setting. The available ones are # documented in the manual page, laptop-mode.conf(8). If there is no LM_/ # NOLM_ in a setting name, then the value is used independently of laptop # mode state, and similarly, if there is no AC_/BATT_, then the value is used # independently of power state. # # Some options only work on ACPI systems. They are marked ACPI-ONLY. # # Note that this configuration file is a fragment of shell script: you # can use all the features of the shell scripting language to achieve your # desired configuration. # # # Modules # ------- # # Laptop Mode Tools modules have separate configuration files, that can be # found in /etc/laptop-mode/conf.d. Please look through these configuration # files as well, there are many useful power saving tools in there! # ###############################################################################
############################################################################### # Enable/Disable laptop-mode-tools execution # ------------------------------------------ # Set it to 0 to completely disable laptop-mode-tools from running ############################################################################### # ENABLE_LAPTOP_MODE_TOOLS=1
# # Set this to 1 if you want to see a lot of information when you start/stop # laptop_mode. # VERBOSE_OUTPUT=0
# Set this to 1 if you want to log messages to syslog LOG_TO_SYSLOG=1
# Run in shell debug mode # Enable this if you would like to execute the entire laptop-mode-tools program # in shell debug mode. Warning: This will create a lot of text output # If you are debugging an individual module, perhaps you would want to enable # each module specific debug mode (available in module conf files) DEBUG=0
############################################################################### # When to enable laptop mode # -------------------------- # # "Laptop mode" is the mode in which laptop mode tools makes the computer # consume less power. This includes the kernel "laptop_mode" feature, which # allows your hard drives to spin down, as well as various other settings which # can be tweaked by laptop mode tools. You can enable or disable all of these # settings using the CONTROL_... options further down in this config file. ###############################################################################
# # Enable laptop mode when on battery power. # ENABLE_LAPTOP_MODE_ON_BATTERY=1
# # Enable laptop mode when on AC power. # ENABLE_LAPTOP_MODE_ON_AC=0
# # Enable laptop mode when the laptop's lid is closed, even when we're on AC # power? (ACPI-ONLY) # ENABLE_LAPTOP_MODE_WHEN_LID_CLOSED=0
# # Enable all simple zero-configuration auto modules # This option enables all simple modules (listed below) without requiring # the user to enable each module individually # # List of modules which can be automatically enabled with this setting are: # # ac97-powersave # cpufreq # dpms-standby # eee-superhe # ethernet # exec-commands # hal-polling # hdparm # intel-hda-powersave # intel-sata-powermgmt # nmi-watchdog # runtime-pm # sched-mc-power-savings # sched-smt-power-savings # terminal-blanking # usb-autosuspend # wireless-ipw-power # wireless-iwl-power # wireless-power # # Set this to 1 to enable all simple zero-configuration auto modules listed above. # # NOTE: You can explicitly enable/disable any of the above modules by changing their # values in the individual settings file # ENABLE_AUTO_MODULES=auto
############################################################################### # When to enable data loss sensitive features # ------------------------------------------- # # When data loss sensitive features are disabled, laptop mode tools acts as if # laptop mode were disabled, for those features only. # # Data loss sensitive features include: # - laptop_mode (i.e., delayed writes) # - hard drive write cache # # All of the options that follow can be set to 0 in order to prevent laptop # mode tools from using them to stop data loss sensitive features. Use this # when you have a battery that reports the wrong information, that confuses # laptop mode tools. # # Disabling data loss sensitive features is ACPI-ONLY, and it only works if # your battery gives off frequent ACPI events to indicate a change in battery # level. # # NOTE: If your battery does NOT give off battery events often enough, you can # enable the battery-level-polling module to make this work. Look at the # file /etc/laptop-mode/conf.d/battery-level-polling.conf for more information. # ###############################################################################
# # Disable all data loss sensitive features when the battery level (in % of the # battery capacity) reaches this value. # MINIMUM_BATTERY_CHARGE_PERCENT=3
# # Disable data loss sensitive features when the battery reports its state # as "critical". # DISABLE_LAPTOP_MODE_ON_CRITICAL_BATTERY_LEVEL=1
############################################################################### # Controlled hard drives and partitions # ------------------------------------- # # For spinning down your hard drives, laptop mode will remount file systems and # adjust hard drive spindown timeouts. These parameters specify which # devices and partitions are affected by laptop mode. ###############################################################################
# # The drives that laptop mode controls. # Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a # wildcard, which will get you all your IDE and SCSI/SATA drives. # HD="/dev/[hs]d[abcdefgh]"
# # The partitions (or mount points) that laptop mode controls. # Separate the values by spaces. Use "auto" to indicate all partitions on drives # listed in HD. You can add things to "auto", e.g. "auto /dev/hdc3". You can # also specify mount points, e.g. "/mnt/data". # PARTITIONS="auto /dev/mapper/*"
# # If this is enabled, laptop mode tools will assume that SCSI drives are # really SATA drives that only _look_ like SCSI drives, and will use hdparm # to control them. Set this to 0 if you have /dev/sd devices and you want # laptop mode tools to use the "sdparm" command to control them. # ASSUME_SCSI_IS_SATA=1
############################################################################### # Hard drive behaviour settings # ----------------------------- # # These settings specify how laptop mode tools will adjust the various # parameters of your hard drives and file systems. ###############################################################################
# # Maximum time, in seconds, of work that you are prepared to lose when your # system crashes or power runs out. This is the maximum time that Laptop Mode # will keep unsaved data waiting in memory before spinning up your hard drive. # LM_BATT_MAX_LOST_WORK_SECONDS=600 LM_AC_MAX_LOST_WORK_SECONDS=360
# # Should laptop mode tools control readahead? # CONTROL_READAHEAD=1
# # Read-ahead, in kilobytes. You can spin down the disk while playing MP3/OGG # by setting the disk readahead to a reasonable size, e.g. 3072 (3 MB). # Effectively, the disk will read a complete MP3 at once, and will then spin # down while the MP3/OGG is playing. Don't set this too high, because the # readahead is applied to _all_ files that are read from disk. # LM_READAHEAD=3072 NOLM_READAHEAD=128
# # Should laptop mode tools add the "noatime" option to the mount options when # laptop mode is enabled? # CONTROL_NOATIME=0
# Should laptop use relatime instead of noatime? The "relatime" mount option has # more standards-compliant semantics, and allows more applications to work, # while retaining a low level of atime updates (i.e., disk writes). USE_RELATIME=1
# # Should laptop mode tools control the hard drive idle timeout settings? # CONTROL_HD_IDLE_TIMEOUT=1
# # Idle timeout values. (hdparm -S) # Default is 2 hours on AC (NOLM_HD_IDLE_TIMEOUT_SECONDS=7200) and 20 seconds # for battery and for AC with laptop mode on. # LM_AC_HD_IDLE_TIMEOUT_SECONDS=600 LM_BATT_HD_IDLE_TIMEOUT_SECONDS=60 NOLM_HD_IDLE_TIMEOUT_SECONDS=7200
# # Should laptop mode tools control the hard drive power management settings? # # Set to 0 to disable CONTROL_HD_POWERMGMT="auto"
# # Power management for HD (hdparm -B values) # BATT_HD_POWERMGMT=128 LM_AC_HD_POWERMGMT=254 NOLM_AC_HD_POWERMGMT=254
# # Should laptop mode tools control the hard drive write cache settings? # CONTROL_HD_WRITECACHE=0
# # Write cache settings for HD (hdparm -W values) # NOLM_AC_HD_WRITECACHE=1 NOLM_BATT_HD_WRITECACHE=0 LM_HD_WRITECACHE=0
############################################################################### # Settings you probably don't want to touch # ----------------------------------------- # # It is usually not necessary to change these parameters.

# # Dirty synchronous ratio. At this percentage of dirty pages the process # which calls write() does its own writeback. # LM_DIRTY_RATIO=60 NOLM_DIRTY_RATIO=40
# # Allowed dirty background ratio, in percent. Once DIRTY_RATIO has been # exceeded, the kernel will wake pdflush which will then reduce the amount # of dirty memory to dirty_background_ratio. Set this nice and low, so once # some writeout has commenced, we do a lot of it. # LM_DIRTY_BACKGROUND_RATIO=1 NOLM_DIRTY_BACKGROUND_RATIO=10
# # kernel default settings -- don't touch these unless you know what you're # doing. # DEF_UPDATE=5 DEF_XFS_AGE_BUFFER=15 DEF_XFS_SYNC_INTERVAL=30 DEF_XFS_BUFD_INTERVAL=1 DEF_MAX_AGE=30
# # This must be adjusted manually to the value of HZ in the running kernel # on 2.4, until the XFS people change their 2.4 external interfaces to work in # centisecs. This can be automated, but it's a work in progress that still # needs some fixes. On 2.6 kernels, XFS uses USER_HZ instead of HZ for # external interfaces, and that is currently always set to 100. So you don't # need to change this on 2.6. # XFS_HZ=100
