- # 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 bash shell script: you
- # can use all the features of the bash scripting language to achieve your
- # desired configuration.

- # 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.

- # 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.

- # Controlled hard drives and partitions

-
- # If this is enabled, laptop mode tools will assume that SCSI drives are really

- # Syslog configuration control
- # ----------------------------

- # Using the following options, you can let laptop mode switch between
- # different syslog configurations depending on whether you are working on
