Nastavení Laptop Módu

[jirka.jirka.]

Zdar chlapi.
Tak jsem po nějaké době opět vyzkoušel Kubuntu. Docela se mi líbí. Nainstaloval jsem ho na notebook. Zatím to šlape jak má, ale mám problém s diskem. Poměrně dost hřeje. Tak jsem kolem toho pátral, a zjistil jsem, že za to prej může časté parkování hlaviček. Tak než se pustím do něčeho velkého, tak jsem si řekl, že si to zkusím nanečisto ve VirtualBoxu. Nainstaloval jsem laptop_mod

Kód: [Vybrat]

sudo apt-get install laptop-mode-tools Tam jsem si aktivoval laptop mód v souboru:

Kód: [Vybrat]

/etc/default/acpi-support pomocí tohoto:
# Switch to laptop-mode on battery power – off by default as it causes odd
# hangs on some machines.
ENABLE_LAPTOP_MODE=true

Ale teď se prej má něco nastavit v

Kód: [Vybrat]

/etc/laptop-mode/laptop-mode.conf, ale tady nevím co. Pro jistotu tady přídám celý svůj laptop-mode.conf. Snad se najde někdo, by mi řekl co a jak.

  # 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(. 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!

  # 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
  # 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=1
  
  
  
  ###############################################################################
  # 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.
  #

  #
  # 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

  # parameters of your hard drives and file systems.

  # 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

V první fázi bys měl dát výpis do závorek, kdo se s tím má číst.

Tak teď nemám ani ponětí co tím myslíš.

Konkretne code  a  /code v hranatych zatvorkach. Tak ako to mas na zaciatku.

Doufám že jsi to myslel nějak takto. Pokusil jsem se to rozdělit tak nějak do jednotlivých sekcí, jak je tomu přímo v tom souboru. A doufám, že ty komentáře nebudou důležité. Jestli jo, tak je doplním.
