LM-PROFILER(8)						      System Manager's Manual						    LM-PROFILER(8)

NAME

       /usr/sbin/lm-profiler - laptop mode profiler

SYNOPSIS

       /usr/sbin/lm-profiler

DESCRIPTION

       This  manual page documents briefly the /usr/sbin/lm-profiler command. lm-profiler is a tool for profiling disk operations. It is a part of
       laptop mode tools and is useful only in relation to rest of laptop mode tools. It helps you to detect programs and  services  that  use	up
       system resources and that cause disk activity, and it allows you to disable them when laptop mode is active.

       When  you start lm-profiler, it will execute a "profiling run", which can take some time. Start lm-profiler when you are working on batter-
       ies, preferably, because that will allow it to analyze the actual situation that it is supposed to optimize. During the profiling run,  you
       can  use  your system normally; however, any disk activity caused by your actions will end up in the profiler's results. When the profiling
       run is finished, you will be presented with a list of programs that deserve your attention, either because they listen on a network  (which
       is  not	usually  useful when you are working offline) or because they caused disk activity in a disk-spindown-unfriendly pattern. When lm-
       profiler can guess an init script that belongs to a program, it presents you with the opportunity to disable the program when you are work-
       ing  on battery. It does this by placing a link to the init script in /etc/laptop-mode/batt-stop. Any programs that lm-profiler cannot find
       an init script for is simply reported, so that you can stop the program manually if you want to.

       WARNING ABOUT DISABLING PROGRAMS: It may not be safe to disable some programs. They may be needed for proper operation of your system. Dis-
       able services only if you know what they do and why you don't need them.

NAME

       /usr/sbin/laptop_mode - apply laptop mode settings

SYNOPSIS

       /usr/sbin/laptop_mode [ cmd ] [ force ]

DESCRIPTION

       This  manual  page  documents  briefly  the  /usr/sbin/laptop_mode command. laptop_mode is a program that applies the settings given in the
       /etc/laptop-mode/laptop-mode.conf configuration file. The primary use is to control the laptop mode feature included in Linux kernels  with
       versions  2.6.6	and  higher,  and  2.4.23  and	higher.  This feature increases battery life by letting your hard drive spin down. This is
       achieved by grouping disk write activity into "chunks" that are spaced at larger intervals than they normally would be. In addition to sup-
       porting	the  Linux  kernel's  laptop  mode  feature, /usr/sbin/laptop_mode also supports various power saving modules which are configured
       through configuration files in the /etc/laptop-mode/conf.d directory.

       It is not recommended to call /usr/sbin/laptop_mode directly to start or stop laptop mode, except in hardware event handlers. To apply  new
       configuration settings from laptop-mode.conf, call the laptop-mode service init script with the reload parameter.

COMMANDS

       Specify force as the second parameter to force laptop_mode to re-apply a state even if the computer is already in that state. These are the
       values that are allowed for cmd :

       auto	 Enable or disable laptop mode based on the current power state. Note that this will not do anything if  the  laptop-mode  service
		 has not been started!

       status	 Display a status report about everything that laptop_mode affects.
