Is it wrong this worries me?
Well, my old laptop flopped over and died, so I reinstalled Linux on a new one. I decided to try Gnome, since it'd been a long time since I tried any kind of large-scale window manager. It turns out "gnome" is somewhat apropos. When using it you'll feel like there's a tiny homonid wandering around your system doing things where you can't see.

I was able to play audio when logged into gnome, but unable to do so when logged in through a raw console. Not being able to do so in a raw console made sense when I figured it out -- I forgot to add myself to the 'audio' group -- but that meant it shouldn't work in Gnome either! The 'groups' command confirmed Gnome hadn't added me back somehow... I had to do a lot of digging to find out what it was actually doing.

Gnome uses "Consolekit" to manage login permissions, which lets it do things like XP-style fast user switching. Consolekit has tentacles in a whole lot of things: It's got the cooperation of PAM, X11, and dbus, as well as its very own system service.

Through the collusion of all these things it's able to give my own login access to things my login credentials don't without me even having to ask for them. That strikes me as extremely wrong.

LAPTOP_MODE(8)						      System Manager's Manual						    LAPTOP_MODE(8)

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.

SEE ALSO

       laptop-mode.conf(8).
