<chapter id="introduction">
<title>The &kcontrolcenter;</title>

<para>
The &kcontrolcenter; (from now on referred to simply as <quote>the
control center</quote>) provides you with a centralized and convenient
way to configure all of your &kde; settings.
</para>

<para>
The control center is made up of multiple modules.  Each module is a
separate application, but the control center organizes all of these
programs into a convenient location.
</para>

<tip>
<para>
Each control center module can be executed individually
</para>

<para>
See section entitled <link linkend="control-center-run-indiv">Running
individual control center modules</link> for more information.
</para>
</tip>

<para>
The control center groups the configuration modules into categories, so
they are easy to locate.  Within each category, the control center shows
all the modules in a list, so it is easier to find the right
configuration module.
</para>
</chapter>

<chapter id="control-center">
<title>Using The &kcontrolcenter;</title>

<para>
This next section details the use of the control center itself.  For

Center Modules</link>

<title>Laptop Modules Notes</title>

<para>
In order to use the laptop modules, you must have the kernel
<acronym>APM</acronym> package installed in your kernel.  Useful information 

on
how to do this can be found at
<ulink url="http://www.cs.utexas.edu/users/kharker/linux-laptop/apm.html">
http://www.cs.utexas.edu/users/kharker/linux-laptop/apm.html</ulink> and
in the Battery Powered Linux mini-HOWTO at <ulink
url="http://metalab.unc.edu/LDP/HOWTO/mini/Battery-Powered.html">
http://metalab.unc.edu/LDP/HOWTO/mini/Battery-Powered.html</ulink>.
</para>

<para>
If you want the <guimenuitem>suspend</guimenuitem> and
<guimenuitem>standby</guimenuitem> menu commands to work then you should
install the &Linux; <application>apmd</application> package (version 2.4
or later). If you want to use them from non-root accounts you must mark
the <application>apm</application> command <quote>set uid root</quote>.
</para>

<para>
To do this, log on as <systemitem class="username">root</systemitem> and 
enter:
</para>

<screen>
<prompt>%</prompt><userinput><command>chown</command> <option>root 
/usr/bin/apm</option>;<command>chmod</command> <option>+s 
/usr/bin/apm</option></userinput>
</screen>

<warning>
<para>
By doing this you will allow any user of your system to put it into suspend 
or
standby states - if you are the only user, this should not be a problem.
</para>

<para>
Also note that any program which has <systemitem
class="username">root</systemitem> access, can be a potential security
problem.  You should carefully determine if there are any security
concerns <emphasis>before</emphasis> giving any program <systemitem
class="username">root</systemitem> permissions.
