The &kcontrolcenter;
The &kcontrolcenter;
The &kcontrolcenter; is the place to go to change any settings that
affect the whole of your &kde; environment. You can open it using the
Control Center item in the &kmenu;, or with its
command-line name, kcontrol.
The settings are divided into several major categories, which each
contain several pages of settings. To display a settings page, expand the
major category by clicking on the + button next to it,
and then click on the name of the page you want. The settings page then
appears on the right, and you can change settings to your heart's
content. No changes take effect until you click on the
Apply button. If you decide, after making some
changes, that you want to leave the settings as they were, just click on
Reset.
If you need more help with a page, visit that page, then click on the
Help tab. You might also want to look at the
&kcontrolcenter; Handbook, which you can open with the
Help&kcontrolcenter;

network. Some of it's features are being able to set up an 'answering
machine' that will email to you messages left for you, and being able to
forward messages to another location.
Proxy
This is where you would configure &kde; to connect to a proxy server
rather than directly to the internet. Once again you would generally leave
these options at their defaults unless you really knew what you were
doing. If you do use a proxy server your network administrator will be able
to tell you what details to fill in here.
Samba
The Samba Configuration module requires the
root or administrator password. It is
an advanced configuration tool that allows you to control Samba's security,
shares, users and printers in an intuitive graphical interface. This is a

powerful and configurable file management tool with a plethora of
options. For more information, consult the &konqueror; handbook.
KDE Performance
Here are settings related to the memory usage of
&konqueror;. Minimize Memory Usage allows you to
control whether separate instances of &konqueror; will open or whether all
new &konqueror; windows connect to the same instance. This has the effect of
reducing memory usage. You can also select whether to pre-load &konqueror;
after &kde; startup, to reduce start times.

Security & Privacy
This section is where you can configure options related to
security and privacy such as the use of cryptography, enabling the KDE
wallet, setting your identity and managing caches.
Crypto
This module allows you to configure SSl for use with most
KDE applications, as well as manage your personal certificates
and the known certificate authorities.
KDE Wallet
Here you can change your KDE Wallet Manager settings.
KDE Wallet aims to provide secure storage for passwords and web form data.
You can group different passwords in different wallets, and each one will only
be opened with a master password (which you should never forget!). The
default wallet is named "kdewallet", and you can either create a new wallet
for your local passwords or accept the default wallet for all data in
the "Automatic Wallet Selection" section.
KDE programs like Konqueror, Kmail and Kopete are fully compatible with
the KDE Wallet Manager. All of them will ask at least once for permission to
access to actual wallet. You can give different access levels, such as "always
allow", "allow once", etc. If you want to change that access level, you can do
it from the "Access Control" tab by deleting the program entry and selecting a
new preference the next time that application requests access to the
wallet.
Wallet Preferences
To enable the KDE wallet subsystem, check the
Enable the KDE wallet subsystem box.
Unchecking this box will disable the KDE Wallet on your system.
By default, KDE Wallet Manager is kept opened until the
user session is closed, but you can change that in the Close
Wallet section to close it when unused for a time, when a screen
saver starts or when the last application stops using it.
As you can have several wallets, Automatic Wallet
Selection allows you start KDE with a given wallet.
KDE Wallet will appear in your system tray by default, but you can hide
it. Uncheck Show manager in the system tray to keep it
always hidden, or check Hide system tray icon when last wallet
closes to hide it only when all wallets are closed. These items are
in the Wallet Manager section.
Access Control
You can set here what policy you want for your
KDE applications, regarding to the wallet use.
Password & User Account
You can change here your personal information
which will be used in mail programs and word processors. You
can change your login password by clicking the Change
Password... button.
Privacy
This module allows you to erase traces which
KDE leaves on your system such as command histories or
browser caches.

have installed. By default, it displays personal fonts. To modify system-wide fonts click the Administrator Mode button.
IBM Thinkpad Laptop
This configuration module allows you to configure the special keys on an IBM thinkpad
laptop. You will need the nvram
module to use these features.

configuration files for a &Linux; kernel. This configurator is compatible with kernels previous to 2.5.
Login Manager
This module allows you to configure the &kde; login manager, &kdm;. &kdm; is
a powerful login manager with a large range of options. It supports user switching, remote graphical logins and has a fully customizable appearance. For more information, see the &kdm; handbook.
Paths
This dialog allows you to configure the default locations where certain
important files are kept. The Desktop directory contains all the files on your desktop. The Autostart directory contains files or links to files that you want run when &kde; starts, and the Documents directory is the default location &kde; applications will open or save documents to.
Sony Vaio Laptop
This configuration module allows you to configure features specific to
Sony Vaio laptops. If you have a Sony Vaio, you will have to install the sonypi
driver to use this section.
