kdeinit4 - KDE process launcher. SYNOPSIS
kdeinit4 [--help] [[--no-fork] | [--no-kded] | [--suicide]] [[+programs] | [programs]] DESCRIPTION
kdeinit4 is a process launcher somewhat similar to the famous init used for booting UNIX. It executes KDE programs and kdeinit loadable modules (KLMs) starting them more efficiently. Using kdeinit4 to launch KDE applications makes starting a typical KDE application a couple times faster and reduces memory consumption by a substantial amount. kdeinit4 is linked against all libraries a standard KDE application needs. With this technique, starting an application becomes much faster because now only the application itself needs to be linked whereas otherwise both the application as well as all the libaries it uses need to be linked. DISADVANTAGES
The process name of applications started via kdeinit4 is "kdeinit4". This problem can be corrected to a degree by changing the application name as shown by ps. However, applications like killall will only see kdeinit4 as the process name. To workaround this, use kdekillall (from kdesdk/scripts) for applications started via kdeinit4. OPTIONS
--help Show help about options --no-fork Do not fork, i.e. do not exit until all the executed programs ends --no-kded Do not start kded --suicide Terminate when no KDE applications are left running +programs runs the programs handling requests programs runs the programs without handling requests USAGE
A standard way to run this program is by simply specifying the following command at the prompt kdeinit4 program or kdeinit4 +program FILES
$HOME Specifies the home directory of the current user $KDE_HOME_READONLY Specifies if the home directory of the current user is read only $KDE_IS_PRELINKED If set, tells kdeinit4 that the KDE programs are pre-linked. (Prelinking is a process that allows you to speed up the process of dynamic linking.) $KDE_DISPLAY If set, tells kdeinit4 that it is running on a KDE desktop. SEE ALSO
kded, kdekillall BUGS
There are probably tons of bugs. Use[1] to report them. AUTHORS

kded4 - KDE daemon - triggers Sycoca database updates when needed. SYNOPSIS
kded4 [--help] [Generic options] [Qt-options] [KDE-options] [--check] DESCRIPTION
kded4 is responsible for creating the sycoca file, i.e. the binary cache of servicetypes, mimetypes, and services for a particular user. It monitors the directories containing .desktop files. When a file is added/removed, it waits 5 seconds (in case of a series of updates), and then launches kbuildsycoca4 to update the sycoca. It checks newly installed update files, i.e. the *.upd files used to update configuration files of users when the configuration file formats changes. kconf_update is launched to do the updates. When the hostname changes, it will make the necessary changes to the KDE environment and X-server to allow continued proper operation, launching kdontchangethehostname to do the changes. Those tasks are also performed always at kded4 start to ensure that the user configuration is up to date. It is also responsible for launching the on-demand kded4 modules and init enabled kded4 modules like: Konqueror Browser Preloader Reduces Konqueror startup time. Directory Watcher Monitors directories for changes. Hardware Detection Provides a user interface for hardware events. SSL Certificate Policy Provides the user configured SSL certificate policy to applications. Network Proxy Configuration Automatic proxy configuration. Password Caching Temporary password caching, for example: so that a webpage with HTTP authentication doesn't ask for your password for every link and every image in the page. These passwords are forgotten when exiting KDE (unlike KWallet) Sound Policy Provides the sound system policy to applications. Favicons Stores website icons. Display Management Manages displays and video outputs. Cookie jar Stores network cookies. Network Watcher Keeps track of the network and updates directory listings of the network:/ KIO slave. Subversion Module Provides various subversion actions to filemanager and other software. Network Status Tracks status of network interfaces and provides notifications for applications using the network. Write Daemon Watches the messages from local users sent with write(1) or wall(1). Notification area watcher Keeps track of applications that want to use the D-Bus based notification area. KMixD KMixD Mixer Service Systemtray daemon Keeps track of applications that want to use the D-Bus based system tray. Keyboard Daemon Keeps track of keyboard changes (new keyboard, changed layout) Remote URL Change Notifier Provides change notifications for network folders Activity Manager The Nepomuk activities manager backend Display Management change monitor Notifies how the display has been rotated (where available) Free Space Notifier Warns when running out of space in your home folder. Removable Device Automounter Automatically mounts devices as needed. Nepomuk Search Module Helper module for KIO to ensure automatic updates of Nepomuk search listings. Power Management Battery, Display and CPU power management and notifications. K Remote Control Daemon Manages the Remote Control commands received Status Notifier Manager Manages services that provide status notifier user interfaces. DNS-SD Service Discovery Monitor Monitors the network for DNS-SD services. Drive Ejector Automatically unmounts and releases drives when their eject button is pushed. Time zone Provides access to the system's time zones for applications. Input Actions Input Actions service performing configured actions on key presses. The init modules can be enabled/disabled using systemsettings, in System Administration > Startup and Shutdown > Service Manager. GENERIC OPTIONS
--author Show author information. --help Show help about options. --help-all Show all options. --help-kde Show KDE specific options. --help-qt Show Qt specific options. --license Show license information. -v --version Show version information APPLICATION OPTIONS
--check Check Sycoca database only once. USAGE
If kded4 is called without parameters and is already running, it shows the message: KDE Daemon (kded) already running. If kded4 is called with kded4 --check, then it updates the KDE sycoca using kbuildsycoca4. SEE ALSO
