Welcome to this readme about KDED.
|
|
|
|
KDED stands for KDE Daemon which isn't very descriptive.
|
|
KDED runs in the background and performs a number of small tasks.
|
|
Some of these tasks are built in, others are started on demand.
|
|
|
|
Built in tasks
|
|
==============
|
|
*) Checking for newly installed software and updating ksycoca when new
|
|
software is detected. Updating of ksycoca is done by the program kbuildsycoca
|
|
which gets started by kded. When kded is first started it always runs
|
|
kbuildsycoca to ensure that ksycoca is up to date.
|
|
|
|
*) Checking for hostname changes. It is a really bad idea to change the
|
|
hostname of a running system and it usually only happens with incorrectly
|
|
configured dial-up connections. Never the less, kded will check for hostname
|
|
changes and if it detects one it will make the necassery changes to the
|
|
KDE environemnt and X-server to allow continued proper operation. The
|
|
program kdontchangethehostname is executed to make the actual changes.
|
|
|
|
Configuration of built in tasks.
|
|
================================
|
|
The built in tasks have some configuration options that can be changed by
|
|
editing the kdedrc configuration file. Changes need to be made with a text-
|
|
editor, there is no GUI available. All options are listed under the [General]
|
|
group:
|
|
|
|
HostnamePollInterval: This can be used to adjust the time interval at which
|
|
the hostname is checked for changes. The time is specified in milliseconds
|
|
and has a default of 5000 (5 seconds).
|
|
|
|
CheckSycoca: This option can be used to disable checking for new software.
|
|
ksycoca will still be built when kded starts up and when applications
|
|
explicitly request a rebuild of the ksycoca database. The user can
|
|
also manually rebuild ksycoca by running the kbuildsycoca program.
|
|
The default value of this option is "true". Checking can be disabled by
|
|
setting this option to "false".
|
|
|
|
CheckHostname: This option can be used to disable checking for hostname
|
|
changes. The default value of this option is "true". Checking can be
|
|
disabled by setting this option to "false".
|
|
|
|
Example kdedrc file with default values:
|
|
|
|
[General]
|
|
HostnamePollInterval=5000
|
|
CheckSycoca=true
|
|
CheckHostname=true
|
|
CheckFileStamps=true
|
|
|
|
The filesystem will be polled at regular interval for any changes.
|
|
|
|
KDED modules
|
|
============
|
|
Some things can be greatly simplified if they can be coordinated from a
|
|
central place. KDED has support for modules that will be demand-loaded
|
|
whenever an application attempts to make DBus call to the module.
|
|
This can be useful for central administration tasks.
