NAME

kded6 - KDE daemon - triggers Sycoca database updates when needed.

SYNOPSIS

kded6 [--check]

DESCRIPTION

kded6 consolidates several small services in one process. These are mostly D-Bus services provided by KDED modules, but it also manages sycoca (a binary cache of servicetypes, MIME types and services used by KService) and KConfig update scripts as needed.

For sycoca, 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 kbuildsycoca6 to update the sycoca.

For KConfig, it checks newly-installed update files, i.e. the *.upd files used to update configuration files of users when the configuration file formats changes, and runs the KConfig update utility to perform the updates.

Those tasks are also run when kded6 is started to ensure that the user configuration is up to date.

You do not normally need to run kded6 directly; Plasma desktop sessions run it automatically, and it is started on demand when an application attempts to use a D-Bus interface provided by it or one of its modules.

OPTIONS

--check

Check the sycoca database, updating it if necessary, and exit.

CONFIGURATION

kded6 can be configured with the kded6rc ini-style configuration file. On UNIX® systems, this can be found at $XDG_CONFIG_HOME/kded6rc; if $XDG_CONFIG_HOME is not set, this defaults to ~/.config/kded6rc.

Configuration file entries are read on-demand, so changes can be made while kded6 is running. However, all the current configuration options only really affect the startup behaviour of kded6.

The [General] section has the following options:

CheckSycoca

Whether to update sycoca at startup (default: true).

CheckUpdates

Whether to perform outstanding KConfig updates at startup (default: true).

CheckFileStamps

Whether to check file timestamps when performing the initial sycoca update (default: true). See the documentation for kbuildsycoca6 for more details.

DelayedCheck

Whether to delay the initial sycoca update until about a minute after starting (default: false).

Each module also has a [Module-name] section in kded6rc, where name is the name of the module's desktop file without the .desktop extension. This contains an autoload option that specifies whether the module should be automatically loaded when kded6 is started (default: false). Note that this setting can also be changed via kded6's D-Bus interface.
