| == Introduction ==
| | {{Moved To Userbase}} |
| There are numerous environment variables that are useful when managing and controlling a KDE environment. Supported environment variables are listed below.
| |
| | |
| == Automatically Set Variables ==
| |
| | |
| === KDE_FULL_SESSION ===
| |
| Set to true by KDE startup, it is used by some programs, such as Konqueror, to know if they should consider remaining in memory for future re-use when being closed. If not set, those programs will exit after being closed (e.g. kdesu does that, it's also useful for debugging).
| |
| | |
| If you plan on using this variable to detect a running KDE session, check if the value is not empty instead of seeing if it equals true. The value might be changed in the future to include KDE version information.
| |
| | |
| === KDE_SESSION_VERSION ===
| |
| Introduced in KDE4, this environment variable is set to the major version number of the KDE desktop being run on startup. This allows one to know which <tt>kde?-config</tt> to run: <tt>kde${KDE_SESSION_VERSION}-config</tt>. For KDE3 this will resolve to <tt>kde-config</tt> and for KDE4 this will result in <tt>kde4-config</tt>. One can then use this knowledge to query more details, such as the minor version, prefixes, etc.
| |
| | |
| == Display and Window Management ==
| |
| | |
| === KDEWM ===
| |
| If the KDEWM environment variable has been set, then its value will be used instead of <tt>kwin</tt> as KDE's window manager within the startkde script.
| |
|
| |
| === KDE_DISPLAY ===
| |
| An old(?) way to set DISPLAY for multihead.
| |
|
| |
| === KDE_MULTIHEAD ===
| |
| Set this variable to true to indicate that KDE is running on a multi-head system.
| |
|
| |
| | |
| == File System ==
| |
| | |
| === KDEDIRS ===
| |
| Overrides KDEDIR and allows you to specify multiple directories where KDE searches for its data. Useful if you want or have to install some programs to a different prefix than the rest of your KDE.
| |
|
| |
| Please note that at least the startkde script expects the KDE install directory to be listed first.
| |
|
| |
| === KDEHOME ===
| |
| If not set, KDE uses ~/.kde as directory where your personal data is stored.
| |
|
| |
| === KDE_HOME_READONLY ===
| |
| Set this variable to indicate that your home directory is mounted read-only.
| |
| | |
| === KDEROOTHOME ===
| |
| If not set, KDE uses ~root/.kde for root's personal data. This was introduced to prevent KDE from accidentally overwriting user data with root permissions when a user runs a KDE program after switching to root with "su".
| |
| | |
| === KDESYCOCA ===
| |
| Allows you to specify the path and the name of the generated KDE configuration cache file.
| |
|
| |
| === KDETMP ===
| |
| Allows you to specify a path other than /tmp for KDE to store its temporary files.
| |
| | |
| === KDEVARTMP ===
| |
| Allows you to specify a path other than /var/tmp for KDE to store its variable files.
| |
| | |
| == Localization ==
| |
| | |
| === KDE_LANG ===
| |
| Allows you to override the KDE language configuration. For example, "KDE_LANG=fr kprogram &" starts a program in French if the necessary files are installed.
| |
| | |
| === KDE_UTF8_FILENAMES ===
| |
| If this environment variable is set, KDE assumes all filenames are in UTF-8 encoding, regardless of the current C locale.
| |
| | |
| == Networking ==
| |
| | |
| === KDE_NO_IPV6 ===
| |
| Set this variable to disable IPv6 support / IPv6 DNS lookups.
| |
| | |
| === KDE_USE_IDN ===
| |
| The content of this variable defines for which top level domains the usage of IDN is enabled. If not set, "at:ch:cn:de:dk:kr:jp:li:no:se:tw" will be used.
| |
| | |
| == Performance Related ==
| |
| | |
| === KDE_IS_PRELINKED ===
| |
| Set this variable to indicate that you have prelinked your KDE binaries and libraries.
| |
|
| |
| === KDE_MALLOC ===
| |
| If set to "1" the fast malloc routine provided in kdecore is used if KDE was compiled with --enable-fast-malloc, otherwise the libc's routine is used.
| |
| | |
| === KDE_NOUNLOAD ===
| |
| If this variable is set, then KLibLoader is told to never unload dynamically opened libraries.
| |
|
| |
| === KDE_DOUNLOAD ===
| |
| If this variable is set, then KLibLoader is told to always try to unload dynamically opened libraries. Warning, this will most probably lead to crashes!
| |
| | |
| == Troubleshooting and Debugging ==
| |
| | |
| === KDE_DEBUG ===
| |
| Set this variable to disable the KDE crash handler (same as --nocrashhandler command line option).
| |
| | |
| === KDE_COLOR_DEBUG ===
| |
| Starting with KDE 4, setting this variable will get you colorful debug output.
| |
| | |
| === KDE_FORK_SLAVES ===
| |
| Set this variable to spawn KIO-slaves directly from the application process itself. (By default, KIO-slaves are spawned using klauncher/kdeinit.) This option is useful if the KIO-slave should run in the same environment as the application; this can be the case with Clearcase.
| |
| | |
| == freedesktop.org Compliance ==
| |
| | |
| The following environment variables are defined in the [http://freedesktop.org/wiki/Standards/basedir-spec freedesktop.org base directory specification] and are supported by all XDG-compliant environments and applications, such as KDE.
| |
| | |
| === XDG_DATA_HOME ===
| |
| Defines the base directory relative to which user specific data files should be stored. If <tt>$XDG_DATA_HOME</tt> is either not set or empty, a default equal to {{path|$HOME/.local/share}} is used.
| |
|
| |
| === XDG_CONFIG_HOME ===
| |
| Defines the base directory relative to which user specific configuration files should be stored. If <tt>$XDG_CONFIG_HOME</tt> is either not set or empty, a default equal to {{path|$HOME/.config}} is used.
| |
|
| |
| === XDG_DATA_DIRS ===
| |
| Defines the preference-ordered set of base directories to search for data files in addition to the <tt>$XDG_DATA_HOME</tt> base directory. The directories in <tt>$XDG_DATA_DIRS</tt> should be separated with a colon ':'. If <tt>$XDG_DATA_DIRS</tt> is either not set or empty, a value equal to {{path|/usr/local/share/:/usr/share/}} is used.
| |
|
| |
| === XDG_CONFIG_DIRS ===
| |
| Defines the preference-ordered set of base directories to search for configuration files in addition to the <tt>$XDG_CONFIG_HOME</tt> base directory. The directories in <tt>$XDG_CONFIG_DIRS</tt> should be separated with a colon ':'. If <tt>$XDG_CONFIG_DIRS</tt> is either not set or empty, a value equal to {{path|/etc/xdg}} is used.
