These are the generic installation instructions for the K Desktop Environment. Please complement your reading with the READMEs and INSTALLs that come along with the package. Please read them carefully and try to help yourself out if anything goes wrong. If you need further assistance, consider joining the KDE mailing lists (see our web site instructions for joining the KDE mailing lists) or newsgroups.
4.1. | To the would-be converts |
So you have heard the rumors. Or you have seen the screenshots. And you are dying to get hold of KDE. But you know next to nothing about this whole “alternative OS” business. Don't worry! You only need to do some (well, maybe not some) reading, that's all! KDE does not run on Windows® 95/98/NT or OS/2 (yet). To run KDE, you need to have a UNIX® system. Please refer to Q: 2.2. for more details. Decide on a platform and set it up for your system. This FAQ can not help you with this, since KDE runs on many UNIX® platforms. Finally, you are ready to commence the KDE installation. Please start reading from the next section. To get KDE, please refer to Q: 3.1. . Last but not least, if you encounter any problems while installing KDE, please do not hesitate to make use of the KDE mailing lists and newsgroups. But do bear this in mind: no question is too silly to ask, but some are too silly to answer, especially when they are already answered in this FAQ. Good luck and have fun! | |
4.2. | Available package formats |
You can find several kinds of binary and source packages for different distributions and operating systems on the ftp://ftp.kde.org/pub/kde/. The binary packages are not made by the KDE Team, but by the distributors themselves, or some dedicated individuals. Please refer to KDE Package Policy Explained for information about the KDE Package Policy. The only “official” release is the source tar.bz2 packages. Please refer to the READMEs and INSTALLs in the several binaries directories. For a list of the available packages for a release, refer to the relevant info page. For the latest release this is the KDE 3.0 Info Page. | |
4.3. | Prerequisites |
For KDE 3.0, you need the Qt™ library version 3.0.2 or higher. Please make sure you download the correct Qt™. You will also need the header files, if you want to compile KDE yourself. They are all available, at no cost, from http://www.trolltech.com/download. In addition, there are optional libraries that might improve KDE if installed on your system. An example is OpenSSL which will enable Konqueror to browse web pages securely and is needed in a version >=0.9.6. These should be provided by your distributor; if not, ask for an update. | |
4.4. | Description of the base packages |
The base distribution currently consists of eleven packages. Some are required, while others are optional. Each package is available in each of the aforementioned package formats.
arts and then kdelibs should be installed before everything else, and kdeaddons last. The other packages can be installed in any arbitrary order. Most package management tools will let you put all these packages in one directory and install them all at once, figuring out the dependencies as they go. | |
4.5. | Installation instructions for the different package formats |
ImportantPlease do not forget to read the README and INSTALL files if they are available.
| |
4.6. | Post-installation procedures |
First of all, please make sure that you have added KDE's binary installation directory (e.g. /opt/kde/bin) to your PATH and KDE's library installation directory to your LD_LIBRARY_PATH (only necessary on systems that do not support rpath; on Linux® ELF, it should work without). This environment variable may be called differently on some systems, e.g. it is called SHLIB_PATH on IRIX®. Then set the environment variable KDEDIR to the base of your KDE tree, e.g. /opt/kde. CautionPlease bear in mind that it is unwise to set LD_LIBRARY_PATH blindly. In the vast majority of cases it is unnecessary and can do more harm than good. There is a web page written by Dave Barr explaining the evils of LD_LIBRARY_PATH and it can be found at http://www.cis.ohio-state.edu/~barr/ldpath.html. Even though you can use most of the KDE applications simply by calling them, you can only benefit fully from KDE's advanced features if you use the KDE window manager and its helper programs. In order to make it easy for you, we have provided a simple script called startkde which gets installed in $KDEDIR/bin and is therefore in your path. Edit the file .xinitrc in your home directory (make a backup copy first!), remove everything that looks like calling a window manager, and insert startkde instead. Restart the X Window System®. If you use kdm/xdm, you will have to edit the file .xsession instead of .xinitrc. And if there is no .xinitrc or .xsession in your home directory, simply create a new one with just one line containing startkde. NoteSome systems (notably Red Hat® Linux®) use .Xclients instead. This should present you with a new shining KDE desktop. You can now start to explore the wonderful world of KDE. In case you want to read some documentation first, there is a highly recommended Quick Start guide available. Furthermore, every application has an online help that is available via the help menu. | |
4.7. | Should I remove old version xyz before installing a new one? |
In principle, this is not necessary. RPM and Debian packages should take care of all dependencies. If you compile the source code yourself, you should take care not to compile different versions of the KDE packages. So if you install a new version, please first make and install kdesupport, then kdelibs, then kdebase. One thing you should avoid: installing two or more versions of KDE in parallel. This might happen if you specify a different target directory for one version than for the other. The result may be unpredictable. The same is true if you have different versions of Qt™ installed at the same time. This happens easily if you already have an old Qt™ version installed with a Linux® distribution. | |
4.8. | How do I start KDE? |
The most comfortable method to start KDE is to use the startkde script. Simply put the line startkde at the end of your .xsession file (or your .xinitrc or .Xclients file if you are not using kdm or xdm). Please also remove the lines that start your previous window manager. If there is no .xsession, .xinitrc, or .Xclients in your home directory, simply create a new one that contains just one line: startkde. | |
4.9. | Is it possible to install KDE in a user directory? |
Yes, you can install KDE in any directory you want. What you have to do depends on the kind of packages you want to install: Procedure 4.4. Source packages
Procedure 4.5. RPM packages
NoteAlthough KDE will run from a user directory, there are some problems with programs that require suid root, e.g. the programs in the kdeadmin package. But since they are not meant to be run by users in the first place, this is nothing to worry about. However, on systems using shadow passwords, the screensavers have to be suid root to enable password access for unlocking the screen, so this option will not work. | |
4.10. | startkde fails with can not connect to X server. What is wrong? |
You probably tried to start the X server with startkde. The X server is started with startx. startkde is the script that should be run from your .xinitrc, .xsession, or .Xclients to activate the window manager and the necessary server daemons for KDE. See also Q: 4.8. . | |
4.11. | KDE on AIX®? |
If you have trouble building KDE on AIX® check out Stefan Westerfeld's Running KDE on Aix page for lots of help on building KDE on this exceptional UNIX® variant. | |
4.12. | KDE on a laptop? |
If you can get the X Window System® to run, you should not have any problem getting KDE to run on it. In addition, you might find the following links helpful: | |
4.13. | I do not like the default KDE directory after installation. How do I move it without breaking anything? |
Assuming the default is /opt/kde and you want to move it to /usr/local/kde, here's what you have to do: Procedure 4.6.
This will put all your KDE files in /usr/local/kde but everything is still accessible from /opt/kde. | |
4.14. | What files can I delete from my KDE install directory? Can all the *.h, *.c and *.o files be safely removed? |
There should not be any need to keep the .c and .o files, but you might want to keep the .h files, as they are used by includes if you ever want to compile your own KDE programs. But if you wish to add patches to the source programs as they become available (rather than downloading everything again), then they should stay. | |
4.15. | Will I lose my current settings when I upgrade KDE? |
No. In most cases KDE will be able to transport your settings intact. You may need to reenter passwords in some applications (such as KMail or KNode) but most other settings will be safe. There were mixed reports of results between some previous versions of KDE. To be safe, you may like to back up your entire KDE configuration. Settings are kept in the .kde or .kde2 subdirectory in your home directory. Copy your old .kde/.kde2 directory to a backup location, install KDE 3.0, and then copy back any necessary mail and news settings. That said, most people can make a direct upgrade, without removing the old .kde directory, without a hitch. | |
4.16. | I upgraded KDE and it seemed to go fine, but when I start it, I get a blank grey screen, and nothing happens. There are errors in the console about DCOPserver. What's going on? |
KDE uses several temporary files during it's operation. These are usually to be found in the following locations:
If the symlinks get broken, usually because a cron or shutdown script is emptying out the /tmp directory, then strange things will happen. These files, and the symlinks, will all be created automatically at the start of KDE so you can safely remove them while KDE is not running. Normally (i.e. when not upgrading between KDE versions) it's quite safe to leave these files intact, and you may shave a few seconds off your KDE startup time by doing so. | |
4.17. | Compiling kdebase gives me a bin/sh: msgfmt: command not found error! |
You need the GNU msgfmt which is part of the GNU i18n package gettext. You should be able to download it from any decent GNU mirrors. | |
4.18. | How do I uninstall KDE applications compiled from scratch? |
You can uninstall your programs by typing make uninstall in the directory where you did make install. If you have already nuked away that directory, then there is only one way, and it is not good: go to $KDEDIR/bin and start deleting files one by one. | |
4.19. | What is up with GIF support? |
This has something to do with Unisys' LZW patent. GIF support is turned off from Qt™ 1.44 onwards by default. When you want to use GIFs and have the relevant license, recompile Qt™ with GIF support. ./configure -gif. | |
4.20. | How do I install KDE themes? |
There is a Theme Manager in KDE 2.2.1, so please refer to the Control Center Help for further reference, or look at kde.themes.org for KDE2 themes. |
