<para>To the would-be converts</para>
</question>
<answer>

<para>So you have heard the rumors. Or you have seen the screenshots.
And you are dying to get hold of &tde;. But you know next to nothing
about this whole <quote>alternative operating system</quote> business. Don't worry!
You only need to do some (well, maybe not some) reading, that's
all!</para>

<para>&tde; does not run on any version of &Microsoft; &Windows; or OS/2 (yet). To run
&tde;, you need to have a &UNIX; system. Please refer to <xref
linkend="platform"/> for more details.</para>

<para>Decide on a platform and set it up for your system. This
<acronym>FAQ</acronym> can not help you with this, since &tde;<ulink
url="http://www.kde.org"> runs on many &UNIX;</ulink> platforms. </para>

<!-- Taken out because we can not help with all platforms and KDEisnotLINUX -->

<para>Finally, you are ready to commence the &tde; installation.
Please start reading from the next section. To get &tde;, please
refer to <xref linkend="where-to-get-tde"/>. Last but not least, if
you encounter any problems while installing &tde;, please do not
hesitate to make use of the &tde; <link
linkend="mailing-lists">mailing lists</link> and <link
linkend="newsgroups">newsgroups</link>. But do bear this in mind: no
question is too silly to ask, but some are too silly to answer,

<question>
<para>What kind of hardware do I need to run &tde; ?</para>
</question>
<answer>
<para>To run &tde; it is recommended that you have at least a pentium II processor, 64MB of memory and 500MB of free disk space for a basic installation. While &tde; may run on slower configurations than this, performance can be severely impaired. Generally, if your computer runs an &X-Server; already with other desktop environments or window managers it's probably fast enough to run &tde;.</para>

<para>Available package formats</para>
</question>
<answer>


<para>You can find several kinds of binary and source packages for
different distributions and operating systems on the &kde-ftp;. The
binary packages are not made by the &tde; Team, but by the
distributors themselves, or some dedicated individuals. Please refer to
<ulink url="http://dot.kde.org/986933826/">&tde; Package Policy
Explained</ulink> for information about the &tde; Package Policy. The
only <quote>official</quote> release is the source tar.bz2
packages. Please refer to the <filename>README</filename>s and
<filename>INSTALL</filename>s in the several binaries folders. For
a list of the available packages for a release, refer to the relevant

<!-- rewrite to make it more general, pointing to the according webpages? -->

<para>For &tde; 3.4.1, you need the &Qt; library version 3.3 or greater.
Please make sure you download the correct &Qt;. You will
also need the header files, if you want to compile &tde;
yourself. They are all available, at no cost, from <ulink
url="http://www.trolltech.com/products/download">http://www.trolltech.com/download</ulink>.
In addition, there are optional libraries that might improve &tde; 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

<question>
<para>Post-installation procedures</para>
</question>
<answer>
<para>First of all, please make sure that you have added &tde;'s binary
installation folder (&eg; <filename
class="directory">/usr/local/kde/bin</filename>) to your <envar>PATH</envar>
and &tde;'s
library installation folder to your <envar>LD_LIBRARY_PATH</envar> (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, &eg; it is called
<envar>SHLIB_PATH</envar> on &IRIX;. Then set the environment variable
<envar>TDEDIR</envar> to the base of your &tde; tree, &eg; <filename
class="directory">/usr/local/kde</filename>.
<caution>
<para>Please bear in mind that it is unwise to set
<envar>LD_LIBRARY_PATH</envar> blindly. In the vast majority of cases it is
unnecessary and can do more harm than good. There is a web page
written by <ulink url="mailto:barr@cis.ohio-state.edu">Dave
Barr</ulink> explaining the evils of <envar>LD_LIBRARY_PATH</envar> and it can be
found at <ulink
url="http://www.cis.ohio-state.edu/~barr/ldpath.html">http://www.cis.ohio-state.edu/~barr/ldpath.html</ulink>.</para>
</caution>
</para>
<para>Even though you can use most of the &tde; applications simply by
calling them, you can only benefit fully from &tde;'s advanced
features if you use the &tde; window manager and its helper
programs.</para>
<para>In order to make it easy for you, we have provided a simple
script called <filename>starttde</filename> which gets installed in <filename
class="directory">$<envar>TDEDIR</envar>/bin</filename> and is therefore in your
path.</para>
<para>Edit the file <filename>.xinitrc</filename> in your home folder (make a backup
copy first!), remove everything that looks like calling a window
manager, and insert <command>starttde</command> instead. Restart the &X-Server;. If you use
&tdm;/<application>xdm</application>, you will have to edit the file <filename>.xsession</filename> instead of
<filename>.xinitrc</filename>. And if there is no <filename>.xinitrc</filename> or <filename>.xsession</filename> in your home
folder, simply create a new one with just one line containing
<command>starttde</command>.
<note>
<para>Some systems (notably &RedHat; &Linux;) use <filename>.Xclients</filename>
instead.</para>
</note></para>
<para>This should present you with a new shining &tde; desktop. You
can now start to explore the wonderful world of &tde;. In case you
want to read some documentation first, there is a highly recommended

file if you are not using &tdm; or <application>xdm</application>). Please
also remove the lines that start your previous window manager. If there is no

root privileges, which are needed to access the shadow passwords.

<question>
<para>I upgraded &tde; and it seemed to go fine, but when I start it,
I get a blank gray screen, and nothing happens. There are errors in

</question>

<answer>
<para>
&tde; uses several temporary files during its operation.
These are usually to be found in the following locations:</para>
<itemizedlist>
<listitem><para><filename>~/.DCOPserver-*</filename> (there are usually two of these; one is a symlink to the other)</para></listitem>
<listitem><para><filename>~/.kde/socket-<replaceable>hostname</replaceable></filename></para></listitem>
<listitem><para><filename>~/.kde/tmp-<replaceable>hostname</replaceable></filename> which is normally a symlink to the next file:</para></listitem>
<listitem><para><filename>/tmp/tmp-kde-<replaceable>USER</replaceable></filename></para></listitem>
<listitem><para><filename>~/.kde/socket-<replaceable>hostname</replaceable></filename> which is also normally a symlink to:</para></listitem>
<listitem><para><filename>/tmp/tdesocket-<replaceable>USER</replaceable></filename></para></listitem>
</itemizedlist>

<para>If the symlinks get broken, usually because a
<command>cron</command> or shutdown script is emptying out the
<filename class="directory">/tmp</filename> folder, then strange
things will happen. These files, and the symlinks, will all be
created automatically at the start of &tde; so you can safely remove
them <emphasis>while &tde; is not running</emphasis>.</para>

<para>If you are only getting a gray screen when you start &tde;, or if you get an error message telling you to <errorname>Check your installation</errorname>, then shut down X and delete all the files listed above, then try to restart X.</para>

<para>Normally (&ie; when not upgrading between &tde; versions) it's
quite safe to leave these files intact, and you may shave a few
seconds off your &tde; startup time by doing so.</para>

<question>
<para>Is TDE backwards or binary compatible with KDE 3?</para>
</question>
<answer>
<para>While many programs designed on KDE 3 will compile on Trinity, binary
compatibility with KDE 3 is not a goal of the TDE project.</para>

<question>
<para>Is TDE backwards or binary compatible with previous releases of TDE?</para>
</question>
<answer>
<para>Possibly, but binary compatibility is not a project goal with major point
releases. A package that built on a previous version of TDE but no longer builds
on the current release should be brought to the attention of the developers.</para>

<question>
<para>Is my KDE3 profile directory compatible with Trinity?</para>
</question>
<answer>
<para>Not quite but don't worry. Some "scrubbing" cleanup is required to migrate
a KDE3 profile. For new users or those with little customization we recommend
creating a fresh profile. For those long-time users who cringe at the thought
of recreating their desktop, we provide a migratekde3 shell script. That script
copies a $HOME/.kde3 profile directory to $HOME/.trinity and performs the required
"scrubbing" cleanup. Although the script has been tested we provide the tool "as is"
with no warranties or guarantees. (The script works really well, actually. :-))</para>

<question>
<para>How do I uninstall &tde; applications compiled from
source?</para>
</question>
<answer>
<para>You can uninstall your programs by typing <command>make
uninstall</command> in the folder where you did <command>make
install</command>. If you have already deleted that folder,
then there is only one way, and it is not good: go to <filename
class="directory">$<envar>TDEDIR</envar>/bin</filename> and start deleting files
one by one.</para>
<para>If you expect to find yourself in this situation, you might want to
consider a program such as &GNU; <application>stow</application>, found at
<ulink url="http://www.gnu.org/software/stow/stow.html">http://www.gnu.org/software/stow/stow.html</ulink>.</para>

<question id="gif">
<para>What is up with &GIF; support?</para>
</question>
<answer>
<para>This has to do with issues with Unisys' &LZW; patent. &GIF;
support is turned off from &Qt; 1.44 onwards by default. When you want to use
&GIF;s and have the relevant license, recompile &Qt; with &GIF; support.
<command>./configure <option>-gif</option></command>.</para>
