<listitem><para>Can you dialup to your <acronym>ISP</acronym> without using &kppp;? If you cannot, then perhaps &kppp; is not the culprit after all.</para></listitem>
<listitem><para>Have you gone through the &kppp; documentation at least three times and followed its instructions and trouble-shooting suggestions?</para></listitem>
<para>The &kppp; documentation can be accessed through the <application>&kde; Help Centre</application>. Last, but not least, the &kppp; homepage is at <ulink url="http://ktown.kde.org/~kppp/">http://ktown.kde.org/~kppp/</ulink>.</para>
<para>Now, if you still encounter problems, here's what might help you solve them:</para>
<varlistentry><term>How do I change the &MTU; setting in &kppp;?</term>
<listitem><para>Open up the &kppp; dialogue box and select <guibutton>Setup</guibutton>. Choose an existing account and click <guibutton>Edit</guibutton>, or <guibutton>New</guibutton> to create a new dialup account. Select the <guilabel>Dial</guilabel> tab and click <guibutton>Arguments</guibutton>. Type what you want to change in the Argument textbox (⪚ <userinput>mtu 296</userinput>) and click <guibutton>Add</guibutton>. When you are satisfied, click <guibutton>Close</guibutton>.</para>
<para>To check whether the options <quote>took</quote>, do one of the following:</para>
<para>In a terminal window, run <userinput><command>/sbin/ifconfig</command> ppp0</userinput> and look at the reported &MTU; in the output. It should match your request.</para>
<listitem><para>Add <option>debug</option> and <option>kdebug</option> (each on a separate line) to your <filename>/etc/ppp/options</filename> file and restart your &PPP; session. You will find debugging messages in <filename>/var/log/messages</filename>, including &MRU; and &MTU; settings.</para></listitem>
<para>If you want, the &MRU; and &MTU; settings can be added to the <filename>options</filename> file, one complete setting per line, no quotes or dashes.</para></listitem>
<listitem><para>The default &MTU; value is 1500, which maybe too large for a dialup connection. Try changing it to a smaller value like <userinput>296</userinput> or <userinput>576</userinput>.</para></listitem>
<listitem><para>Check in your <filename class="directory">$<envar>HOME</envar>/.trinity/share/config</filename> for the <filename>kppprc</filename>. Ensure the correct modem speed is actually defined there.</para></listitem>
<term>How do I perform a simple <quote>copy</quote> from &konsole; to anything else?</term>
<listitem><para>When I do a <command>ls</command>, first I select with the mouse the desired text, press <keycombo action="simul">&Ctrl;<keycap>C</keycap></keycombo>, then I make the target application active, point the mouse to the relevant part and press <keycombo action="simul">&Ctrl;<keycap>V</keycap></keycombo>. Alternatively, highlight the text by dragging with the &LMB; down and paste by clicking with the &MMB; (or both buttons if you are using a 2 button mouse with 3 button emulation). </para></listitem>
<para><application>FontConfig</application> must find the three fonts installed in: <filename class="directory">$<envar>TDEDIR</envar>/share/fonts</filename>. If the &kde; install does not install these fonts in a directory that already exists (⪚ <filename class="directory">/usr/share/fonts</filename>) then you must add this directory to the configuration file <filename class="directory">/etc/fonts/local.conf</filename>. This should be the first line after <quote><fontconfig></quote>. For example: <programlisting>
</programlisting> After adding the directory, run (as root): <userinput><command>fc-cache</command> -v</userinput> and check that it found the directory.</para>
