<title>The Graphical Installer</title>
<para>
The graphical version of the installer is only available for a limited
number of architectures, including &arch-title;. The functionality of
the graphical installer is essentially the same as that of the regular
installer as it basically uses the same programs, but with a different
frontend.
</para><para>
Although the functionality is identical, the graphical installer still has
a few significant advantages. The main advantage is that it supports more
languages, namely those that use a character set that cannot be displayed
with the regular <quote>newt</quote> frontend. It also has a few usability
advantages such as the option to use a mouse, and in some cases several
questions can be displayed on a single screen.
</para><para arch="any-x86">
The graphical installer is available with all CD images and with the
hd-media installation method. To boot the graphical installer simply select
the relevant option from the boot menu. Expert and rescue mode for the
graphical installer can be selected from the <quote>Advanced options</quote>
menu. The previously used boot methods <userinput>installgui</userinput>,
<userinput>expertgui</userinput> and <userinput>rescuegui</userinput> can
still be used from the boot prompt which is shown after selecting the
<quote>Help</quote> option in the boot menu.
</para><para arch="any-x86">
There is also a graphical installer image that can be netbooted. And there
is a special <quote>mini</quote> ISO image<footnote id="gtk-miniiso">
<para>
The mini ISO image can be downloaded from a &debian; mirror as described
in <xref linkend="downloading-files"/>.
Look for <filename>netboot/gtk/mini.iso</filename>.
</para>
</footnote>, which is mainly useful for testing.
</para><para arch="powerpc">
For &arch-title;, currently only an experimental <quote>mini</quote> ISO
image is available<footnote id="gtk-miniiso">
<para>
The mini ISO image can be downloaded from a &debian; mirror as described
in <xref linkend="downloading-files"/>.
Look for <filename>netboot/gtk/mini.iso</filename>.
</para>
</footnote>. It should work on almost all PowerPC systems that have
an ATI graphical card, but is unlikely to work on other systems.
</para><para>
Just as with the regular installer it is possible to add boot parameters
when starting the graphical installer.
</para>
<note><para>
The graphical installer requires significantly more memory to run than
the regular installer: &minimum-memory-gtk;. If insufficient memory is
available, it will automatically fall back to the regular
<quote>newt</quote> frontend.
</para><para>
If the amount of memory in your system is below &minimum-memory;,
the graphical installer may fail to boot at all while booting the
regular installer would still work. Using the regular installer is
recommended for systems with little available memory.
</para></note>
<sect2 id="gtk-using">
<title>Using the graphical installer</title>
<para>
As already mentioned, the graphical installer basically works the same as
the regular installer and thus the rest of this manual can be used to guide
you through the installation process.
</para><para>
If you prefer using the keyboard over the mouse, there are two things you
need to know. To expand a collapsed list (used for example for the selection
of countries within continents), you can use the <keycap>+</keycap> and
<keycap>-</keycap> keys. For questions where more than one item can be
selected (e.g. task selection), you first need to tab to the
&BTN-CONT; button after making your selections; hitting
enter will toggle a selection, not activate &BTN-CONT;.
</para><para>
If a dialog offers additional help information, a <guibutton>Help</guibutton>
button will be displayed. The help information can be accessed either by
activating the button or by pressing the <keycap>F1</keycap> key.
</para><para>
To switch to another console, you will also need to use the
<keycap>Ctrl</keycap> key, just as with the X Window System. For example,
to switch to VT2 (the first debug shell) you would use: <keycombo>
<keycap>Ctrl</keycap> <keycap>Left Alt</keycap> <keycap>F2</keycap>
</keycombo>. The graphical installer itself runs on VT5, so you can use
<keycombo> <keycap>Left Alt</keycap> <keycap>F5</keycap> </keycombo>
to switch back.
